Method Detail

readValue

public java.lang.Long 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 interface TypeDecoder<java.lang.Long>

Overrides:

readValue in class LongTypeDecoder

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 java.lang.Long readValue(java.io.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 interface StreamTypeDecoder<java.lang.Long>

Overrides:

readValue in class LongTypeDecoder

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.

readPrimitiveValue

public long readPrimitiveValue(ProtonBuffer buffer,
                               DecoderState state)
                        throws DecodeException

Description copied from class: LongTypeDecoder

Reads the primitive value from the given ProtonBuffer and returns it.

Overrides:

readPrimitiveValue in class LongTypeDecoder

Parameters:

buffer - The ProtonBuffer where the primitive value should be read from.

state - The DecoderState that can be used during decode of the value.

Returns:

the decoded primitive value.

Throws:

DecodeException - if an error occurs while reading the encoded value.

readPrimitiveValue

public long readPrimitiveValue(java.io.InputStream stream,
                               StreamDecoderState state)
                        throws DecodeException

Description copied from class: LongTypeDecoder

Reads the primitive value from the given InputStream and returns it.

Overrides:

readPrimitiveValue in class LongTypeDecoder

Parameters:

stream - The InputStream where the primitive value should be read from.

state - The DecoderState that can be used during decode of the value.

Returns:

the decoded primitive value.

Throws:

DecodeException - if an error occurs while reading the encoded value.

getTypeCode

public int getTypeCode()

Specified by:

getTypeCode in interface PrimitiveTypeDecoder<java.lang.Long>

Overrides:

getTypeCode in class LongTypeDecoder

Returns:

the AMQP Encoding Code that this primitive type decoder can read.

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 interface TypeDecoder<java.lang.Long>

Overrides:

skipValue in class LongTypeDecoder

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(java.io.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 interface StreamTypeDecoder<java.lang.Long>

Overrides:

skipValue in class LongTypeDecoder

Parameters:

stream - The stream that contains the encoded type.

state - The decoder state.

Throws:

DecodeException - if an error occurs while skipping the value.
