execute
@Nonnull public QualifiedValue execute() throws ExpressionException
Description copied from interface:Expression
Compute and return the value of this expression- Throws:
ExpressionException
-
getOpName
public java.lang.String getOpName()
Description copied from interface:Expression
Return a human-readable name for the operation that this expression performs
-
getType
@Deprecated public java.lang.Class<?> getType()
Deprecated.Typing is no longer enforced on expressions.
-
setType
@Deprecated public void setType(java.lang.Class<?> type)
Deprecated.Typing is no longer enforced on expressions, but we can't remove the setter due to serialization.

shutdown
public void shutdown()
Description copied from interface:Expression
Tells the expression to shutdown any polling operations.- Specified by:
shutdown
in interfaceExpression
- Overrides:
shutdown
in classAbstractExpression
-
startup
public void startup()
Description copied from interface:Expression
Tells the expression to startup any polling operations. Expressions that use this can remember the updateListener from connect() to feed update notification to.- Specified by:
