Method Details

makeResettableChunk

public static <T,
ATTR_BASE extends Any>
ResettableObjectChunk<T,ATTR_BASE> makeResettableChunk()

makeResettableChunkForPool

public static <T,
ATTR_BASE extends Any>
ResettableObjectChunk<T,ATTR_BASE> makeResettableChunkForPool()

slice

public ResettableObjectChunk<T,ATTR_UPPER> slice(int offset,
 int capacity)

Description copied from interface: Chunk

Make a new Chunk that represents either exactly the same view on the underlying data as this Chunk, or a subrange of that view. The view is defined as [0..size) (in the coordinate space of this Chunk).

Specified by:

slice in interface Chunk<T>

Overrides:

slice in class ObjectChunk<T,ATTR_UPPER extends Any>

Parameters:

offset - Offset of the new Chunk, relative to this Chunk. 0 ≤ offset ≤ this.size

capacity - Capacity and initial size of the new Chunk. 0 ≤ capacity ≤ this.size - offset.

Returns:

The new Chunk. A new Chunk will always be returned, even if the Chunks represent the same view.

resetFromChunk

public <ATTR extends ATTR_UPPER>
ObjectChunk<T,ATTR> resetFromChunk(Chunk<? extends ATTR> other,
 int offset,
 int capacity)

Description copied from interface: ResettableReadOnlyChunk

Reset the data and bounds of this chunk to a range or sub-range of the specified Chunk.

Specified by:

resetFromChunk in interface ResettableReadOnlyChunk<T>

Parameters:

other - The other Chunk

offset - The offset into other

capacity - The capacity this should have after reset

resetFromArray

public <ATTR extends ATTR_UPPER>
ObjectChunk<T,ATTR> resetFromArray(Object array,
 int offset,
 int capacity)

Description copied from interface: ResettableChunk

Reset the data and bounds of this chunk to a range or sub-range of the specified array.

Specified by:

resetFromArray in interface ResettableChunk<T>

Specified by:

resetFromArray in interface ResettableReadOnlyChunk<T>

Parameters:

array - The array

offset - The offset into array

capacity - The capacity this should have after reset

Returns:

this

resetFromArray

public <ATTR extends ATTR_UPPER>
ObjectChunk<T,ATTR> resetFromArray(Object array)

Description copied from interface: ResettableChunk

Reset the data and bounds of this chunk to the entire range of the specified array.

Specified by:

resetFromArray in interface ResettableChunk<T>

Specified by:

resetFromArray in interface ResettableReadOnlyChunk<T>

Parameters:

array - The array

Returns:

this

clear

public <ATTR extends ATTR_UPPER>
ObjectChunk<T,ATTR> clear()

Description copied from interface: ResettableChunk

Reset this chunk to empty storage.

Specified by:

resetFromTypedChunk

public <ATTR extends ATTR_UPPER>
ObjectChunk<T,ATTR> resetFromTypedChunk(ObjectChunk<T,? extends ATTR> other,
 int offset,
 int capacity)

resetFromTypedArray
