                    FeatureQuery query,
                    FeatureType featureType)

Parameters:

store - Source of this feature set

query - Query

featureType - Featuretype requested

Method Detail

canFilter

public boolean canFilter()

Specified by:

canFilter in interface FeatureSetProvider

canOrder

public boolean canOrder()

Specified by:

canOrder in interface FeatureSetProvider

canIterateFromIndex

public boolean canIterateFromIndex()

Specified by:

canIterateFromIndex in interface FeatureSetProvider

getSize

public long getSize()
             throws DataException

Specified by:

getSize in interface FeatureSetProvider

Throws:

DataException

isEmpty

public boolean isEmpty()
                throws DataException

Specified by:

isEmpty in interface FeatureSetProvider

Throws:

DataException

createIterator

protected AbstractFeatureProviderIterator createIterator(long index)
                                                  throws DataException

Description copied from class: AbstractFeatureSetProvider

Creates a new Iterator, begginning at the specified data index.

Specified by:

createIterator in class AbstractFeatureSetProvider

Parameters:

index - the first element position to be returned by the Iterator

Returns:

a new Iterator

Throws:

DataException - if there is an error creating the Iterator

createFastIterator

protected AbstractFeatureProviderIterator createFastIterator(long index)
                                                      throws DataException

Description copied from class: AbstractFeatureSetProvider

Creates a new fast Iterator, begginning at the specified data index. By fast this means the object instances of data ( FeatureProvider) may be reused between the Iterator.next() method invocations.

Specified by:

createFastIterator in class AbstractFeatureSetProvider

Parameters:

index - the first element position to be returned by the Iterator

Returns:

a new Iterator

Throws:

DataException - if there is an error creating the Iterator

doDispose

protected void doDispose()
                  throws BaseException

Description copied from class: AbstractDisposable

Internal implementation for the AbstractDisposable.dispose() method, to be implemented by child classes.

Specified by:

doDispose in class AbstractDisposable

Throws:

BaseException

AbstractDisposable.dispose()

closeResourceRequested

public boolean closeResourceRequested(ResourceProvider resource)

Specified by:

closeResourceRequested in interface ResourceConsumer

resourceChanged

public void resourceChanged(ResourceProvider resource)

Specified by:

resourceChanged in interface ResourceConsumer
