Constructor Detail

AbstractByteSequence.AggregateByteSequence

public AbstractByteSequence.AggregateByteSequence(ByteSequence seqFirst,
                                                  ByteSequence seqSecond)

Construct an AggregateByteSequence from two ByteSequence objects.

Parameters:

seqFirst - the first ByteSequence

seqSecond - the second ByteSequence

Method Detail

length

public int length()

Determine the number of bytes of data represented by this ByteSequence.

Returns:

the number of bytes represented by this Node

byteAt

public byte byteAt(int of)

Determine the n-th byte of the byte sequence.

Parameters:

of - the zero-based byte offset within the sequence of bytes (0 <= of < ByteSequence.length())

Returns:

the byte at the specified offset

subSequence

public ByteSequence subSequence(int ofStart,
                                int ofEnd)

Returns a new ByteSequence that is a subsequence of this sequence. The subsequence starts with the byte value at the specified index and ends with the byte value at index ofEnd - 1. The length (in bytes) of the returned sequence is ofEnd - ofStart, so if ofStart == ofEnd then an empty sequence is returned.

Specified by:

subSequence in interface ByteSequence

Overrides:

subSequence in class AbstractByteSequence

Parameters:

ofStart - the start index, inclusive

ofEnd - the end index, exclusive

Returns:

the specified subsequence
