Method Detail

values

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

Returns:

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

valueOf

public static BuiltInType 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

getName

public java.lang.String getName()

Specified by:

getName in interface Type

getNames

public java.lang.String[] getNames()

fromString

toString

public java.lang.String toString(java.lang.Object value)

justNull

public static <T> java.util.function.Function<org.kie.dmn.api.feel.runtime.events.FEELEvent,T> justNull()

getSymbols

public java.util.Collection<BuiltInTypeSymbol> getSymbols()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Enum<BuiltInType>

determineTypeFromName

public static Type determineTypeFromName(java.lang.String name)

determineTypeFromInstance

public static Type determineTypeFromInstance(java.lang.Object o)

isInstanceOf

public static boolean isInstanceOf(java.lang.Object o,
                                   Type t)

isInstanceOf

public static boolean isInstanceOf(java.lang.Object o,
                                   java.lang.String name)

isInstanceOf

public boolean isInstanceOf(java.lang.Object o)

Description copied from interface: Type

Definition of `instance of` accordingly to FEEL specifications Table 49.

Specified by:

isInstanceOf in interface Type

Returns:

if o is instance of the type represented by this type. If the parameter is null, returns false.

isAssignableValue

public boolean isAssignableValue(java.lang.Object value)

Description copied from interface: Type

Check if the value passed as parameter can be assigned to this type.

Specified by:

isAssignableValue in interface Type

Returns:

if value can be assigned to the type represented by this type. If the parameter is null, returns true.

conformsTo

public boolean conformsTo(Type t)

Description copied from interface: Type

Check if this type does Conform to specified type t accordingly to FEEL DMN specification 10.3.2.9.2 Type Conformance

Specified by:

conformsTo in interface Type

Returns:

if this type does conform to specified type.
