public class ByteArray

extends java.lang.Object

Wrapper for an array of Bytes. Incorporates offset and length.

Most of the methods in here are final for performance reasons.

Method Detail

length

public final int length()

getByte

public final byte getByte(int index)
                   throws java.lang.IndexOutOfBoundsException

setByte

public final void setByte(int index,
                          byte val)
                   throws java.lang.IndexOutOfBoundsException

getBytes

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

setBytes

public final void setBytes(int dstBegin,
                           byte[] src,
                           int srcBegin,
                           int length)

setBytes

public final void setBytes(int dstBegin,
                           ByteArray src,
                           int srcBegin,
                           int length)

toBytes

public final byte[] toBytes()

Returns a byte array exactly the right size for the valid data in the buf. Note that if this.buf is the right side it is returned directly, otherwise a new array is created of the right size. (Weird.)

Returns:

array of bytes

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
