Enum Constant Detail

INOUT

public static final PParameterDirection INOUT

Default value, no additional constraint is applied

IN

public static final PParameterDirection IN

The parameters marked with this constraints shall be set to a value before calling the pattern

OUT

public static final PParameterDirection OUT

The parameters marked with this constraints shall not be set to a value before calling the pattern

Method Detail

values

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

Returns:

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

valueOf

public static PParameterDirection 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
