Interface FeatureStoreTransforms

All Superinterfaces:

Cloneable

All Known Implementing Classes:

DefaultFeatureStoreTransforms, FeatureTypeManager.FeatureTypeManagerFeatureStoreTransforms

public interface FeatureStoreTransforms
extends Cloneable

This interface represents a container for store transforms. Provides access to transforms by index and by iterator, and also allows adding and removing transforms.

Method Summary

Methods

Modifier and Type	Method and Description
FeatureStoreTransform	add(FeatureStoreTransform transform) Adds a FeatureStoreTransform to this container.
void	clear() Empties this container.
FeatureStoreTransform	getTransform(int index) Returns the FeatureStoreTransform given its index.
boolean	isEmpty() Indicates whether this container is empty.
boolean	isTransformsOriginalValues() Retruns true if any FeatureStoreTransform make changes of any previous attributes values.
Iterator	iterator() Returns an iterator over this container elements.
boolean	remove(FeatureStoreTransform transform) Removes the given FeatureStoreTransform.
Object	remove(int index) Removes the FeatureStoreTransform given its index.

Method Detail

getTransform

FeatureStoreTransform getTransform(int index)

Returns the FeatureStoreTransform given its index.

Parameters:

index - a position in this FeatureStoreTransforms

Returns:

the FeatureStoreTransform that is stored in the given index.

add

FeatureStoreTransform add(FeatureStoreTransform transform)
                          throws DataException

Adds a FeatureStoreTransform to this container.

Parameters:

transform - the FeatureStoreTransform to add

Returns:

the added FeatureStoreTransform

Throws:

DataException

size

int size()

Returns the number of FeatureStoreTransforms stored in this container

Returns:

number of FeatureStoreTransforms stored in this container

isEmpty

boolean isEmpty()

Indicates whether this container is empty.

Returns:

true if this container is empty, false if not

iterator

Iterator iterator()

Returns an iterator over this container elements.

Returns:

an iterator over this container elements.

clear

void clear()

Empties this container.

remove

Object remove(int index)

Removes the FeatureStoreTransform given its index.

Parameters:

index - the position of the FeatureStoreTransform to remove.

Returns:

the removed object

remove

boolean remove(FeatureStoreTransform transform)

Removes the given FeatureStoreTransform.

Parameters:

transform - FeatureStoreTransform to remove

Returns:

true if the transform was successfully removed, false if not.

isTransformsOriginalValues

boolean isTransformsOriginalValues()

Retruns true if any FeatureStoreTransform make changes of any previous attributes values.
If all FeatureStoreTransform affects only to attributes defition, the FeatureSet performance can be better.

Returns:
