Class ByteArrayCharSequence

java.lang.Object

it.unimi.di.law.bubing.util.ByteArrayCharSequence

All Implemented Interfaces:

java.lang.CharSequence

public class ByteArrayCharSequence
extends java.lang.Object
implements java.lang.CharSequence

An adapter exposing a byte array as an ISO-8859-1-encoded character sequence.

An instance of this adapter can be reused by wrapping a new byte array.

Note that for convenience this class exposes a hashCode() method that return the same result as String, but equality is not by content.

Constructor Detail

ByteArrayCharSequence

public ByteArrayCharSequence(byte[] b,
                             int offset,
                             int length)

Creates a new byte-array character sequence using the provided byte-array fragment.

Parameters:

b - a byte array.

offset - the first valid byte in b.

length - the number of valid bytes in b, starting at offset.

ByteArrayCharSequence

public ByteArrayCharSequence(byte[] b)

Creates a new byte-array character sequence using the provided byte array.

Parameters:

b - a byte array.

ByteArrayCharSequence

public ByteArrayCharSequence()

Creates a new empty byte-array character sequence.

Method Detail

wrap
