Constructor Detail

BytesInputStream

public BytesInputStream(int size)

Constructs a new BytesInputStream instance, with an empty buffer of a given size.

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)

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

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.

skip

public int skip(int n)

Skips the given number of bytes or all bytes till the end of the assigned input buffer length.

Parameters:

n - the number of bytes to be skipped as int.

Returns:

the number of bytes skipped.

getBuffer

public byte[] getBuffer()

Returns the reference to the input buffer.

Returns:
