Method Detail

values

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

Returns:

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

valueOf

public static JavaType 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

isAssignableFrom

public boolean isAssignableFrom(TypeDescription typeDescription)

Checks if a type is assignable from this type.

Parameters:

typeDescription - The type that is to be checked.

Returns:

true if this type is assignable from the provided type.

isAssignableTo

public boolean isAssignableTo(TypeDescription typeDescription)

Checks if a type is assignable to this type.

Parameters:

typeDescription - The type that is to be checked.

Returns:

true if this type is assignable to the provided type.

isSubTypeOf

protected abstract boolean isSubTypeOf(TypeDescription typeDescription)

Checks if a given type is a subtype of the given type.

Parameters:

typeDescription - The type that is to be checked.

Returns:

true if this type is a subtype of the provided type.

representedBy

public boolean representedBy(TypeDescription typeDescription)

Checks if this type represents the provided type.

Parameters:

typeDescription - The type that is to be checked.

Returns:

true if this type represents the provided type.

load

public Class<?> load()

Loads the provided type if this is possible or throws an exception if not.

Returns:

The loaded type.
