Constructor Detail

MultiMLineString

public MultiMLineString(MLineString[] MlineStrings,
                        double mGap,
                        com.vividsolutions.jts.geom.GeometryFactory factory)

Parameters:

MlineStrings - the MLineStrings for this MultiMLineString, or null or an empty array to create the empty geometry. Elements may be empty LineStrings, but not nulls.

Method Detail

getGeometryType

public java.lang.String getGeometryType()

Overrides:

getGeometryType in class com.vividsolutions.jts.geom.MultiLineString

getMGap

public double getMGap()

getMatCoordinate

public double getMatCoordinate(com.vividsolutions.jts.geom.Coordinate co,
                               double tolerance)
                        throws MGeometryException

Description copied from interface: MGeometry

Returns the measure value at the Coordinate

Specified by:

getMatCoordinate in interface MGeometry

Parameters:

co - the Coordinate for which the measure value is sought

tolerance - distance to the MGeometry within which Coordinate c has to lie

Returns:

the measure value if Coordinate c is within tolerance of the Geometry, else Double.NaN

When the geometry is a ring or is self-intersecting more coordinates may be determined by one coordinate. In that case, the lowest measure is returned.

Throws:

MGeometryException - when this MGeometry is not monotone

clone

public java.lang.Object clone()

Overrides:

clone in class com.vividsolutions.jts.geom.GeometryCollection

measureOnLength

public void measureOnLength(boolean keepBeginMeasure)

Description copied from interface: MGeometry

Builds measures along the Geometry based on the length from the beginning (first coordinate) of the Geometry.

Specified by:

measureOnLength in interface MGeometry

Parameters:

keepBeginMeasure - - if true, the measure of the first coordinate is maintained and used as start value, unless this measure is Double.NaN

getCoordinateAtM

public com.vividsolutions.jts.geom.Coordinate getCoordinateAtM(double m)
                                                        throws MGeometryException

Description copied from interface: MGeometry

Returns the Coordinate along the Geometry at the measure value

Specified by:

getCoordinateAtM in interface MGeometry

Parameters:

m - measure value

Returns:

the Coordinate if m is on the MGeometry otherwise null

Throws:

MGeometryException - when MGeometry is not monotone

getCoordinatesBetween

public com.vividsolutions.jts.geom.CoordinateSequence[] getCoordinatesBetween(double begin,
                                                                              double end)
                                                                       throws MGeometryException

Description copied from interface: MGeometry

Returns the coordinatesequence(s) containing all coordinates between the begin and end measures.

Specified by:

getCoordinatesBetween in interface MGeometry

Parameters:

begin - begin measure

end - end measure

Returns:

an array containing all coordinatesequences in order between begin and end. Each CoordinateSequence covers a contiguous stretch of the MGeometry.

Throws:

MGeometryException - when this MGeometry is not monotone

getMinM

public double getMinM()

Description copied from interface: MGeometry

Returns the minimum M-value of the MGeometry

Specified by:

getMinM in interface MGeometry

Returns:

the minimum M-value

getMaxM

public double getMaxM()

Description copied from interface: MGeometry

Returns the maximum M-value of the MGeometry

Specified by:

getMaxM in interface MGeometry

Returns:

the maximum M-value

isMonotone

public boolean isMonotone(boolean strictMonotone)

Description copied from interface: MGeometry

Determine whether the LRS measures (not the x,y,z coordinates) in the Coordinate sequence of the geometry is Monotone. Monotone implies that all measures in a sequence of coordinates are consecutively increasing, decreasing or equal according to the definition of the implementing geometry. Monotonicity is a pre-condition for most operations on MGeometries. The following are examples on Monotone measure sequences on a line string:

• [0,1,2,3,4] - Monotone Increasing
• [4,3,2,1] - Monotone Decreasing
• [0,1,1,2,3] - Non-strict Monotone Increasing
• [5,3,3,0] - Non-strict Monotone Decreasing

Specified by:

isMonotone in interface MGeometry

Returns:

true if the coordinates in the CoordinateSequence of the geometry are monotone.

asGeometry

public com.vividsolutions.jts.geom.Geometry asGeometry()

Description copied from interface: MGeometry

Returns this MGeometry as a Geometry.

Modifying the returned Geometry will result in internal state changes.

Specified by:

asGeometry in interface MGeometry

Returns:

this object as a Geometry.
