Enum Constant Detail

ABSTRACT

public static final State ABSTRACT

Type cannot be instantiated but can be extended

DEFAULT

public static final State DEFAULT

Type can be instantiated and can be extended

FINAL

public static final State FINAL

Type can be instantiated but can't be extended

Method Detail

values

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

Returns:

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

valueOf

public static State 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

canBeInherited

public boolean canBeInherited()

Check if type can be inherited

Returns:

true if can be inherited, otherwise false

canBeInstantiated

public boolean canBeInstantiated()

Check if type can be instantiated

Returns:

true if can be instantiated, otherwise false

isAbstract

public boolean isAbstract()

Utility method to compare state with ABSTRACT

Returns:

true if the current state represents abstract state

of

public static State of(Class<?> clazz)

Get state based on the given class (abstract/final/default)

Parameters:

clazz - the class to check

Returns:

the state of the given class

of

public static State of(String state)

Get state based on the given string ('class' -> DEFAULT, any other -> ABSTRACT

Parameters:

state - the string representation of state

Returns:

the state
