ConditionalExpression

public ConditionalExpression(Expression condition,
                     Expression true_expr,
                     Expression false_expr)

Constructs a conditional expression with the specified condition, true part, and false part.

Parameters:

condition - the condition expression.

true_expr - the expression being evaluated if condition is true.

false_expr - the expression being evaluated if condition is false.

Throws:

java.lang.IllegalArgumentException - if one of the parameters is invalid.

NotAnOrphanException - if one of the parameters has a parent object.

Method Detail
