Classes

BinaryCodec

A binary shape format. It is not designed to be a published standard, unlike Well Known Binary (WKB). The initial release is simple but it could get more optimized to use fewer bytes or to write & read pre-computed index structures.

Immutable and thread-safe.

LegacyShapeReadWriterFormat

Reads & writes a shape from a given string in the old format.

ParseUtils

Utility methods related to parsing a series of numbers.

This code came from DistanceUtils, which came from Apache Lucene, LUCENE-773, which in turn came from "LocalLucene".

WktShapeParser

An extensible parser for Well Known Text (WKT). The shapes supported by this class are:

'EMPTY' is supported. Specifying 'Z', 'M', or any other dimensionality in the WKT is effectively ignored. Thus, you can specify any number of numbers in the coordinate points but only the first two take effect. The docs for the parse___Shape methods further describe these shapes, or you

Most users of this class will call just one method: Parse(String), or ParseIfSupported(String) to not fail if it isn't parse-able.

To support more shapes, extend this class and override ParseShapeByType(WktShapeParser.State, String). It's also possible to delegate to a WKTParser by also delegating NewState(String).

Note, instances of this base class are threadsafe.

WktShapeParser.State

The parse state.
