WKTFileReader
Creates a new WKTFileReader given the File to read from and a WKTReader to use to parse the geometries.- Parameters:
file
- the File to read fromwktReader
- the geometry reader to use
-

Method Details

setLimit
public void setLimit(int limit) Sets the maximum number of geometries to read.- Parameters:
limit
- the maximum number of geometries to read
-
setStrictParsing
public void setStrictParsing(boolean isStrict) Allows ignoring WKT parse errors after at least one geometry has been read, to return a partial result.- Parameters:
isStrict
- whether to ignore parse errors
-
setOffset
public void setOffset(int offset) Sets the number of geometries to skip before storing.- Parameters:
offset
- the number of geometries to skip
-
read
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:
IOException
- if an I/O exception was encounteredParseException
- if an error occurred reading a geometry
