Method Detail

values

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

Returns:

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

valueOf

public static DataFilterOperator 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

forText

public static DataFilterOperator forText(java.lang.String text)

Returns the DataFilterOperator who's getStringEquivalent() matches the passed text

Parameters:

text - - Text to find matching operator for

Returns:

DataFilterOperator or null

getStringEquivalent

public abstract java.lang.String getStringEquivalent()

Returns a String representation, '=' for EQUAL, '>=' for GREATER_THAN_OR_EQUAL.

Returns:

String equivalent

flip

public abstract DataFilterOperator flip()

Returns the opposite direction operator. Note, not all operators will return different operators. ex, <= flip() becomes > use: x <= 10 can become 10 > x

Returns:

opposite directional operator
