Method Detail

path

String path()

Returns the path inside a JSON document where values will be obtained/mutated. Some sub-document operations authorize the use of an empty path while other don’t.

Returns:

the path to work from inside the JSON document.

pathLength

int pathLength()

Returns:

the length of the path as encoded in the content() (can serve as an offset from 0 to find the path in the content).

opcode

byte opcode()

Returns:

the opcode of the operation

See Also:

KeyValueHandler.OP_SUB_GET and other OP_SUB_ constants for the list of opcodes

content

ByteBuf content()

The ByteBuf bearing the full content for this request. The content is at a minimum comprised of the path() as UTF8 bytes, and can also have any other relevant payload appended (eg. a JSON fragment for mutative operations, see BinarySubdocMutationRequest.fragment()).

This buffer is to be automatically released once the message has been written on the wire.

Returns:

the ByteBuf to serve as a memcached protocol message body.
