Method Detail

values

public static CmpV.OpV[] values()

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

for (CmpV.OpV c : CmpV.OpV.values())
    System.out.println(c);

Returns:

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

valueOf

public static CmpV.OpV valueOf(java.lang.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:

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

java.lang.NullPointerException - if the argument is null

eval

public abstract boolean eval(InputInfo ii,
           Item a,
           Item b)
                      throws QueryException

Evaluates the expression.

Parameters:

ii - input info

a - first item

b - second item

Returns:

result

Throws:

QueryException - query exception

swap

public abstract CmpV.OpV swap()

Swaps the comparator.

Returns:

swapped comparator

invert

public abstract CmpV.OpV invert()

Inverts the comparator.

Returns:

inverted comparator

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<CmpV.OpV>
