Constructor Details

AbstractByteBufferCombinerInPlace

protected AbstractByteBufferCombinerInPlace(Class<?> elementType,
 ByteBuffer workStorageForOneElement,
 MemoryModel memoryModel)

Creates a new instance of this combiner.

Parameters:

elementType - the type of elements of the combined array.

workStorageForOneElement - a little ByteBuffer enough to store one element of the combined array. May be direct ByteBuffer, but the heap one usually provides better performance.

memoryModel - the memory model which will be used for creating combined arrays.

Throws:

NullPointerException - if one of the arguments is null.

IllegalArgumentException - if the passed ByteBuffer is read-only.

Method Details

allocateElement

public abstract E allocateElement()

Description copied from interface: CombinedMemoryModel.CombinerInPlace

Creates a new element that can be stored in or loaded from the combined array. Never returns null.

Specified by:

allocateElement in interface CombinedMemoryModel.CombinerInPlace<E>

Returns:

some instance of an element of the combined array.

loadElementInPlace

protected abstract void loadElementInPlace(E resultElement)

Should fill the passed element of the combined array from CombinedMemoryModel.AbstractByteBufferCombiner.workStorage.

Parameters:

resultElement - the object where the retrieved content will be stored.

Throws:

NullPointerException - if the argument is null.

getInPlace

public final void getInPlace(long index,
 E resultValue,
 Array[] storage)

Description copied from interface: CombinedMemoryModel.CombinerInPlace

Loads an element #index of the combined array from the given set of arrays into resultValue object. This method is called by ObjectInPlaceArray.getInPlace(long, Object) method.

Specified by:

getInPlace in interface CombinedMemoryModel.CombinerInPlace<E>

Parameters:

index - an index in the combined array.

resultValue - the object where the retrieved content will be stored.

storage - a set of arrays where the retrieved content is stored now.
