Constructor Detail

CharBuffer

public CharBuffer(char[] chars)

Creates instance of CharBuffer already filled by chars.

Parameters:

bytes -

CharBuffer

public CharBuffer(int cacheSize)

Creates instance of CharBuffer with char array of required length.

Parameters:

cacheSize - length of char array

Method Detail

append

public CharBuffer append(char c)

Appends character to array chars if there are unfilled positions in it. Otherwise creates next link in the chain, and appends the character to it.

Parameters:

c -

Returns:

instance of CharBuffer to which character was appended.

append

public CharBuffer append(char[] cs,
                         int off,
                         int len)

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

Parameters:

c -

Returns:

instance of CharBuffer to which char array was appended.

getChars

public char[] getChars()

Returns stored char array.

Returns:

stored char array

getCharAt

public char getCharAt(int index)

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

Parameters:

index -

Returns:

getUsedSize

public int getUsedSize()

Returns actual number of characters stored in this link.

Returns:

getCacheSize

public int getCacheSize()

Returns capacity of this link.

Returns:

getTotalSize

public int getTotalSize()

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

Returns:

getPrevious

public CharBuffer getPrevious()

Returns the previous link in the chain.

Returns:

getNext

public CharBuffer getNext()

Returns the next link in the chain.

Returns:

setNext

public void setNext(CharBuffer b)

Sets the next link in the chain.

Parameters:

b -

toByteBuffer

public ByteBuffer toByteBuffer(String encoding)
                        throws UnsupportedEncodingException

Transforms this instance to instance of ByteBuffer (a link of chain of byte arrays).

Parameters:

encoding -

Returns:

link of chain of byte arrays

Throws:

UnsupportedEncodingException

toByteBuffer

public ByteBuffer toByteBuffer()

Transforms this instance to instance of ByteBuffer (a link of chain of byte arrays).

Returns:

link of chain of byte arrays

reset

public void reset()

Resets this char buffer to empty state
