pygplates.GpmlPropertyDelegate

class pygplates.GpmlPropertyDelegate

Bases: pygplates.PropertyValue

A property value that represents a reference, or delegation, to a property in another feature.

New in version 21.

__init__(feature_id, property_name, property_type)

Create a reference, or delegation, to a property in another feature.

Parameters:

• feature_id (FeatureId) – the referenced feature
• property_name (PropertyName) – the name of the referenced property
• property_type (a class object of a property type (derived from PropertyValue) except Enumeration and time-dependent wrappers GpmlConstantValue, GpmlIrregularSampling and GpmlPiecewiseAggregation.) – the type of the referenced property

property_delegate = pygplates.GpmlPropertyDelegate(
    referenced_feature.get_feature_id(),
    pygplates.PropertyName.gpml_center_line_of,
    pygplates.GmlLineString)

Methods

__init__(feature_id, property_name, …)	Create a reference, or delegation, to a property in another feature.
accept_visitor(visitor)	Accept a property value visitor so that it can visit this property value.
clone()	Create a duplicate of this property value (derived) instance, including a recursive copy of any nested property values that this instance might contain.
get_feature_id()	Returns the feature ID of the feature containing the delegated property.
get_geometry()	Extracts the geometry if this property value contains a geometry.
get_property_name()	Returns the property name of the delegated property.
get_property_type()	Returns the property type of the delegated property.
get_value([time=0])	Extracts the value, of this possibly time-dependent property value, at the reconstruction time.

get_feature_id()

Returns the feature ID of the feature containing the delegated property.

Return type:FeatureId

get_property_name()

Returns the property name of the delegated property.

Return type:PropertyName

get_property_type()

Returns the property type of the delegated property.

For example, it might return pygplates.GmlLineString which is a class object (not an instance).

Return type:a class object of the property type (derived from PropertyValue)
