Geometric Functions

Function	Description	Parameter(s)
angle	Returns the angle between line segments. If the line segments intersect, the acute angle between the lines is returned. If the lines join at end points, the smaller of the two angles is returned. If there is an error, a negative value is returned. The result will be an angle in the range [0,pi], or [0,180] if the third parameter is 'true'.	A two point line segment. A two point line segment. (optional) A boolean flag set to true for degrees. Default is false, for radians.
area	Returns the area of a geometry in dataset units. If the geometry is a point or a line the result will be 0. If the geometry is a solid, the surface area will be returned. If the geometry is a complex geometry, the result will be the sum of the areas of each simple area in the complex geometry. Note: Any heighted 2D geometries will be projected down to 2 dimensions.	The input geometry.
boundary	Returns the boundary of a geometry For a simple or complex point, the boundary is a clear geometry. For a simple or complex line, the boundary is a complex point specifying the line end-points. A closed line has no end-points and returns a clear geometry. For a simple or complex area, the boundary is a simple or complex line containing all the rings in the area geometry. For a complex, the boundary will also be a complex; containing the same parts as those defined for points, lines and areas above.	The geometry for which the boundary is required.
buffer	Returns a geometry formed by taking a buffer zone around the input geometry at a fixed distance.	The geometry to buffer. The distance from the input geometry that the buffer zone will extend to. If this is negative then any 2D or 2.5D areas in the input geometry are buffered inwards; The sign of this parameter is ignored for 3D geometries. If this is smaller than geometric tolerance a copy of the input geometry is returned Note: The returned geometry is not guaranteed to be an area. (optional) The length of the line segments to build up the buffer zone. Specify this to control how many vertices are added to the rounded corners of the buffer. Use the default or a small value to generate more vertices for more accurate buffers. Use a large value for fewer vertices and faster processing. For example when buffering a point, use buffer_distance/4 to create a circle with 26 vertices. (optional) The square end proportion to determine how far from the end of the line to create the square end. A negative value produces rounded corners and a positive value produces a buffer with square end. This is not supported for 2.5D geometries. (optional) The mitre truncation proportion. A negative value produces rounded corners. A zero value produces a true bevel which would cut off the corner with a straight line. A value greater than zero would extend the bevel away from the geometry by a proportion of the buffer distance. A very large value would remove the bevel to create true mitres which might extend a long way if the angle is very sharp. This is not supported for 2.5D geometries.
change_dimension	Allows geometry to be changed from one dimensionality to another. Takes any geometry as input, and changes it to the dimensionality specified (one of 2, 2.5 or 3). The value of Z coordinates in the resulting geometry can be set using an optional argument. This can either be a real, which will be used to set vertices to a constant height, or a secondary geometry defining a plane, which will be used to align the new geometry. When changing to 2D, or from 3D to 3D, this argument is ignored. If this argument is not supplied, the following cases exist: When changing from 2D to heighted 2D, the Z coordinates will be set to NULL. When changing from 2D to 3D, an error will occur. When changing from heighted 2D to heighted 2D, existing values will be used. When changing from heighted 2D to 3D, the existing values will be used, but an error will occur if any null values exist. When changing from 3D to heighted 2D, the resulting geometry will be an approximation of the underside of the original geometry. Measures can be added to the geometry if required - these will be set to NULL unless specified using an optional argument. Trying to add measures when changing to heighted 2D will result in an error. If the input geometry already has measures: Setting add measures to false will remove them. Setting add measures to true but not providing the optional value will copy them to the new geometry. Setting add measures to true and providing a value will overwrite them.	The input geometry. The coordinate dimension to change to (2, 2.5, or 3). (Optional) A boolean flag specifying whether a measure should be added. Defaults to false.

The input geometry.

For lines, the output is a vertical surface with the specified height following the path of the line. For areas, the output is a solid of the specified height with a footprint of the input geometry. For complex geometries, the result will be a complex geometry containing extruded versions of all its components. For solids, an error will occur. Additionally: A negative height value will result in the geometry being extruded downwards instead of upwards. For 2D geometries, the Z coordinates of the input geometry will be set to 0. For heighted 2D geometries, the initial Z coordinates will be retained; however, any NULL heights will result in an error.

