Method Detail

values

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

Returns:

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

valueOf

public static RelationalOperator 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

scanNext

public static RelationalOperator scanNext(String str)

startsWithOperator

public static boolean startsWithOperator(String str)

isOperatorString

public static boolean isOperatorString(String str)

fromString

public static RelationalOperator fromString(String symbol)
                                     throws IllegalArgumentException

Throws:

IllegalArgumentException

getSymbol

public String getSymbol()

toString

public String toString()

Overrides:

toString in class Enum<RelationalOperator>

isTrueFor

public <T extends Comparable<? super T>> boolean isTrueFor(T arg1,
                                                           T arg2)

isTrueFor

public <T> boolean isTrueFor(T arg1,
                             T arg2,
                             Comparator<? super T> comp)

isTrueForCompareValue

public boolean isTrueForCompareValue(int c)
