ByteStringBuffer

public ByteStringBuffer()

ByteStringBuffer

public ByteStringBuffer(int length)

Parameters:

length -

Method Detail

byteAt

public byte byteAt(int index)

Description copied from interface: ByteSequence

Returns the byte at the specified index. An index ranges from zero to length() - 1. The first byte of the sequence is at index zero, the next at index one, and so on, as for array indexing.

Specified by:

byteAt in interface ByteSequence

Parameters:

index - the index of the character to be returned

Returns:

the specified byte

length

public int length()

Description copied from interface: ByteSequence

Returns the length of this byte sequence. The length is the number of bytes in the sequence.

Specified by:

length in interface ByteSequence

Returns:

the number of bytes in this sequence

subSequence

public ByteSequence subSequence(int start,
                                int end)

Description copied from interface: ByteSequence

Returns a new byte sequence that is a subsequence of this sequence. The subsequence starts with the byte at the specified index and ends with the byte at index end - 1. The length of the returned sequence is end - start, so if start == end then an empty sequence is returned.

Specified by:

subSequence in interface ByteSequence

Parameters:

start - the start index, inclusive

end - the end index, exclusive

Returns:

the specified subsequence

substring

public ByteString substring(int begin,
                            int end)

Parameters:

begin - the first byte index to include in the substring

end - the last byte index to include in the substring

Returns:

substring of this byte string from begin to end

getBytes

public void getBytes(int srcBegin,
                     int srcEnd,
                     byte[] dst,
                     int dstBegin)

Description copied from interface: ByteSequence

Returns a byte array containing the bytes in this sequence in the same order as this sequence and within the bounds given. The length of the byte array will be equal to srcEnd - srcBegin + 1.

Specified by:

getBytes in interface ByteSequence

Parameters:

srcBegin - the byte to start copying from

srcEnd - the byte to end copying at

dst - the destination to copy the bytes to

dstBegin - the byte in the destination to begin the copying

getBytes

public byte[] getBytes()

Description copied from interface: ByteSequence

Returns a byte array containing the bytes in this sequence in the same order as this sequence. The length of the byte array will be the length of this sequence.

Specified by:

getBytes in interface ByteSequence

Returns:

a byte array consisting of exactly this sequence of bytes

setByteAt

public void setByteAt(int index,
                      byte b)

append

public ByteStringBuffer append(byte b)

append

public ByteStringBuffer append(byte[] b)

append

public ByteStringBuffer append(byte[] b,
                               int offset,
                               int length)

ensureCapacity

public void ensureCapacity(int minimumCapacity)

compareTo

public int compareTo(Object otherObject)

Specified by:

compareTo in interface Comparable

compareTo

public int compareTo(ByteStringBuffer otherByteString)

This comparision is byte by byte and one byte string will be "lesser" or "greater" than the other based on the byte values at the first position in which they differ. If both byte strings are identical in all positions but one is longer than the other then longer string is "greater". Only if both byte strings are of the same length and have identical byte values in all positions will they be identical.

Parameters:

otherByteString -

Returns:

0 if the argument byte string is equal to this byte string; a value less than 0 if this byte string is "less" than the argument byte string; and a value greater than 0 if this byte string is "greater" than the argument byte string

equals

public boolean equals(Object otherObject)

Overrides:

equals in class Object
