• ### DENORMALIZATION

public static final ContextualParameters.MatrixRole DENORMALIZATION

• ### values

public static  values()
Returns an array containing the constants of this enum type, in the order they are declared.
Returns:
an array containing the constants of this enum type, in the order they are declared
• ### valueOf

public static ContextualParameters.MatrixRole 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
