@UnstableApi
public interface BinaryMemcacheMessage
extends MemcacheMessage

An interface that defines a binary Memcache message, providing common properties for BinaryMemcacheRequest and BinaryMemcacheResponse.

A BinaryMemcacheMessage always consists of a header and optional extras or/and a key.

Method Detail

magic

byte magic()

Returns the magic byte for the message.

Returns:

the magic byte.

setMagic

BinaryMemcacheMessage setMagic(byte magic)

Sets the magic byte.

Parameters:

magic - the magic byte to use.

See Also:

for typesafe opcodes.

opcode

byte opcode()

Returns the opcode for the message.

Returns:

the opcode.

setOpcode

BinaryMemcacheMessage setOpcode(byte code)

Sets the opcode for the message.

Parameters:

code - the opcode to use.

keyLength

short keyLength()

Returns the key length of the message.

This may return 0, since the key is optional.

Returns:

the key length.

extrasLength

byte extrasLength()

Return the extras length of the message.

This may be 0, since the extras content is optional.

Returns:

the extras length.

dataType

byte dataType()

Returns the data type of the message.

Returns:

the data type of the message.

setDataType

BinaryMemcacheMessage setDataType(byte dataType)

Sets the data type of the message.

Parameters:

dataType - the data type of the message.

totalBodyLength

int totalBodyLength()

Returns the total body length.

Note that this may be 0, since the body is optional.

Returns:

the total body length.

setTotalBodyLength

BinaryMemcacheMessage setTotalBodyLength(int totalBodyLength)

Sets the total body length.

Note that this may be 0, since the body length is optional.

Parameters:

totalBodyLength - the total body length.

opaque

int opaque()

Returns the opaque value.

Returns:

the opaque value.

setOpaque

BinaryMemcacheMessage setOpaque(int opaque)

Sets the opaque value.

Parameters:

opaque - the opaque value to use.

cas

long cas()

Returns the CAS identifier.

Returns:

the CAS identifier.

setCas

BinaryMemcacheMessage setCas(long cas)

Sets the CAS identifier.

Parameters:

cas - the CAS identifier to use.

key

ByteBuf key()

Returns the optional key of the document.

Returns:

the key of the document.

setKey

BinaryMemcacheMessage setKey(ByteBuf key)

Sets the key of the document. ReferenceCounted.release() ownership of key is transferred to this BinaryMemcacheMessage.

Parameters:

key - the key of the message. ReferenceCounted.release() ownership is transferred to this BinaryMemcacheMessage.

extras

ByteBuf extras()

Returns a ByteBuf representation of the optional extras.

Returns:

the optional extras.

setExtras

BinaryMemcacheMessage setExtras(ByteBuf extras)

Sets the extras buffer on the message. ReferenceCounted.release() ownership of extras is transferred to this BinaryMemcacheMessage.

Parameters:

extras - the extras buffer of the document. ReferenceCounted.release() ownership is transferred to this BinaryMemcacheMessage.

retain

BinaryMemcacheMessage retain()

Increases the reference count by 1.

Specified by:
