Method Detail

close

public void close()

Specified by:

close in interface ASOutputStream

Overrides:

close in class ASOutFilter

getBufferWriter

public int getBufferWriter()

Returns:

the index of current write position.

getBufferEnd

public int getBufferEnd()

Returns:

the index of the end of the buffer.

getBufferCapacity

public int getBufferCapacity()

Returns:

the total capacity of buffer.

bufferSize

public int bufferSize()

Returns:

number of bytes actually present in the buffer.

storeChar

public void storeChar(byte b)

Stores character to current writer position and increments writer position. For better performance does not check buffer overflow, use with care.

Parameters:

b - is character to be put into buffer.

bufferRewind

public int bufferRewind(int offset)

Moves buffer writer pointer back by given number of bytes.

Parameters:

offset - is number of bytes on which we should move pointer.

Returns:

actual amount of bytes on which pointer was moved.
