A simple WKT (Well Know Text) parser grammar written for JavaCC.

The goal was to use it in a jEdit plugin, but you can use it for any other purpose

It does not support all WKT syntax but might be extended in the future.

## Dependency

Available through Maven central

```xml

  com.kpouer

  wktparser

  1.1.1

```

## Supported structures

* POINT

* LINESTRING

* POLYGON

* MULTIPOINT

* MULTIPOLYGON

* MULTILINESTRING

* GEOMETRYCOLLECTION

## Example

```java

Start start = new WKT(new StringReader("LINESTRING(30 10,-3.2011243453   -101.12124240)"))

    .Start();

LineString linestring = (LineString) start.jjtGetChild(0);

Point point1 = (Point) linestring.jjtGetChild(0);

Point point2 = (Point) linestring.jjtGetChild(1);

```

By default the parser will use JJT tree classes. But you could also use the shapes from

com.kpouer.wkt.shape package that implements shapes using double values.

```java

Polygon polygon = WKT.parseShape("POLYGON((40 40, 20 45, 45 30, 40 40))");

```
