pygplates.GpmlTopologicalPolygon

class pygplates.GpmlTopologicalPolygon

Bases: PropertyValue

A topological polygon geometry that is resolved from topological sections.

A GpmlTopologicalPolygon can also be pickled.

Added in version 0.21.

Changed in version 0.42: Added pickle support.

__init__(exterior_sections)

Create a topological polygon made from topological sections.

Parameters:: exterior_sections (Any sequence such as a list or a tuple) – A sequence of GpmlTopologicalSection elements

topological_polygon = pygplates.GpmlTopologicalPolygon(topological_sections)

Methods

`__init__`(exterior_sections)	Create a topological polygon made from topological sections.
`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_boundary_sections`()	Returns the `boundary sections` in a sequence that behaves as a python `list`.
`get_exterior_sections`()	Same as `get_boundary_sections()`.
`get_geometry`()	Extracts the `geometry` if this property value contains a geometry.
`get_value`([time=0])	Extracts the value, of this possibly time-dependent property value, at the reconstruction time.

get_boundary_sections()

Returns the boundary sections in a sequence that behaves as a python list.

Return type:: GpmlTopologicalSectionList

Modifying the returned sequence will modify the internal state of the GpmlTopologicalPolygon instance:

boundary_sections = topological_polygon.get_boundary_sections()

# Append a section
boundary_sections.append(pygplates.GpmlTopologicalLineSection(...))

Added in version 0.24.

get_exterior_sections(): Same as get_boundary_sections().
