public class LinearComponentExtracter
extends java.lang.Object
implements GeometryComponentFilter

Extracts all the 1-dimensional (`LineString`) components from a `Geometry`.

Version:
  1.7

Constructor Summary
`LinearComponentExtracter(java.util.Collection lines)` Constructs a LineExtracterFilter with a list in which to store LineStrings found.

### LinearComponentExtracter

    public LinearComponentExtracter(java.util.Collection lines,
                                    boolean isForcedToLineString)

  Constructs a LineExtracterFilter with a list in which to store LineStrings found.

Method Detail

### getLines

    public static java.util.Collection getLines(java.util.Collection geoms,
                                                java.util.Collection lines)

  Extracts the linear components from a single `Geometry` and adds them to the provided `Collection`.

  Parameters:
    `geoms` - the Collection of geometries from which to extract linear components
    `lines` - the collection to add the extracted linear components to
  Returns:
    the collection of linear components (LineStrings or LinearRings)

### getLines

    public static java.util.Collection getLines(java.util.Collection geoms,
                                                java.util.Collection lines,
                                                boolean forceToLineString)

  Extracts the linear components from a single `Geometry` and adds them to the provided `Collection`.

  Parameters:
    `geoms` - the Collection of geometries from which to extract linear components
    `lines` - the collection to add the extracted linear components to
  Returns:
    the collection of linear components (LineStrings or LinearRings)

### getLines

    public static java.util.Collection getLines(Geometry geom,
                                                java.util.Collection lines)

  Extracts the linear components from a single `Geometry` and adds them to the provided `Collection`.

  Parameters:
    `geom` - the geometry from which to extract linear components
    `lines` - the Collection to add the extracted linear components to
  Returns:
    the Collection of linear components (LineStrings or LinearRings)

### getLines

    public static java.util.Collection getLines(Geometry geom,
                                                java.util.Collection lines,
                                                boolean forceToLineString)

  Extracts the linear components from a single `Geometry` and adds them to the provided `Collection`.

  Parameters:
    `geom` - the geometry from which to extract linear components
    `lines` - the Collection to add the extracted linear components to
  Returns:
    the Collection of linear components (LineStrings or LinearRings)

### getLines

    public static java.util.List getLines(Geometry geom)

  Extracts the linear components from a single geometry. If more than one geometry is to be processed, it is more efficient to create a single `LineExtracterFilter` instance and pass it to multiple geometries.

  Parameters:
    `geom` - the geometry from which to extract linear components
  Returns:
    the list of linear components

### setForceToLineString

    public void setForceToLineString(boolean isForcedToLineString)

### filter

    public void filter(Geometry geom)

  Description copied from interface: `GeometryComponentFilter`
  Performs an operation with or on `geom`.

  Specified by:
    `filter` in interface `GeometryComponentFilter`
  Parameters:
    `geom` - a `Geometry` to which the filter is applied.
