Class CharArray

java.lang.Object
  jlibs.core.lang.CharArray

All Implemented Interfaces:

CharSequence

public class CharArray
extends Object
implements CharSequence

This is CharSequence implementation.

• the char array passed to the constructor is not copied.
• supports to change the char array using set(char[], int, int)
• internal state can be queried using buffer(), offset() and length()

Constructor Summary

CharArray(char[] buff)
Allocates a new CharArray so that it represents the sequence of characters currently contained in the character array argument.

CharArray(char[] buff, int offset, int length)
Allocates a new CharArray that contains characters from a subarray of the character array argument.

Method Summary

CharArrayReader	asReader() creates a new CharArrayReader to read contents of this chararray
char[]	buffer() returns the char buffer used by this instance
char	charAt(int index)
int	length()
int	offset() returns the index of first character in char buffer
void	set(char[] buff, int offset, int length) replaces the internal char buffer with the given char array.

Constructor Detail

CharArray

public CharArray(char[] buff)

Allocates a new CharArray so that it represents the sequence of characters currently contained in the character array argument. The contents of the character array are not copied;

Parameters:

buff - value of the chararray

CharArray

public CharArray(char[] buff,
                 int offset,
                 int length)

Allocates a new CharArray that contains characters from a subarray of the character array argument. The offset argument is the index of the first character 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 characters

offset - The initial offset

length - The length

Throws:

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

Method Detail

set

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

replaces the internal char buffer with the given char array.

Parameters:

buff - Array that is the source of characters

offset - The initial offset

length - The length
