Returns an iterator to iterate through the entities of this layer

Returns:

an iterator to iterate the layer

getFieldName

public String getFieldName(int i)

Description copied from interface: es.unex.sextante.dataObjects.IVectorLayer

Returns the name of a given field in the attributes table

Parameters:

i - the zero-based field index

Returns:

the name of the selected attribute field

getFieldType

Return a class representing the data type of a given field

Parameters:

i - the zero-based field index

Returns:

the data type of the selected attribute field

getFieldCount

public int getFieldCount()

Returns:

the number of attributes associates to each geometry

getShapesCount

public int getShapesCount()

Description copied from interface: es.unex.sextante.dataObjects.IVectorLayer

Returns the number of features in this layer

Specified by:

getShapesCount in interface es.unex.sextante.dataObjects.IVectorLayer

postProcess

public void postProcess()

Description copied from interface: es.unex.sextante.dataObjects.IDataObject

This method post-processes the object after it has been created. If, for instance, data are kept in memory before they are dumped to file, this method should write that file.

getFilename
