org.eclipse.datatools.connectivity.oda.spec.result.filter.AtomicExpression
public abstract class AtomicExpression
The abstract base class for all basic, indivisible unit of filter expressions that can be evaluated by itself.
| Method Summary | |
|---|---|
|  ExpressionArguments | getArguments()Returns the expression arguments. | 
|  ExpressionVariable | getVariable()Returns the expression variable. | 
|  boolean | isOptionable()Indicates whether this expression can be optional and skipped in a filter specification if all its expected argument values are null. | 
|  void | setArguments(ExpressionArguments args) | 
|  void | setVariable(ExpressionVariable variable) | 
|  java.lang.String | toString() | 
|  void | validate(ValidationContext context)Validates this expression in the specified context. |
