overridevirtual |
Applies a hierarchical visitor to this geometry.
v | A hierarchical visitor. |
true | The execution was aborted by the visitor. |
false | The execution completed. |
Implements gis::Linearring.

Reimplemented from gis::Geographic_linestring.
|
inlineoverridevirtual |
Returns the last point of the linestring.
Reimplemented from gis::Geographic_linestring.
|
inlineoverridevirtualnoexcept |
Removes all points from the linestring.
Reimplemented from gis::Geographic_linestring.
|
inlineoverridevirtual |
This implementation of clone() uses a broader return type than other implementations.
This is due to the restraint in some compilers, such as cl.exe, that overriding functions with ambiguous bases must have covariant return types.
Reimplemented from gis::Geographic_linestring.
|
inlineoverridevirtual |
Gets the coordinate system.
Reimplemented from gis::Geographic_linestring.
|
inlineoverridevirtual |
Checks if the linestring is empty.
Here, the definition of empty is that the linestring does not contain any points. An invalid linestring with only one coordinate is not empty.
true | The linestring is empty. |
false | The linestring is not empty. |
Reimplemented from gis::Geographic_linestring.
|
inlineoverridevirtual |
Reimplemented from gis::Geographic_linestring.
|
inlineoverridevirtual |
Returns the first point of the linestring.
Reimplemented from gis::Geographic_linestring.
|
inlineoverridevirtual |
Check if this is an empty geometry.
The definition of empty geometries is the one in SFA-CA (OGC 06-103r4, Sect. 6.1.2.2), i.e., an empty point set.
true | The geometry represents the empty point set. |
false | The geometry represent a non-empty point set. |
