Method Detail

serializeToIOBuffer

public com.neeve.io.IOBuffer serializeToIOBuffer(boolean useNative)

Description copied from interface: MessageView

Serializes the MessageView to an IOBuffer.

Ownership of the returned IOBuffer is given to the caller which should dispose of it when done.

The buffer backing the IOBuffer should be flipped (ready for read) upon return.

Specified by:

serializeToIOBuffer in interface MessageView

Parameters:

useNative - Whether the returned buffer should be native.

Returns:

The MessageView serialized to an IOBuffer.

setTag

public final void setTag(int id,
                         Object tag)

Implementation of MessageView.setTag(int, java.lang.Object)

Specified by:

setTag in interface MessageView

getTag

public final Object getTag(int id)

Implementation of MessageView.getTag(int)

Specified by:

getTag in interface MessageView

Returns:

Returns the requested tag

getVfid

public final short getVfid()

Implementation of MessageView.getVfid()

Specified by:

getVfid in interface MessageView

getType

public final short getType()

Implementation of MessageView.getType()

Specified by:

getType in interface MessageView

getMessageEncodingType

public final int getMessageEncodingType()

Implementation of MessageView.getMessageEncodingType()

Specified by:

getMessageEncodingType in interface MessageView

getMessage

public final Object getMessage()

Implementation of MessageView.getMessage()

Specified by:

getMessage in interface MessageView

acquire

public final void acquire()

Implementation of MessageView.acquire()

Specified by:

acquire in interface MessageView

getOwnershipCount

public final int getOwnershipCount()

Implementation of MessageView.getOwnershipCount()

Specified by:

getOwnershipCount in interface MessageView

dispose

public int dispose()

Default implementation of MessageView.dispose()

This is the default implementation of the dispose method. The implementation just decrements the ownership count. Implementations that implement view object pooling or other such functionality should override this method but invoke this method to decrement the object reference count.

Specified by:

dispose in interface MessageView

referenceTracker

public final UtlReferenceTracker referenceTracker()

Description copied from interface: UtlReferenceTracker.HasReferenceTracker

Get an object's reference tracker.

This method returns an object's reference tracker intended for use for debugging purposes. An object should instantiate a tracker only if UtlReferenceTracker.ENABLED is true or UtlReferenceTracker.enabled(Class) is true for the object type. The flag can be enabled via the properties nv.reftracking.enabled or by the nv.reftracking.types=fullclassname1[|fullclassnameN].

Specified by:

referenceTracker in interface UtlReferenceTracker.HasReferenceTracker

toString

public String toString()

Return a string representation of this object

Overrides:

toString in class Object
