AbstractWktDecoder

java.lang.Object
- org.geolatte.geom.codec.AbstractWktDecoder<T>

Type Parameters:

T - the type of the decoded WKT.

Direct Known Subclasses:

CrsWktDecoder, PostgisWktDecoder
```
abstract class AbstractWktDecoder<T>
extends java.lang.Object
```
An abstract WKT decoder.
This class does not implement interface WktDecoder because it contains shared code to be used both in CrsWktDecoder and the Geometry WktDecoders.

AbstractWktDecoders are not thread-safe.
