Package org.apache.sis.referencing.operation.builder

Class LinearTransformBuilder.Ungridded

java.lang.Object

org.apache.sis.internal.util.AbstractMap<org.opengis.geometry.DirectPosition,org.opengis.geometry.DirectPosition>

org.apache.sis.referencing.operation.builder.LinearTransformBuilder.ControlPoints

org.apache.sis.referencing.operation.builder.LinearTransformBuilder.Ungridded

All Implemented Interfaces:

Map<org.opengis.geometry.DirectPosition,org.opengis.geometry.DirectPosition>

Enclosing class:

LinearTransformBuilder

private final class LinearTransformBuilder.Ungridded
extends LinearTransformBuilder.ControlPoints

Implementation of the map returned by LinearTransformBuilder.getControlPoints() when no grid is used. This implementation is simpler than the gridded case, but less efficient as some methods require a linear scan.

Method Details

isEmpty

public boolean isEmpty()

Overrides default method with more efficient implementation.

Specified by:

isEmpty in interface Map<org.opengis.geometry.DirectPosition,org.opengis.geometry.DirectPosition>

Overrides:

isEmpty in class AbstractMap<org.opengis.geometry.DirectPosition,org.opengis.geometry.DirectPosition>

Returns:

true if this map contains no element.

size

public int size()

Description copied from class: AbstractMap

Returns the number of key-value mappings in this map. The default implementation count the number of values returned by AbstractMap.entryIterator(). Subclasses should implement a more efficient method.

Specified by:

size in interface Map<org.opengis.geometry.DirectPosition,org.opengis.geometry.DirectPosition>

Overrides:

size in class AbstractMap<org.opengis.geometry.DirectPosition,org.opengis.geometry.DirectPosition>

domain

int domain()

Description copied from class: LinearTransformBuilder.ControlPoints

Returns the number of points to consider when searching in LinearTransformBuilder.sources or LinearTransformBuilder.targets arrays. For gridded data we cannot rely on LinearTransformBuilder.numPoints because the coordinate values may be at any index, not necessarily at consecutive indices.

Overrides:

domain in class LinearTransformBuilder.ControlPoints

flatIndex

int flatIndex(org.opengis.geometry.DirectPosition source)

Returns the index where to fetch a target position for the given source position in the flattened array. In non-gridded case, this operation requires linear scan.

Overrides:

flatIndex in class LinearTransformBuilder.ControlPoints

See Also:

• LinearTransformBuilder.flatIndex(DirectPosition)

entryIterator

protected AbstractMap.EntryIterator<org.opengis.geometry.DirectPosition,org.opengis.geometry.DirectPosition> entryIterator()

Returns an iterator over the entries. DirectPosition instances are created on-the-fly during the iteration.

Overrides:

entryIterator in class LinearTransformBuilder.ControlPoints

Returns:

an iterator over the entries in this map, or null.
