ByteArrayOutputStream2

public ByteArrayOutputStream2(byte[] buffer)

Method Detail

write

public void write(int b)

write given byte to buffer.

Parameters:

b - byte to write

Throws:

java.lang.ArrayIndexOutOfBoundsException - if new byte count would exceed length of buffer after this operation

write

public void write(int b,
                  int mask)

combine (OR) current value with given byte using supplied mask. resulting value is (b & mask) | (currentValue & ~mask)

Parameters:

b - byte to combine

mask - 8 bit mask

Throws:

java.lang.ArrayIndexOutOfBoundsException

write

public void write(byte[] b,
                  int off,
                  int len)

Writes bytes from the specified byte array to buffer

Parameters:

b - byte array

off - start offset

len - number of bytes to write

Throws:

java.lang.ArrayIndexOutOfBoundsException - if new byte count would exceed length of buffer after this operation (however the max possible byte count is written first)

getCount

public int getCount()

skip

public int skip(int n)

Skip some bytes. Negative skip is possible.

Parameters:

n - byte count to skip

Returns:

how much bytes were skipped

seek

public void seek(int pos)
