Method Detail

getGeometryAttributes

public Map<String,Object> getGeometryAttributes()

Returns a read-only view to all currently defined geometry attributes. You can copy all currently defined geometry attributes to another geometry using target.setGeometryAttributes(source.getGeometryAttributes()) These attributes are copied then, not shared. Thus modifying either source or target afterwards will not affect the other.

setGeometryAttributes(DataListSet)

getGeometryAttributes

public Object getGeometryAttributes(String name)

setGeometryAttributes

public void setGeometryAttributes(Map<String,Object> attrSet)

setGeometryAttributes

public void setGeometryAttributes(String attr,
                                  Object value)

addGeometryListener

public void addGeometryListener(GeometryListener listener)

removeGeometryListener

public void removeGeometryListener(GeometryListener listener)

getGeometryAttributeCathegories

public Set<String> getGeometryAttributeCathegories()

getNumEntries

public int getNumEntries(String attributeCategory)

The number of entries defines the length of all data lists associated with the target geometry attributes.

Parameters:

attributeCategory - key for target data list set

setNumEntries

public void setNumEntries(String attributeCategory,
                          int numEntries)

Sets the number of entries, implies removal of all previously defined such geometries attributes

Parameters:

attributeCategory - key for target data list set

numEntries - the number of vertices to set >=0

getAttributes

public DataListSet getAttributes(String attributeCategory)

Returns a read-only view to all currently defined target geometry attributes.

Parameters:

attributeCategory - key for target data list set
