wrap

public static BufferVault wrap(byte[] byteArrayToHeapByteBuffer)

Short end for ByteBuffer.wrap and BufferVault.wrap(ByteBuffer)

Parameters:

byteArrayToHeaByteBuffer -

Returns:

ensureBufferSize

public BufferVault ensureBufferSize(int itemsCountToAdd)

clear

public void clear()

write

public BufferVault write(ByteBuffer buffer)

Returns:

this

write

public BufferVault write(byte[] buffer,
                         int pos,
                         int len)

Returns:

this

write

public BufferVault write(byte[] buffer)

Returns:

this

getSize

public int getSize()

readAll

public byte[] readAll()

Returns:

empty if not datas to read.

read

public int read(byte[] b,
                int pos,
                int off,
                int len)

Parameters:

b - the array to feed with datas

pos - where start to read data in internal array

off - where to put data in b

len - max data len to put in b

Returns:

real data len readed from internal array, -1 no datas/pos to big

read

Returns:

empty if not datas to read.

iterator

public Iterator<byte[]> iterator(int bufferSize)

Internal buffer will be reused for each next

stream

read

public BufferVault read(OutputStream outStream)
                 throws IOException

Don't close/flush after write. Inject direcly the internal byte array. If outStream change it, it will change internally.

Returns:

this

Throws:

IOException

write

                 int bufferSize)
          throws IOException

Don't close/flush after read, call available before start read to pre-heat internal buffer

Parameters:

inStream -

Returns:

total transferred bytes

Throws:

IOException

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

compactAndAppend

public void compactAndAppend(int pos,
                             BufferVault inserted)

Remove all internal datas betwen 0 and pos, add append (copy/write) newDataSource content.
