hasArray
public final boolean hasArray()
- Specified by:
hasArray
in interface NativeBuffer<B extends AbstractBuffer>
- Returns:
- true if this buffer has a primitive backup array, otherwise false
arrayOffset
public final int arrayOffset()
- Specified by:
arrayOffset
in interface NativeBuffer<B extends AbstractBuffer>
- Returns:
- the array offset of the optional primitive backup array of the buffer if
NativeBuffer.hasArray()
is true,
otherwise 0.
array
public Object array()

- Specified by:
array
in interface NativeBuffer<B extends AbstractBuffer>
- Returns:
- the primitive backup array of the buffer if

is true,
otherwise it throws UnsupportedOperationException
.
The returned primitive array maybe of type int[]
or long[]
, etc ..
- Throws:
UnsupportedOperationException
