Method Detail

values

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

Returns:

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

valueOf

public static ComparisonOperator 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

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<ComparisonOperator>

getXml

public java.lang.String getXml()

Gets the XML short representation for this operator.

Returns:

The XML short representation for this operator.

toComparisonOperator

public static ComparisonOperator toComparisonOperator(java.lang.String xml)

Gets the comparison comparator for the designated XML short representation or null if the XML short representation is not recognised.

Parameters:

xml - The XML short representation for which to find the comparison comparator.

Returns:

The comparison operator for the designated XML short representation code or null.
