Method Summary
Modifier and TypeMethodDescriptionint
getMapSize
(MessageAnnotations value) Gets the number of elements that will result when this type is encoded into an AMQP Map type.boolean
hasMap
(MessageAnnotations value) Returns false when the value to be encoded has no Map body and can be written as a Null body type instead of a Map type.void
writeMapEntries
(ProtonBuffer buffer, Encoder encoder, EncoderState state, MessageAnnotations annotations) Performs the write of the Map entries to the given buffer, the caller takes care of writing the Map preamble and tracking the final size of the written elements of the Map.Methods inherited from class org.apache.qpid.protonj2.codec.encoders.AbstractDescribedMapTypeEncoder

hasMap
Description copied from class:AbstractDescribedMapTypeEncoder
Returns false when the value to be encoded has no Map body and can be written as a Null body type instead of a Map type.- Specified by:
hasMap
in classAbstractDescribedMapTypeEncoder<Symbol,
Object, MessageAnnotations> - Parameters:
value
- the value which be encoded as a map type.- Returns:
- true if the type to be encoded has a Map body, false otherwise.
-
getMapSize
Description copied from class:AbstractDescribedMapTypeEncoder
Gets the number of elements that will result when this type is encoded into an AMQP Map type.- Specified by:
getMapSize
in classAbstractDescribedMapTypeEncoder<Symbol,
Object, MessageAnnotations> - Parameters:
value
- the value which will be encoded as a map type.- Returns:
- the number of elements that should comprise the encoded list.
-
writeMapEntries
public void writeMapEntries(ProtonBuffer buffer, Encoder encoder, EncoderState state, MessageAnnotations annotations) Description copied from class:AbstractDescribedMapTypeEncoder
