Enclosing class:

SpecializableTransform

private static final class SpecializableTransform.SubArea
extends RTreeNode

The region where a transform is valid, together with the transform. Contains also a chain of SubAreas fully included in this area. Shall be unmodified after SpecializableTransform construction.

Field Details

serialVersionUID

private static final long serialVersionUID

For cross-version compatibility.

• Constant Field Values

transform

final org.opengis.referencing.operation.MathTransform transform

The transform to apply in this area.

inverse

org.opengis.referencing.operation.MathTransform inverse

The inverse of the transform, computed when first needed. Synchronization for multi-threading is done (indirectly) in SpecializableTransform.inverse().

• createInverseTransform()

Constructor Details

SubArea

SubArea(org.opengis.geometry.Envelope area,
 org.opengis.referencing.operation.MathTransform transform)

Creates a new area where a transform is valid.

Method Details

createInverseTransform

final void createInverseTransform()
                           throws org.opengis.referencing.operation.NoninvertibleTransformException

Creates the inverse transforms. This method should be invoked only once when first needed in a block synchronized (indirectly) by SpecializableTransform.inverse().

Throws:

org.opengis.referencing.operation.NoninvertibleTransformException

format

final void format(Formatter formatter)

Formats this area and its transform as a pseudo-WKT. For SpecializableTransform.formatTo(Formatter) implementation only.

hashCode

public int hashCode()

For SpecializableTransform.computeHashCode() implementation.

Overrides:

hashCode in class RTreeNode

Returns:

a hash code value for this node and its children.

equals

public boolean equals(Object obj)

For AbstractMathTransform.equals(Object) implementation.

Overrides:

equals in class RTreeNode

Parameters:

obj - the object to compare with this node.

Returns:

whether the two objects are of the same class, have equal envelope and equal children list.
