Member Function Documentation

◆ isValid() [1/2]

bool QgsVertexId::isValid ( ) const
inline

Returns true if the vertex id is valid.

Definition at line 45 of file qgsvertexid.h.

◆ isValid() [2/2]

bool QgsVertexId::isValid ( const QgsAbstractGeometry geom) const

Returns true if this vertex ID is valid for the specified geom.

Definition at line 19 of file qgsvertexid.cpp.

◆ operator!=()

bool QgsVertexId::operator!= ( QgsVertexId  other) const
inline

Definition at line 51 of file qgsvertexid.h.

◆ operator==()

bool QgsVertexId::operator== ( QgsVertexId  other) const
inline

Definition at line 47 of file qgsvertexid.h.

◆ partEqual()

bool QgsVertexId::partEqual ( QgsVertexId  o) const
inline

Returns true if this vertex ID belongs to the same part as another vertex ID.

Definition at line 59 of file qgsvertexid.h.

◆ ringEqual()

bool QgsVertexId::ringEqual ( QgsVertexId  o) const
inline

Returns true if this vertex ID belongs to the same ring as another vertex ID (i.e.

the part and ring number are equal).

Definition at line 68 of file qgsvertexid.h.

◆ vertexEqual()

bool QgsVertexId::vertexEqual ( QgsVertexId  o) const
inline

Returns true if this vertex ID corresponds to the same vertex as another vertex ID (i.e.

the part, ring number and vertex number are equal).
