Method Detail

equals

public boolean equals(java.lang.Object other)

checks if this point is completly equal to the submitted geometry

Overrides:

equals in class GM_Object_Impl

Parameters:

other - the GM_Object to test for equality

Returns:

true if the objects are equal, else false

getDimension

public int getDimension()

The operation "dimension" shall return the inherent dimension of this GM_Object, which shall be less than or equal to the coordinate dimension. The dimension of a collection of geometric objects shall be the largest dimension of any of its pieces. Points are 0-dimensional, curves are 1-dimensional, surfaces are 2-dimensional, and solids are 3-dimensional.

Specified by:

getDimension in interface GM_Object

getCoordinateDimension

public int getCoordinateDimension()

The operation "coordinateDimension" shall return the dimension of the coordinates that define this GM_Object, which must be the same as the coordinate dimension of the coordinate reference system for this GM_Object.

Specified by:

getCoordinateDimension in interface GM_Object

clone

public java.lang.Object clone()

returns a shallow copy of the geometry.

Overrides:

clone in class GM_Object_Impl

getX

public double getX()

returns the x-value of this point

Specified by:

getX in interface GM_Point

getY

public double getY()

returns the y-value of this point

Specified by:

getY in interface GM_Point

getZ

public double getZ()

returns the y-value of this point

Specified by:

getZ in interface GM_Point

getAsArray

public double[] getAsArray()

returns the x- and y-value of the point as a two dimensional array the first field contains the x- the second field the y-value.

Specified by:

getAsArray in interface GM_Point

translate

public void translate(double[] d)

translate the point by the submitted values. the dz- value will be ignored.

Specified by:

translate in interface GM_Object

getPosition

public GM_Position getPosition()

Description copied from interface: GM_Point

returns the position of the point

Specified by:

getPosition in interface GM_Point

Returns:

intersects

public boolean intersects(GM_Object gmo)

The Boolean valued operation "intersects" shall return TRUE if this GM_Object intersects another GM_Object. Within a GM_Complex, the GM_Primitives do not intersect one another. In general, topologically structured data uses shared geometric objects to capture intersection information.
