Method Detail

values

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

Returns:

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

valueOf

public static InstanceRoleType 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<InstanceRoleType>

fromValue

public static InstanceRoleType fromValue(java.lang.String value)

Use this in place of valueOf.

Parameters:

value - real value

Returns:

InstanceRoleType corresponding to the value
