Method Details

deleteObject

public void deleteObject()

Description copied from interface: ProvidedObject

Signals the provided object to delete itself. After calling this method, isDeleted() will return true and where applicable, ProvidedObjectDeletedExceptions will be thrown.

Specified by:

deleteObject in interface ProvidedObject

getID

public ProvidedObjectID getID()

Description copied from interface: ProvidedObject

Returns the ID of this Provided Object

Specified by:

getID in interface ProvidedObject

Returns:

getObject

public Object getObject()
                 throws ProvidedObjectDeletedException

Description copied from interface: ProvidedObject

Same as calling getObject(true);

Specified by:

getObject in interface ProvidedObject

Returns:

Throws:

ProvidedObjectDeletedException - If the object was removed from memory because there were no useful references to it anymore

getObject

public Object getObject(boolean waitIfFuture)
                 throws ProvidedObjectDeletedException

Description copied from interface: ProvidedObject

Returns the object stored in this provided object. If the object is not an instance of ProMFuture, then the object itself is returned. Otherwise, it depends on the parameter whether the ProMFuture is returned, or the calling thread is blocked until the future finished (or is cancelled)

Specified by:

getObject in interface ProvidedObject

Parameters:

waitIfFuture - if set to false, the returned object might be an instance of ProMFuture. Otherwise not.

Returns:

Throws:

ProvidedObjectDeletedException - If the object was removed from memory because there were no useful references to it anymore

setObject

public void setObject(Object newObject)
               throws ProvidedObjectDeletedException

Description copied from interface: ProvidedObject

Changes the content of this provided object by replacing the original object with the new object. This can only be done if the current object has not been deleted yet.

Specified by:

setObject in interface ProvidedObject

Throws:

ProvidedObjectDeletedException - If the object was removed from memory because there were no useful references to it anymore

toString

public String toString()

Overrides:

toString in class Object

getLabel

public String getLabel()

Description copied from interface: ProvidedObject

Returns the label of this provided object

Specified by:

getLabel in interface ProvidedObject

Returns:

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object o)

Overrides:

equals in class Object

nameChanged

public void nameChanged(String newName)

Specified by:

nameChanged in interface NameChangeListener

setLabel

public void setLabel(String label)
              throws ProvidedObjectDeletedException

Description copied from interface: ProvidedObject

Sets the label of this provided object to the new label.

Specified by:

Parameters:

label - the new label of the object

Throws:

ProvidedObjectDeletedException - If the object was removed from memory because there were no useful references to it anymore

pluginCancelled

public void pluginCancelled(PluginContext context)

isDeleted

public boolean isDeleted()

Description copied from interface: ProvidedObject

Returns whether or not this object has been deleted. Note that if this method returns false, no ProvidedObjectDeletedExceptions are thrown in subsequent, synchronized calls to this provided object.

Specified by:

Returns:

getType

public Class<? extends Object> getType()
                                throws ProvidedObjectDeletedException

Description copied from interface: ProvidedObject

Specified by:

getType in interface ProvidedObject

Returns:

Throws:

ProvidedObjectDeletedException - If the object was removed from memory because there were no useful references to it anymore
