WrapperObjectOutputStream (Oracle® Coherence Java API Reference)

java.lang.Object
- java.io.OutputStream
- - com.tangosol.io.WrapperDataOutputStream
  - - com.tangosol.io.WrapperObjectOutputStream

All Implemented Interfaces:

com.oracle.coherence.common.io.OutputStreaming, OutputStreaming, Closeable, DataOutput, Flushable, ObjectOutput, AutoCloseable

Direct Known Subclasses:

ExternalizableHelper.ShieldedObjectOutputStream
```
public class WrapperObjectOutputStream
extends WrapperDataOutputStream
implements ObjectOutput
```
This is an imitation ObjectOutputStream class that provides the ObjectOutput interface by delegating to an object that implements the ObjectOutput interface. Primarily, this is intended as a base class for building specific-purpose ObjectOutput wrappers.

```
public WrapperObjectOutputStream(ObjectOutput out)
```
    Construct a WrapperObjectOutputStream that will output to the specified object implementing the ObjectOutput interface.
    
    Parameters:
    
    out - an object implementing ObjectOutput to write to
- Method Detail
  - getObjectOutput
```
public ObjectOutput getObjectOutput()
```
    Obtain the underlying object providing the ObjectOutput interface that this object is delegating to.
    
    Returns:
    
    the underlying ObjectOutput
  - getBytesWritten
```
public long getBytesWritten()
```
    Return the total number of bytes written to the wrapped DataOutput object.
    This method is unsupported.
    
    Overrides:
    
    getBytesWritten in class WrapperDataOutputStream
    
    Returns:
    
    the total number of bytes written
    
    Throws:
    
    UnsupportedOperationException - always
  - writeObject
```
public void writeObject(Object o)
                 throws IOException
```
    Writes the Object o so that the corresponding ObjectInput.readObject() method can reconstitute an Object from the written data.
    
    Specified by:
    
    writeObject in interface ObjectOutput
    
    Parameters:
    
    o - the Object to write
    
    Throws:
    
    IOException - if an I/O error occurs
