Method Detail

getSourceDimensions

default int getSourceDimensions()

Gets the dimension of input points.

Specified by:

getSourceDimensions in interface org.opengis.referencing.operation.MathTransform

Returns:

The dimension of input points.

getTargetDimensions

default int getTargetDimensions()

Gets the dimension of output points.

Specified by:

getTargetDimensions in interface org.opengis.referencing.operation.MathTransform

Returns:

The dimension of output points.

transform

default com.vividsolutions.jts.geom.Geometry transform(com.vividsolutions.jts.geom.Geometry geometry)
                                                throws org.opengis.referencing.operation.TransformException

Transforms the specified geometry.

Parameters:

geometry - the geometry to be transformed.

Returns:

the transformed geometry.

Throws:

org.opengis.referencing.operation.TransformException - if the geometry can't be transformed.

inverse

MathTransform2D inverse()
                 throws org.opengis.referencing.operation.NoninvertibleTransformException

Creates the inverse transform of this object.

Specified by:

inverse in interface org.opengis.referencing.operation.MathTransform

Specified by:

inverse in interface org.opengis.referencing.operation.MathTransform2D

Returns:

The inverse transform.

Throws:

org.opengis.referencing.operation.NoninvertibleTransformException - if the transform can't be inversed.

equals

boolean equals(Object object)

Indicates whether some other object is "equal to" this one.

The equals method implements an equivalence relation on non-null object references:

• It is reflexive: for any non-null reference value x, x.equals(x) should return true.
• It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
• It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
• For any non-null reference value x, x.equals(null) should return false.

The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).

Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.

Overrides:

equals in class Object

Parameters:

object - the reference object with which to compare.

Returns:

true if this object is the same as the obj argument; false otherwise.

hashCode(), HashMap

hashCode

int hashCode()

Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.

The general contract of hashCode is:

• Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
• If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
• It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)

Overrides:

hashCode in class Object

Returns:

a hash code value for this object.
