public final class Strings
extends java.lang.Object

Some useful string handling methods, currently mostly here for performance reasons.

Method Summary

Modifier and Type	Method and Description
static java.lang.String	fromAsciiBytes(byte[] bytes, int ofs, int len) Convert a sequence of ASCII bytes into a string.
static int	toAsciiBytes(java.lang.String s, byte[] bytes, int ofs) Brutally convert a string to a sequence of ASCII bytes by discarding all but the lower 7 bits of each char in s.

Method Detail

toAsciiBytes

public static int toAsciiBytes(java.lang.String s,
                               byte[] bytes,
                               int ofs)

Brutally convert a string to a sequence of ASCII bytes by discarding all but the lower 7 bits of each char in s.

The primary purpose of this method is to implement a speedy converter between strings and bytes where characters are known to be limited to the ASCII character set.

Note that the output will consume exactly s.length() bytes.

Parameters:

s - The string to convert.

bytes - The buffer to place the converted bytes into.

ofs - The offset within the buffer to place the converted bytes.

Returns:

The offset within the buffer immediately past the converted string.

fromAsciiBytes

public static java.lang.String fromAsciiBytes(byte[] bytes,
                                              int ofs,
                                              int len)

Convert a sequence of ASCII bytes into a string. Note that no bounds checking is performed on the incoming bytes; the upper bit is silently discarded.

Parameters:

bytes - The buffer to convert to a string.

ofs - The offset within the buffer to start conversion.

len - The number of bytes to convert.

Returns:

A String of length len.
