All Implemented Interfaces:

IBinaryExpression, IConditionalExpression, IOverridableOperation, IExpression, IHasType, IParsedElement

Direct Known Subclasses:

ConditionalAndExpression, ConditionalOrExpression, EqualityExpression, IdentityExpression, RelationalExpression

public abstract class ConditionalExpression
extends BinaryExpression
implements IConditionalExpression

The base class for conditional expressions with logical operators e.g., && || ==. Models conditional expressions by encapsulating the left and right hand side operands.
