Enum Constant Detail

GT

public static final ComparePredicate.Operation GT

greater than

row column value > comparison value

GE

public static final ComparePredicate.Operation GE

greater or equal

row column value >= comparison value

LT

public static final ComparePredicate.Operation LT

lower than

row column value < comparison value

LE

public static final ComparePredicate.Operation LE

lower or equal

row column value <= comparison value

Method Detail

values

public static ComparePredicate.Operation[] 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 (ComparePredicate.Operation c : ComparePredicate.Operation.values())
    System.out.println(c);

Returns:

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

valueOf

public static ComparePredicate.Operation 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

NullPointerException - if the argument is null
