Constructor Detail

REDBlockIterator

public REDBlockIterator(byte[] buffer,
                        int offset,
                        int length)

Ctor.

Parameters:

buffer - the byte buffer that contains the RED payload.

offset - the offset in the buffer where the RED payload begins.

length - the length of the RED payload.

Method Detail

matchFirst

public static REDBlock matchFirst(Predicate<REDBlock> predicate,
                                  byte[] buffer,
                                  int offset,
                                  int length)

Matches a RED block in the RED payload.

Parameters:

predicate - the predicate that is used to match the RED block.

buffer - the byte buffer that contains the RED payload.

offset - the offset in the buffer where the RED payload begins.

length - the length of the RED payload.

Returns:

the first RED block that matches the given predicate, null otherwise.

getPrimaryBlock

public static REDBlock getPrimaryBlock(byte[] buffer,
                                       int offset,
                                       int length)

Gets the first RED block in the RED payload.

Parameters:

buffer - the byte buffer that contains the RED payload.

offset - the offset in the buffer where the RED payload begins.

length - the length of the RED payload.

Returns:

the primary RED block if it exists, null otherwise.

isMultiBlock

public static boolean isMultiBlock(byte[] buffer,
                                   int offset,
                                   int length)

Returns true if a specific RED packet contains multiple blocks; false, otherwise.

Parameters:

buffer - the byte buffer that contains the RED payload.

offset - the offset in the buffer where the RED payload begins.

length - the length of the RED payload.

Returns:

true if pkt contains multiple RED blocks; otherwise, false