The default format allows just the date with no time to be specified. For example 2017-03-17 14:25:03 GMT or 2017-03-17. The time specified in milliseconds is from January 1, 1970, 00:00:00 GMT. Note: For more information about the format rules, refer to the Oracle documentation.	The date/time formatted (String), or time in milliseconds (Long). (optional) Format of the date/time string. If not specified the default format is used.

Topology Functions

Function	Description	Parameter(s)
is_structured	Tests if an object is topologically structured. Returns true if the object is structured and false otherwise.	The object to be tested

Function

Description

Parameter(s)

is_structured

Tests if an object is topologically structured.

Returns true if the object is structured and false otherwise.

The object to be tested

Validation Functions

Function	Description	Parameter(s)
rule_hotspot_attributes	Only relevant when used in an Action within an ActionMap. Returns the list of the names of the attributes that caused the non-conformance. For geometry checks this is the name of the geometry and for attribute checks it is the names of the attribute(s) that were implicated.
rule_hotspot_geometry	Only relevant when used in an Action within an ActionMap. Returns the hotspots from the rule that triggers this action. Hotspots are the locations of non-conformances, inferred from the rule. e.g. If a rule checks that geometries should not intersect, then a non-conformance hotspot geometry will be the geometry of the intersection. Not all rules will be able to infer a hotspot geometry so there is an optional parameter to provide the geometry to report when there is no hotspot, typically set to the original object's geometry.	(optional) A default value if no hotspots are found. The default value must be geometric.

Function

Description

Parameter(s)

rule_hotspot_attributes

Only relevant when used in an Action within an ActionMap.

Returns the list of the names of the attributes that caused the non-conformance.

For geometry checks this is the name of the geometry and for attribute checks it is the names of the attribute(s) that were implicated.

rule_hotspot_geometry

Only relevant when used in an Action within an ActionMap.

Returns the hotspots from the rule that triggers this action. Hotspots are the locations of non-conformances, inferred from the rule. e.g. If a rule checks that geometries should not intersect, then a non-conformance hotspot geometry will be the geometry of the intersection.

Not all rules will be able to infer a hotspot geometry so there is an optional parameter to provide the geometry to report when there is no hotspot, typically set to the original object's geometry.

(optional) A default value if no hotspots are found. The default value must be geometric.

Classes and Attributes Functions

Function	Description	Parameter(s)
class_get_attributes	Return a collection of strings containing the attributes on a class. This function returns the attributes from the class based on the Data Store input mapping target names.	The object from which to build the collection. Alternatively, this can be the name of the class that would be the source of the attributes.
class_get_attribute_type	Return the type of an attribute given an object or a class name and the attribute name. This function should be used in conjunction with functions: `class_get_attributes` `class_is_attribute_null`	The object or class containing the attribute The attribute name
class_get_attribute_value	Return the value of an attribute of an object	The object containing the attribute The name of the attribute to get the value of.
class_has_attribute	Checks if the specified class contains the specified user attribute. A third parameter containing the data store name can be provided to pinpoint the class. The data store name provided must be the full path of the data store without the type prefix, for example "Parent Folder/Data Store 1". Returns true if the specified class contains the specified attribute, otherwise returns false.	The class name. The attribute to search. (optional) The name of the data store that contains the class. (optional) Error if class not found. Defaults to false which means that if the specified class is not found then the built-in returns false. If set to true then it throws an exception when the specified class is not found and so alerts the user that the class name input is wrong.
class_is_attribute_null	Return TRUE if an attribute is NULL, otherwise return FALSE. This function should be used in conjunction with functions: `class_get_attributes` `class_get_attribute_type`	The object containing the attribute to test The name of the attribute to test
get_session_class_names	Returns the names of all classes in the session. An optional parameter can be provided to specify the data store that contains the classes to retrieve.	(optional). The data store that will be the source of the class names. The data store name provided must be the full path of the data store without the type prefix, for example "Parent Folder/Data Store 1".
session_has_class	Checks whether or not the class has been opened in an Open Data task in the session. A second parameter containing the data store name can be provided to pinpoint the class. The data store name provided must be the full path of the data store without the type prefix, for example "Parent Folder/Data Store 1". Returns true if the specified class is in the session, otherwise returns false.	Name of the class to look for (optional) Name of the data store that should contain the class.
