Method Detail

values

public static final CompareOperator[] 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(CompareOperator c : CompareOperator.values())
        System.out.println(c);

Returns:

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

valueOf

public static CompareOperator 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

inverse

public CompareOperator inverse()

Returns the inverse comparison operator.

Returns:

Inverse comparison operator.

toString

public String toString()

Returns a string representation of the comparison operator in SQL syntax.

Overrides:

toString in class Enum<CompareOperator>

Returns:

String representation of the comparison operator in SQL syntax.
