Map8TypeDecoder

public Map8TypeDecoder()

Method Detail

getTypeCode

public int getTypeCode()

Returns:

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

readSize

public int readSize(ProtonBuffer buffer)
             throws DecodeException

Description copied from interface: MapTypeDecoder

Reads the encoded size of the underlying Map type.

Parameters:

buffer - The buffer containing the encoded Map type.

Returns:

the size in bytes of the encoded Map.

Throws:

DecodeException - if an error occurs reading the value

readCount

public int readCount(ProtonBuffer buffer)
              throws DecodeException

Description copied from interface: MapTypeDecoder

Reads the count of entries in the encoded Map.

This value is the total count of all key values pairs, and should always be an even number as Map types cannot be unbalanced.

Parameters:

buffer - The buffer containing the encoded Map type.

Returns:

the number of elements that we encoded from the original Map.

Throws:

DecodeException - if an error occurs reading the value

readSize

public int readSize(java.io.InputStream stream)
             throws DecodeException

Description copied from interface: MapTypeDecoder

Reads the encoded size of the underlying Map type.

Parameters:

stream - The InputStream containing the encoded Map type.

Returns:

the size in bytes of the encoded Map.

Throws:

DecodeException - if an error occurs reading the value

readCount

public int readCount(java.io.InputStream stream)
              throws DecodeException

Description copied from interface: MapTypeDecoder

Reads the count of entries in the encoded Map.

This value is the total count of all key values pairs, and should always be an even number as Map types cannot be unbalanced.

Parameters:

stream - The InputStream containing the encoded Map type.

Returns:

the number of elements that we encoded from the original Map.

Throws:

DecodeException - if an error occurs reading the value
