Member Function Documentation

isValid() [1/2]

bool QgsVertexId::isValid ( ) const

inline

Returns true if the vertex id is valid.

Definition at line 46 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 52 of file qgsvertexid.h.

operator==()

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

inline

Definition at line 48 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 60 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 69 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).
