TypeDetailsHelper

public TypeDetailsHelper()

Method Details

resolveSuperType

public static TypeDetails resolveSuperType(TypeDetails type,
 Class<?> superType)

Resolve type to the corresponding occurrence of superType in its type hierarchy, substituting type variables at each hierarchy edge.

Returns:

the resolved super type, or null if type does not implement it

extractElementType

public static TypeDetails extractElementType(TypeDetails type)

Extract the collection element or map value type.

extractCollectionElementType

public static TypeDetails extractCollectionElementType(TypeDetails type)

extractMapKeyType

public static TypeDetails extractMapKeyType(TypeDetails type)

extractMapValueType

public static TypeDetails extractMapValueType(TypeDetails type)

resolveRelativeType

public static TypeDetails resolveRelativeType(TypeDetails type,
 TypeVariableScope container)

Given an attribute member type and a concrete container type, resolve the type of the attribute relative to that container.

For example, consider

class Item<T> {
    T id;
}
class Hat extends Item<Integer> {
    ...
}

Given this model, a call to resolve the type of id relative to Hat will return ClassTypeDetails(Integer). A call to resolve the type of id relative to Item returns ParameterizedTypeDetails(T) (roughly Object)

findTypeVariableDetails

public static TypeVariableDetails findTypeVariableDetails(String identifier,
 List<TypeVariableDetails> typeParameters)

resolveRelativeClassType

public static ClassBasedTypeDetails resolveRelativeClassType(TypeDetails memberType,
 TypeVariableScope containerType)

Very much the same as resolveRelativeType(TypeDetails, TypeVariableScope), except that here we resolve the relative type to the corresponding ClassBasedTypeDetails which gives easy access to the type's ClassDetails

resolveRawClass

public static ClassDetails resolveRawClass(TypeDetails typeDetails)

Given a type, resolve the underlying ClassDetails

See Also:

• TypeDetails.determineRawClass()

resolveTypeVariableFromParameterizedType

public static TypeDetails resolveTypeVariableFromParameterizedType(ParameterizedTypeDetails parameterizedType,
 TypeVariableDetails typeVariable)

Resolve a type variable's type relative to the provided parameterized type.

Parameters:

parameterizedType - the parameterized type used to resolve the type variable's relative type

typeVariable - the type variable to resolve

Returns:

the type variable's relative type

arrayOf

public static ArrayTypeDetails arrayOf(TypeDetails constituentType,
 ModelsContext modelsContext)

Make an array type of the given component type
