Method Summary

Modifier and Type	Method and Description
static boolean	equalBytes(java.nio.ByteBuffer buffer1, java.nio.ByteBuffer buffer2) Returns true if two byte buffers have equal limits, plus equal bytes in all buffer positions before the limit, regardless of the current position() in either buffer.
static byte[]	getBytes(java.nio.ByteBuffer byteBuffer) Gets the full contents of a byteBuffer (= its bytes from position zero to limit() ) as a byte array.
static byte[]	getRemainingBytes(java.nio.ByteBuffer byteBuffer) Gets the remaining contents of a byteBuffer (= its bytes from its current position to limit() ) as a byte array.
static java.lang.String	toHex(java.nio.ByteBuffer byteBuffer) Builds a hexadecimal representation of the contents of any ByteBuffer

Method Detail

equalBytes

public static boolean equalBytes(java.nio.ByteBuffer buffer1,
                                 java.nio.ByteBuffer buffer2)

Returns true if two byte buffers have equal limits, plus equal bytes in all buffer positions before the limit, regardless of the current position() in either buffer.

Parameters:

buffer1 - The first buffer to be compared

buffer2 - The secondbuffer to be compared

Returns:

true if two byte buffers have equal limits, plus equal bytes in all buffer positions before the limit

toHex

public static java.lang.String toHex(java.nio.ByteBuffer byteBuffer)

Builds a hexadecimal representation of the contents of any ByteBuffer

Parameters:

byteBuffer - The bytebuffer

Returns:

the contents of the bytebuffer represented in hex

getBytes

public static byte[] getBytes(java.nio.ByteBuffer byteBuffer)

Gets the full contents of a byteBuffer (= its bytes from position zero to limit() ) as a byte array. The current position is left intact.

Parameters:

byteBuffer - The byteBuffer whose full contents are to be obtained as a byte array

Returns:

The bytes held in the given byteBuffer from its rewind() position to its limit() position. This is not the same as the (result of) byteBuffer's array() method, if the given byteBuffer was splice() from another byteBuffer at another position than zero, or it its limit() is less than its capacity().

getRemainingBytes

public static byte[] getRemainingBytes(java.nio.ByteBuffer byteBuffer)

Gets the remaining contents of a byteBuffer (= its bytes from its current position to limit() ) as a byte array. The current position is left intact.

Parameters:

byteBuffer - The byteBuffer whose remaining contents are to be obtained as a byte array

Returns:

The bytes held in the given byteBuffer from its current position to its limit() position. This is not the same as the (result of) byteBuffer's array() method, if the given byteBuffer was splice() from another byteBuffer at another position than zero, or it its limit() is less than its capacity().
