public abstract class AbstractArrayTypeDecoder extends AbstractPrimitiveTypeDecoder<Object> implements PrimitiveArrayTypeDecoder
Base for the decoders of AMQP Array types that defaults to returning opaque Object values to match what the other decoders do. External decoding tools will need to use theTypeDecoder.isArrayType()
checks to determine how they want to read and return array types.

Method Detail
-
getTypeClass
public Class<Object> getTypeClass()
- Specified by:
getTypeClass
in interfaceStreamTypeDecoder<Object>
- Specified by:
getTypeClass
in interfaceTypeDecoder<Object>
- Returns:
- the Class that this decoder handles.
-
isArrayType
public boolean isArrayType()
- Specified by:
isArrayType
in interfaceStreamTypeDecoder<Object>
- Specified by:
isArrayType
in interfaceTypeDecoder<Object>
- Overrides:
isArrayType
in classAbstractPrimitiveTypeDecoder<Object>
- Returns:
- true if the underlying type that is going to be decoded is an array type
-
readValue
public Object readValue(ProtonBuffer buffer, DecoderState state) throws DecodeException
Description copied from interface:TypeDecoder
Reads the next type from the given buffer and returns it.- Specified by:
readValue
in interfaceTypeDecoder<Object>
- Parameters:
buffer
- the source of encoded data.state
- the current state of the decoder.- Returns:
- the next instance in the stream that this decoder handles.
- Throws:
DecodeException
- if an error is encountered while reading the next value.
-
readValue
public Object readValue(InputStream stream, StreamDecoderState state) throws DecodeException
Description copied from interface:StreamTypeDecoder
Reads the next type from the given buffer and returns it.- Specified by:
readValue
in interfaceStreamTypeDecoder<Object>
- Parameters:
stream
- the source of encoded data.state
- the current state of the decoder.- Returns:
- the next instance in the stream that this decoder handles.
- Throws:
DecodeException
- if an error is encountered while reading the next value.
-
skipValue
public void skipValue(ProtonBuffer buffer, DecoderState state) throws DecodeException
Description copied from interface:TypeDecoder
Skips over the bytes that compose the type this descriptor decodes.Skipping values can be used when the type is not used or processed by the application doing the decoding. An example might be an AMQP message decoder that only needs to decode certain parts of the message and not others.
- Specified by:
skipValue
in interfaceTypeDecoder<Object>
- Parameters:
buffer
- The buffer that contains the encoded type.state
- The decoder state.- Throws:
DecodeException
- if an error occurs while skipping the value.
-
skipValue
public void skipValue(InputStream stream, StreamDecoderState state) throws DecodeException
Description copied from interface:StreamTypeDecoder
Skips over the bytes that compose the type this descriptor decodes.Skipping values can be used when the type is not used or processed by the application doing the decoding. An example might be an AMQP message decoder that only needs to decode certain parts of the message and not others.
- Specified by:
skipValue
in interfaceStreamTypeDecoder<Object>
- Parameters:
stream
- The stream that contains the encoded type.state
- The decoder state.- Throws:
DecodeException
- if an error occurs while skipping the value.
