public abstract class Condition

extends Expression

An abstract base class for an Expression that represents a condition, which specifies a combination of one or more expressions and logical (Boolean) operators and evaluates to true, false, null, or UNKNOWN. The Condition class has methods that create a subclass that specifies a logical AND, NOT, or OR condition.

Method Summary

Condition	and(Condition rhs) Creates a Condition that represents a logical AND condition.
boolean	isCompositeObject() Indicates whether this Condition contains other SyntaxObject objects.
Condition	not() Creates a Condition that represents a logical NOT condition, which reverses, or negates, the Boolean value of this Condition.
Condition	or(Condition rhs) Creates a Condition that represents a logical OR condition.

Method Detail

and

public final Condition and(Condition rhs)

Creates a Condition that represents a logical AND condition. The Condition returned by this method represents a condition that evaluates to true if both this Condition and the specifed right-hand-side Condition are true, evaluates to false if either condition is false, or evaluates to UNKNOWN otherwise.

Parameters:

rhs - A Condition that is the right-hand-side condition.

Returns:

A Condition that represents a logical AND operation on this Condition and the rhs Condition.

or

public final Condition or(Condition rhs)

Creates a Condition that represents a logical OR condition. The Condition returned by this method represents a condition that evaluates to true if either this Condition or the specifed right-hand-side Condition is true, evaluates to false if both conditions are false, or evaluates to UNKNOWN otherwise.

Parameters:

rhs - A Condition that is the right-hand-side condition.

Returns:

A Condition that represents a logical OR operation on this Condition and the rhs Condition.

not

public final Condition not()

Creates a Condition that represents a logical NOT condition, which reverses, or negates, the Boolean value of this Condition. The Condition returned by this method represents a condition that evaluates to true if this Condition is false, evaluates to false if this Condition is true, or evaluates to UNKNOWN if this Condition is UNKNOWN.

Returns:

A Condition that represents the negation of this Condition.

isCompositeObject

public boolean isCompositeObject()

Indicates whether this Condition contains other SyntaxObject objects.

Returns:

A boolean that is true if Condition contains other SyntaxObject objects or is false otherwise.
