setLimit
public void setLimit(int limit)
Sets the maximum number of geometries to read.- Parameters:
limit
- the maximum number of geometries to read
-
setOffset
public void setOffset(int offset)
Sets the number of geometries to skip before storing.- Parameters:
offset
- the number of geometries to skip
-
read
public java.util.List read() throws java.io.IOException, ParseException
Reads a sequence of geometries. If an offset is specified, geometries read up to the offset count are skipped. If a limit is specified, no more than limit geometries are read.- Returns:
- the list of geometries read
- Throws:
java.io.IOException
- if an I/O exception was encounteredParseException
- if an error occurred reading a geometry
