Interface CodecOperations

All Known Subinterfaces:: Codec

public interface CodecOperations

The formats of IOR components and service context data used by ORB services are often defined as CDR encapsulations encoding instances of IDL defined data types. The Codec provides a mechanism to transfer these components between their IDL data types and their CDR encapsulation representations.

A Codec is obtained from the CodecFactory. The CodecFactory is obtained through a call to ORB.resolve_initial_references( "CodecFactory" ).

Methods

encode

byte[] encode(Any data)
       throws InvalidTypeForEncoding

Converts the given any into a byte array based on the encoding format effective for this Codec.

Parameters:: data - The data, in the form of an any, to be encoded into a byte array.
Returns:: A byte array containing the encoded Any. This byte array contains both the TypeCode and the data of the type.
Throws:: InvalidTypeForEncoding - thrown if the type is not valid for the encoding format effective for this Codec.

decode

Any decode(byte[] data)
    throws FormatMismatch

Decodes the given byte array into an Any based on the encoding format effective for this Codec.

Parameters:: data - The data, in the form of a byte array, to be decoded into an Any.
Returns:: An Any containing the data from the decoded byte array.
Throws:: FormatMismatch - is thrown if the byte array cannot be decoded into an Any.

encode_value

byte[] encode_value(Any data)
             throws InvalidTypeForEncoding

Converts the given any into a byte array based on the encoding format effective for this Codec. Only the data from the Any is encoded, not the TypeCode.

Parameters:: data - The data, in the form of an Any, to be encoded into a byte array.
Returns:: A byte array containing the data from the encoded any.
Throws:: InvalidTypeForEncoding - thrown if the type is not valid for the encoding format effective for this Codec.

decode_value

Any decode_value(byte[] data,
                 TypeCode tc)
          throws FormatMismatch,
                 TypeMismatch

Decodes the given byte array into an Any based on the given TypeCode and the encoding format effective for this Codec.

Parameters:: data - The data, in the form of a byte array, to be decoded into an Any.; tc - The TypeCode to be used to decode the data.
Returns:: An Any containing the data from the decoded byte array.
Throws:: FormatMismatch - thrown if the byte array cannot be decoded into an Any.; TypeMismatch
