Constructor Detail

UnguardedPagedStorageImpl

public UnguardedPagedStorageImpl(ImmutableList<ImmutableList<T>> pages)

Construct new immutable reference from prepared storage.

Parameters:

pages - Non empty list of non empty pages. All but the last page are expected to be the same sized.

Method Detail

size

public int size()

Description copied from interface: UnguardedPagedStorage

Total number of descriptors stored.

Specified by:

size in interface UnguardedPagedStorage<T extends Serializable>

Returns:

Size

traverse

public void traverse(UnguardedVisitor<T> visitor,
                     SubProgressObserver po)

Description copied from interface: UnguardedPagedStorage

Traverse storage on single thread. Iterate over pages/descriptors and invoke the supplied callback.

Note that the callback must not modify passed descriptors.

Specified by:

traverse in interface UnguardedPagedStorage<T extends Serializable>

Parameters:

visitor - Callback to invoke

po - ProgressObserver to track progress. Upon completion ProgressObserver.done() will be invoked.

iterateDescriptors

public UnmodifiableIterator<T> iterateDescriptors()

Description copied from interface: UnguardedPagedStorage

Iterate descriptors.

Specified by:

iterateDescriptors in interface UnguardedPagedStorage<T extends Serializable>

Returns:

Iterator for stored descriptors

iterateDescriptorPages

public UnmodifiableIterator<ImmutableList<T>> iterateDescriptorPages(int pagesize)

Description copied from interface: UnguardedPagedStorage

Iterate descriptor pages. Descriptors will be repackaged into new pages.

Specified by:

iterateDescriptorPages in interface UnguardedPagedStorage<T extends Serializable>

Parameters:

pagesize - Number of descriptors to page together

Returns:

Iterator of descriptor lists

iterateDescriptorPages

public UnmodifiableIterator<ImmutableList<T>> iterateDescriptorPages()

Description copied from interface: UnguardedPagedStorage

Iterate descriptor pages. Use representation specific page size.

Specified by:

iterateDescriptorPages in interface UnguardedPagedStorage<T extends Serializable>

Returns:

Iterator of descriptor lists

getUnguardedDescriptor

public T getUnguardedDescriptor(int index)

Description copied from interface: UnguardedPagedStorage

Retrieve a descriptor.

Specified by:

getUnguardedDescriptor in interface UnguardedPagedStorage<T extends Serializable>

Parameters:

index - Descriptor index

Returns:

Unguarded descriptor

getDescriptorAsString

public String getDescriptorAsString(int index,
                                    boolean recognizeArrays)

Description copied from interface: UnguardedPagedStorage

Retrieve descriptor as String.

This operation is recommended for debug only. Execution might be slow.

Specified by:

getDescriptorAsString in interface UnguardedPagedStorage<T extends Serializable>

Parameters:

index - Index of descriptor

recognizeArrays - Recognize arrays and traverse its elements

Returns:

Descriptor as String
