Method Detail

values

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

Returns:

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

valueOf

public static TaskScope 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

fromId

public static TaskScope fromId(byte id)

Convert from an ID returned by getId() back to the TaskScope instance

Parameters:

id - of a TaskScope

Returns:

Instance of TaskScope id references

Throws:

java.lang.IllegalArgumentException - If id is not a valid ID

fromName

public static TaskScope fromName(java.lang.String name)

Convert the name of a scope to a TaskScope instance in a case insensitive way. If name is null return the default scope, DATABASE

Parameters:

name - of scope or null

Returns:

Instance of TaskScope

Throws:

java.lang.IllegalArgumentException - If name is not a valid scope

translateIdToName

public static java.lang.String translateIdToName(byte id)

Convert a scope ID to the name of that scope

Parameters:

id - of a TaskScope

Returns:

Name of scope id references

Throws:

java.lang.IllegalArgumentException - If id is not a valid ID

getId

public byte getId()

Returns:

The ID of this scope
