Method Details

getUnsignedByte

static short getUnsignedByte(DirectBuffer buffer,
 int index)

Gets an unsigned byte at the specified absolute index in a buffer.

Parameters:

buffer - the source of value.

index - the absolute index in the buffer.

Returns:

unsigned byte value.

hexDump

static String hexDump(DirectBuffer buffer,
 int fromIndex,
 int length)

hexDump

static String hexDump(byte[] array,
 int fromIndex,
 int length)

prettyHexDump

static String prettyHexDump(DirectBuffer buffer,
 int offset,
 int length)

isOutOfBounds

static boolean isOutOfBounds(int index,
 int length,
 int capacity)

Determine if the requested index and length will fit within capacity.

Parameters:

index - The starting index.

length - The length which will be utilized (starting from index).

capacity - The capacity that index + length is allowed to be within.

Returns:

true if the requested index and length will fit within capacity. false if this would result in an index out of bounds exception.

appendPrettyHexDump
