Class WKBReader

    java.lang.Object
      com.vividsolutions.jts.io.WKBReader

public class WKBReader
extends java.lang.Object

Reads a `Geometry`from a byte stream in Well-Known Binary format. Supports use of an `InStream`, which allows easy use with arbitary byte stream sources.

This class reads the format describe in `WKBWriter`. It also partiually handles the Extended WKB format used by PostGIS (by reading SRID values)

This class is designed to support reuse of a single instance to read multiple geometries. This class is not thread-safe; each thread should create its own instance.

Method Summary
`static byte[]` | `hexToBytes(java.lang.String hex)` Converts a hexadecimal string to a byte array.
`Geometry` | `read(byte[] bytes)` Reads a single `Geometry` from a byte array.
`Geometry` | `read(InStream is)` Reads a `Geometry` from an {@link InStream).
