All Implemented Interfaces:

ComparisonOperator, Serializable, Comparable<SimpleComparisonOperator>

public enum SimpleComparisonOperator
extends Enum<SimpleComparisonOperator>
implements ComparisonOperator

Method Detail

values

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

Returns:

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

valueOf

public static SimpleComparisonOperator 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

toString

public String toString()

Description copied from interface: ComparisonOperator

Returns the operator symbol that represents the comparison.

Specified by:

toString in interface ComparisonOperator

Overrides:

toString in class Enum<SimpleComparisonOperator>

Returns:

operator symbol

ofSymbol

public static SimpleComparisonOperator ofSymbol(String operatorSymbol)

Get the SimpleComparisonOperator for the provided symbol

Parameters:

operatorSymbol - symbol that represents the operator

Returns:

operator
