      extended by de.unihalle.informatik.Alida.annotations.Parameter.Direction
All Implemented Interfaces:
java.io.Serializable, java.lang.Comparable<Parameter.Direction>
Enclosing class:
Parameter

public static enum Parameter.Direction
extends java.lang.Enum<Parameter.Direction>

Enumerates the different directions a parameter may, e.g. into or out of an operator. Used for documentation of the processing history and code genereration. UNKNOWN is used for compatibility. If the direction of a Parameter is UNKOWN, the old way using Type is assumed.


Enum Constant Summary
IN
          input parameter
INOUT
          this parameter is as well input as also output of the operator
OUT
          output parameter
UNKNOWN
          undefine direction, used for compatibility with oder Alida version.
 
Method Summary
static Parameter.Direction valueOf(java.lang.String name)
          Returns the enum constant of this type with the specified name.
static Parameter.Direction[] values()
          Returns an array containing the constants of this enum type, in the order they are declared.

Enum Constant Detail

UNKNOWN

public static final Parameter.Direction UNKNOWN
undefine direction, used for compatibility with oder Alida version.


IN

public static final Parameter.Direction IN
input parameter


OUT

public static final Parameter.Direction OUT
output parameter


INOUT

public static final Parameter.Direction INOUT

Method Detail

values

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

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

valueOf

public static Parameter.Direction 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
