Constructor Detail

ByteBuffer

public ByteBuffer(byte[] bytes)

Creates instance of ByteBuffer already filled by bytes.

Parameters:

bytes -

ByteBuffer

public ByteBuffer(int cacheSize)

Creates instance of ByteBuffer with byte array of required length.

Parameters:

cacheSize - length of byte array

Method Detail

append

public ByteBuffer append(byte c)

Appends byte to array if there are unfilled positions in it. Otherwize creates next link in the chain, and appends the byte to it.

Parameters:

c -

Returns:

instance of ByteBuffer to which byte was appended.

append

public ByteBuffer append(byte[] bs,
                int off,
                int len)

Appends segment of a byte array to array if there are unfilled positions in it. Otherwize creates next link in the chain, and appends data to it.

Parameters:

bs -

off -

len -

Returns:

instance of ByteBuffer to which byte array was appended.

getBytes

public byte[] getBytes()

Returns stored byte array.

Returns:

stored byte array

getByteAt

public byte getByteAt(int index)

Returns byte at index. No check is fulfilled to provide high speed.

Parameters:

index -

Returns:

byte at index

getUsedSize

public int getUsedSize()

Returns actual number of byte stored in this link.

Returns:

actual number of byte stored in this link

getCacheSize

public int getCacheSize()

Returns capacity of this link.

Returns:

capacity of this link

getTotalSize

public int getTotalSize()

Returns total number of bytes stored in this link and all its predecessors.

Returns:

total number of bytes stored in this link and all its predecessors

getPrevious

public ByteBuffer getPrevious()

Returns the previous link in the chain.

Returns:

the previous link in the chain

getNext

public ByteBuffer getNext()

Returns the next link in the chain.

Returns:

the next link in the chain

setNext

public void setNext(ByteBuffer b)

Sets the next link in the chain.

Parameters:

b -

toCharBuffer

public CharBuffer toCharBuffer(String encoding)
                        throws UnsupportedEncodingException

Transforms this instance to instance of CharBuffer (a link of chain of char arrays).

Parameters:

encoding -

Returns:

link of chain of char arrays
