getObservedObject()

getObservedAttribute

String getObservedAttribute()

Class is disabled.

Gets the attribute being observed.

Returns:

The attribute being observed.

See Also:

setObservedAttribute(java.lang.String)

setObservedAttribute

void setObservedAttribute(String attribute)

Class is disabled.

Sets the attribute to observe.

Parameters:

attribute - The attribute to observe.
