Enum Constant Detail

ANY

public static final RelOptRuleOperand.Dummy ANY

Signifies that operand can have any number of children.

Method Detail

values

public static final RelOptRuleOperand.Dummy[] values()

Returns an array containing the constants of this enum type, in the order they're declared. This method may be used to iterate over the constants as follows:

for(RelOptRuleOperand.Dummy c : RelOptRuleOperand.Dummy.values())
        System.out.println(c);

Returns:

an array containing the constants of this enum type, in the order they're declared

valueOf

public static RelOptRuleOperand.Dummy valueOf(String name)

Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum type has no constant with the specified name
