Constructor Detail

ByteSequence

public ByteSequence(byte[] buff)

Allocates a new ByteSequence so that it represents the sequence of bytes currently contained in the byte array argument. The contents of the byte array are not copied;

Parameters:

buff - value of the bytesequence

ByteSequence

public ByteSequence(byte[] buff,
                    int offset,
                    int length)

Allocates a new ByteSequence that contains characters from a subarray of the byte array argument. The offset argument is the index of the first byte of the subarray and the length argument specifies the length of the subarray. The contents of the subarray are not copied;

Parameters:

buff - Array that is the source of bytes

offset - The initial offset

length - The length

Throws:

IndexOutOfBoundsException - If the offset and length arguments index bytes outside the bounds of the buff array

Method Detail

set

public void set(byte[] buff,
                int offset,
                int length)

replaces the internal byte buffer with the given byte array.

Parameters:

buff - Array that is the source of bytes

offset - The initial offset

length - The length
