Class AbstractCdrOutput

protected AbstractDataOutput b

This instance is used to convert primitive data types into the byte sequences.

protected CodeSetServiceContext codeset

The code set information.

protected Version giop

The GIOP version.

protected ORB orb

The associated orb, if any.

public gnuRuntime runtime

The runtime, associated with this stream. This field is only used when reading and writing value types and filled-in in gnu.CORBA.CDR.Vio.

public AbstractCdrOutput()

Creates the stream, requiring the subsequent call of setOutputStream(OutputStream).

public AbstractCdrOutput(OutputStream writeTo)

Creates the stream.

Parameters:

writeTo - a stream to write CORBA output to.

public String[] _truncatable_ids()

Get the truncatable repository ids.

Specified by:

_truncatable_ids in interface ValueBase

Returns:

the array of repository ids, defining the base types, to that basic types this value base can be truncated.

public abstract void align(int boundary)

Align the curretn position at the given natural boundary.

public void cloneSettings(AbstractCdrOutput stream)

Clone all important settings to another stream.

public AbstractCdrOutput createEncapsulation()

Create the encapsulation stream, associated with the current stream. The encapsulated stream must be closed. When being closed, the encapsulation stream writes its buffer into this stream using the CORBA CDR encapsulation rules. It is not allowed to write to the current stream directly before the encapsulation stream is closed. The encoding (Big/Little Endian) inside the encapsulated sequence is the same as used into the parent stream.

Returns:

the encapsulated stream.

Get the current code set context.

public ORB orb()

Return the associated ORB.

Overrides:

orb in interface OutputStream

Returns:

the associated ORB or null is no such is set.

public void setBigEndian(boolean use_big_endian)

Specify if the stream should use the Big Endian (usual for java) or Little Encoding. The default is Big Endian.

Parameters:

use_big_endian - if true, use Big Endian, if false, use Little Endian.

Set the current code set context.

public abstract void setOffset(int an_offset)

Set the alignment offset, if the index of the first byte in the stream is different from 0.

public void setOrb(ORB an_orb)

Set the orb, associated with this stream.

Parameters:

an_orb -

public void setOutputStream(OutputStream writeTo)

Set the output stream that receives the CORBA output.
