Parameters:

size - the size of the input buffer.

BytesInputStream

public BytesInputStream(byte[] data)

Constructs a new BytesInputStream instance, that will read from the given data.

Parameters:

data - a byte array containing data to be read.

Method Detail

reset

public void reset(byte[] data)

Parameters:

data - a byte array with data to be read.

reset

public void reset(byte[] data,
                  int length)

Resets this BytesInputStream using the given byte[] as new input buffer and a given length.

Parameters:

data - a byte array with data to be read.

length - the length of the buffer to be considered.

reset

public void reset(int length)

Resets this BytesInputStream assigning the input buffer a new length.

Parameters:

length - the length of the buffer to be considered.
