Constructor Detail

SASListDelegate

public SASListDelegate()

Method Detail

remoteObject

public java.lang.Object remoteObject()

_setRemoteHandle

public void _setRemoteHandle(java.lang.Object o)

Description copied from interface: LocalModelInterface

Sets the proxy handle

Specified by:

_setRemoteHandle in interface com.sas.rmi.LocalModelInterface

firePropertyChange

public void firePropertyChange(java.lang.String prop,
                               java.lang.Object oldv,
                               java.lang.Object newv)

Description copied from interface: ComponentInterface

Report a bound property update to any registered listeners. This method returns immediately without any action if there are no registered PropertyChangeEvent listeners. No event is fired if old and new are equal and non-null. This method corresponds to the java.beans.PropertyChangeSupport firePropertyChange method, which we cannot call directly since we have our own com.sas.beans.PropertyChangeEvent.

Specified by:

firePropertyChange in interface com.sas.ComponentInterface

Overrides:

firePropertyChange in class com.sas.Component

Parameters:

prop - The name of the property that was changed. null may be passed in to indicate that a generic change to the component (and not a specific property) was made.

oldv - The old value of the property. null may be passed in to indicate that the old value is unknown.

newv - The new value of the property. null may be passed in to indicate that the new value is unknown.

See Also:

ComponentInterface.firePropertyChange(java.lang.String, java.lang.Object, java.lang.Object)

parseList

protected void parseList(com.sas.collection.hlist.HListInterface membersList,
                         com.sas.collection.OrderedCollectionInterface parsedList)

Parse the hlist returned from the _getMembers call into a string ordered collection based on what has been specified to be displayed. This default implementation will assume the hlist has Strings already parsed for all items. Subclasses with sublists should override this method without calling super.

Parameters:

membersList - The filled in hlist returned from the _getMembers call

parsedList - The collection that will be emptied and filled with the parsed strings

resubmitQuery

protected void resubmitQuery()

Execute the query to get the names of SAS remote members with the current query information, if the needs_refresh flag is on

contains

public boolean contains(java.lang.Object element)

clone

public java.lang.Object clone()
                       throws java.lang.CloneNotSupportedException

Description copied from class: Component

Return a clone of the object.

Overrides:

clone in class com.sas.Component

Returns:

a clone of the object.

Throws:

java.lang.CloneNotSupportedException - if the model attached to the component being cloned will not allow the clone to attach.

StaticOrderedCollectionInterface.clone()

equals

public boolean equals(com.sas.collection.StaticOrderedCollectionInterface orderedCollection)

See Also:

StaticOrderedCollectionInterface.equals(com.sas.collection.StaticOrderedCollectionInterface)

toString

public java.lang.String toString()

Returns the collection of items in a String by calling toString on the ordered collection of items

Overrides:

Returns:

A string consisting of the comma separated items

contentsChanged

public void contentsChanged(com.sas.collection.ContentsChangedEvent cce)

removeContentsChangedListener

public void removeContentsChangedListener(com.sas.collection.ContentsChangedListener listener)

See Also:

ContentsChangedSource.removeContentsChangedListener(com.sas.collection.ContentsChangedListener)

fireContentsChanged

protected void fireContentsChanged(com.sas.collection.ContentsChangedEvent event)

Send a ContentsChangedEvent to all the ContentsChangedListener objects in the listener list. The listener list is copied first, so the event is sent only to each item which is in the list at the time of this copy, even if adds or removes are performed after the send has started. Also sends the ContentsChangedEvent, which extends PropertyChangeEvent, to all registered propertyChangeListeners, if there are any.

Parameters:

the - event to send

See Also:

addContentsChangedListener(com.sas.collection.ContentsChangedListener), removeContentsChangedListener(com.sas.collection.ContentsChangedListener)

fireContentsChanged

protected void fireContentsChanged()

Fire a default contents changed event. A ContentsChangedEvent will be constructed with this as the source and fireContentsChanged will be called.
