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

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

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
