Enum Constant Detail

LOOSE

public static final TypeMatchingStrategy LOOSE

Matches type or any subtype. Matches types with different nullability/voidability. Allows loose matches.

STRICT_NULLABILITY

public static final TypeMatchingStrategy STRICT_NULLABILITY

Matches type or any subtype. Does not match types with different nullability/voidability. Allows loose matches.

SUBTYPES

public static final TypeMatchingStrategy SUBTYPES

Matches type or any subtype. Does not match types with different nullability/voidability. Does not allow loose matches.

EXACT

public static final TypeMatchingStrategy EXACT

Does not match subtypes. Does not match types with different nullability/voidability. Does not allow loose matches.

Method Detail

values

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

Returns:

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

valueOf

public static TypeMatchingStrategy 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

match

public TypeMatchingStrategy.MatchResult match(JSType templateType,
                                              JSType type)
