## com.vividsolutions.jts.noding.snapround
Class GeometryNoder

    java.lang.Object
      com.vividsolutions.jts.noding.snapround.GeometryNoder

    public class GeometryNoder

extends java.lang.Object

Nodes the linework in a list of `Geometry`s using Snap-Rounding to a given `PrecisionModel`.

The input coordinates are expected to be rounded to the given precision model. This class does not perform that function. `GeometryPrecisionReducer` may be used to do this.

This class does not dissolve the output linework, so there may be duplicate linestrings in the output. Subsequent processing (e.g. polygonization) may require the linework to be unique. Using `UnaryUnion` is one way to do this (although this is an inefficient approach).

Constructor Summary
`GeometryNoder(PrecisionModel pm)` Creates a new noder which snap-rounds to a grid specified by the given `PrecisionModel`.

Method Summary
`java.util.List` | `node(java.util.Collection geoms)` Nodes the linework of a set of Geometrys using SnapRounding.
`void` | `setValidate(boolean isValidityChecked)` Sets whether noding validity is checked after noding is performed.

### GeometryNoder

    public GeometryNoder(PrecisionModel pm)

  Creates a new noder which snap-rounds to a grid specified by the given `PrecisionModel`.

  Parameters:
    `pm` - the precision model for the grid to snap-round to

Method Detail

### setValidate

    public void setValidate(boolean isValidityChecked)

  Sets whether noding validity is checked after noding is performed.

  Parameters:
    `isValidityChecked` -

### node

    public java.util.List node(java.util.Collection geoms)

  Nodes the linework of a set of Geometrys using SnapRounding.

  Parameters:
    `geoms` - a Collection of Geometrys of any type
  Returns:
    a List of LineStrings representing the noded linework of the input
