Field Details

ID

public static final int ID
The context code sets id.
Field Value:
1

STANDARD

public static final CodeSetServiceContext STANDARD
The standard component to include in the messages.

char_data

public int char_data
The encoding, used to transfer the narrow (1 byte) character data. The default value is taken from CharSets_OSF.NATIVE_CHARACTER.

wide_char_data

public int wide_char_data
The encoding, used to transfer the wide character data. The default value is taken from CharSets_OSF.NATIVE_WIDE_CHARACTER.

Method Details

find

public static CodeSetServiceContext find(ServiceContext[] contexts)
Find and return the code set service context in the give contexts array. Returns STANDARD if no code set context is present.
Parameters:
contexts - the array of contexts, can be null.

negotiate

public static CodeSetServiceContext negotiate(IOR.CodeSets_profile profile)
Select the suitable encoding that is defined in the provided profile. TODO character encoding. Now the encoding can be set, but it is ignored. If you take this task, scan 'TODO character encoding' for relevant places.

negotiate

protected static int negotiate(IOR.CodeSets_profile.CodeSet_component profile,
                               int our_native,
                               int final_decission)
Negotiate about the character encoding. Prefer our native encoding, if no, prefer IORs native encoding, if no, find any encoding, supported by both sides, if no, return the specified final decission.
Parameters:
profile - the component profile in IOR.
our_native - our native encoding
final_decission - the encoding that must be returned if no compromise is found.
Returns:
the resulted encoding.

readContext

public void readContext(AbstractCdrInput input)
Read the context from the given stream. Does not read the code sets id.

toString

public String toString()
Return a string representation.
Overrides:
toString in interface ServiceContext

write

public void write(AbstractCdrOutput output)
Write the context to the given stream, including the code sets id.
Overrides:
write in interface ServiceContext
