Here is the call graph for this function:

OccurrencesPtr TapirOccurrences::getAbsences ( const char * groupId )

inlinevirtual

Return the absences (abundance == 0) from a specific group.

Parameters

groupId Identifier for a group of occurrences (usually a species name).

Returns: Pointer to occurrences of the specified group. If the group was not found or not specified, an empty OccurrencesPtr is returned.

Reimplemented from OccurrencesReader.

Definition at line 106 of file TapirOccurrences.hh.

OccurrencesPtr TapirOccurrences::getPresences ( const char * groupId )

virtual

Return the presences (abundance > 0) from a specific group.

Parameters

groupId Identifier for a group of occurrences (usually a species name).

Returns: Pointer to occurrences of the specified group. If the group was not found or not specified, an empty OccurrencesPtr is returned.

Reimplemented from OccurrencesReader.
