newParameterizedTypeWithOwner
public static ParameterizedType newParameterizedTypeWithOwner(Type ownerType, Type rawType, Type... typeArguments) Returns a new parameterized type, applyingtypeArguments
torawType
and enclosed byownerType
.- Returns:
- a
serializable
parameterized type.
-
arrayOf
Returns an array type whose elements are all instances ofcomponentType
.- Returns:
- a
serializable
generic array type.
-
subtypeOf
Returns a type that represents an unknown type that extendsbound
. For example, ifbound
isCharSequence.class
, this returns? extends CharSequence
. Ifbound
isObject.class
, this returns?
, which is shorthand for? extends Object
. -
supertypeOf
Returns a type that represents an unknown supertype ofbound
. For example, ifbound
isString.class
, this returns? super String
. -
canonicalize
Returns a type that is functionally equal but not necessarily equal according toObject.equals()
. The returned type isSerializable
. -
getRawType
-
equal
-
equals
Returns true ifa
andb
are equal. -
hashCodeOrZero
-
typeToString
-
getGenericSupertype
Returns the generic supertype forsupertype
. For example, given a classIntegerSet
, the result for when supertype isSet.class
isSet<Integer>
and the result when the supertype isCollection.class
isCollection<Integer>
. -
getSupertype
Returns the generic form ofsupertype
. For example, if this isArrayList<String>
, this returnsIterable<String>
given the inputIterable.class
.- Parameters:
supertype
- a superclass of, or interface implemented by, this.
-
getArrayComponentType
Returns the component type of this array type.- Throws:
ClassCastException
- if this type is not an array.
-
getCollectionElementType
Returns the element type of this collection type.- Throws:
IllegalArgumentException
- if this type is not a collection.
-
getMapKeyAndValueTypes
Returns a two element array containing this map's key and value types in positions 0 and 1 respectively. -
resolve

resolveTypeVariable
-
indexOf
-
declaringClassOf
Returns the declaring class oftypeVariable
, ornull
if it was not declared by a class. -
