public DeleteOnNoLinksOrMessagesTypeDecoder()

Method Details

getTypeClass

public Class<DeleteOnNoLinksOrMessages> getTypeClass()

Description copied from interface: TypeDecoder

Returns the Class that this decoder handles.

Returns:

the Class that this decoder handles

getDescriptorCode

public UnsignedLong getDescriptorCode()

Description copied from interface: DescribedTypeDecoder

Returns the AMQP descriptor code for the type this decoder reads.

Returns:

an unsigned long descriptor code value.

getDescriptorSymbol

public Symbol getDescriptorSymbol()

Description copied from interface: DescribedTypeDecoder

Returns the AMQP descriptor symbol for the type this decoder reads.

Returns:

an symbol descriptor code value.

getMinListElements

protected int getMinListElements()

Description copied from class: AbstractDescribedListTypeDecoder

(@return the minimum number of elements that must appear in this list type}

Specified by:

getMinListElements in class AbstractDescribedListTypeDecoder<DeleteOnNoLinksOrMessages>

getMaxListElements

protected int getMaxListElements()

Description copied from class: AbstractDescribedListTypeDecoder

Returns the maximum number of elements that may appear in this list type.

Specified by:

getMaxListElements in class AbstractDescribedListTypeDecoder<DeleteOnNoLinksOrMessages>

Returns:

the maximum number of elements that may appear in this list type

readSingle

protected DeleteOnNoLinksOrMessages readSingle(ProtonBuffer buffer,
 DecoderState state,
 ListTypeDecoder listDecoder)
                                        throws DecodeException

Description copied from class: AbstractDescribedListTypeDecoder

Reads a single instance of the described list type using the provided decoder. The default implementation performs a series of validation checks on the incoming encoded data and then calls the abstract readListType method which can assume the basic contracts of the encoding are correct and simply read the elements into the final described type object.

Overrides:

readSingle in class AbstractDescribedListTypeDecoder<DeleteOnNoLinksOrMessages>

Parameters:

buffer - The source of the encoded bytes to read the value from.

state - The decoder state that was passed at the start of decoding.

listDecoder - The list decoder that indicates the structure of the encoded lists of elements.

Returns:

a single value that is the described type this decoder reads using the given list decoder.

Throws:

DecodeException - if an error occurs while performing the decode.

readSingle

protected DeleteOnNoLinksOrMessages readSingle(InputStream stream,
 StreamDecoderState state,
 ListTypeDecoder listDecoder)

Overrides:

readSingle in class AbstractDescribedListTypeDecoder<DeleteOnNoLinksOrMessages>

Parameters:

stream - The source of the encoded bytes to read the value from.

state - The decoder state that was passed at the start of decoding.

listDecoder - The list decoder that indicates the structure of the encoded lists of elements.

Returns:

a single value that is the described type this decoder reads using the given list decoder.

Throws:

DecodeException - if an error occurs while performing the decode.

readType

protected DeleteOnNoLinksOrMessages readType(int count,
 ProtonBuffer buffer,

state - The decoder state that was passed at the start of decoding.

Returns:

a single value that is the described type this decoder reads using the given list decoder.

Throws:

DecodeException - if an error occurs while performing the decode.
