ResolvedType

protected ResolvedType(Class<?> cls,
            TypeBindings bindings)

Method Detail

canCreateSubtypes

public abstract boolean canCreateSubtypes()

Method that can be used to check if call to TypeResolver.resolveSubtype(ResolvedType, Class) may ever succeed; if false, it will fail with an exception, if true, it may succeed.

canCreateSubtype

public final boolean canCreateSubtype(Class<?> subtype)

Method that can be used to check if call to TypeResolver.resolveSubtype(ResolvedType, Class) will succeed for specific type; if false, it will fail with an exception; if tru it will succeed.

getErasedType

public Class<?> getErasedType()

Returns type-erased Class that this resolved type has.

getParentClass

public abstract ResolvedType getParentClass()

Returns parent class of this type, if it has one; primitive types and interfaces have no parent class, nor does Object type Object. Also, placeholders for cyclic (recursive) types return null for this method.

getSelfReferencedType

public abstract ResolvedType getSelfReferencedType()

Accessor that must be used to find out actual type in case of "self-reference"; case where type refers recursive to itself (like, T implements Comparable<T>). For all other types returns null but for self-references "real" type. Separate accessor is provided to avoid accidental infinite loops.

getArrayElementType

public abstract ResolvedType getArrayElementType()

Method that can be used to access element type of array types; will return null for non-array types, and non-null type for array types.

getImplementedInterfaces

public abstract List<ResolvedType> getImplementedInterfaces()

Returns ordered list of interfaces (in declaration order) that this type implements.

Returns:

List of interfaces this type implements, if any; empty list if none

getTypeParameters

public List<ResolvedType> getTypeParameters()

Returns list of generic type declarations for this type, in order they are declared in class description.

getTypeBindings

public TypeBindings getTypeBindings()

Method for accessing bindings of type variables to resolved types in context of this type. It has same number of entries as return List of getTypeParameters(), accessible using declared name to which they bind; for example, Map has 2 type bindings; one for key type (name "K", from Map.java) and one for value type (name "V", from Map.java).

typeParametersFor

public List<ResolvedType> typeParametersFor(Class<?> erasedSupertype)

Method that will try to find type parameterization this type has for specified super type

Returns:

List of type parameters for specified supertype (which may be empty, if supertype is not a parametric type); null if specified type is not a super type of this type

findSupertype

public ResolvedType findSupertype(Class<?> erasedSupertype)

Method for finding super type of this type that has specified type erased signature. If supertype is an interface which is implemented using multiple inheritance paths, preference is given to interfaces implemented "highest up the stack" (directly implemented interfaces over interfaces superclass implements).

isInterface

public abstract boolean isInterface()

isConcrete

public final boolean isConcrete()

isAbstract

public abstract boolean isAbstract()

isArray

public abstract boolean isArray()

Method that indicates whether this type is an array type.

isPrimitive

public abstract boolean isPrimitive()

Method that indicates whether this type is one of small number of primitive Java types; not including array types of primitive types but just basic primitive types.

isInstanceOf

public final boolean isInstanceOf(Class<?> type)

getConstructors

public List<RawConstructor> getConstructors()

getMemberFields

public List<RawField> getMemberFields()

getMemberMethods

public List<RawMethod> getMemberMethods()

getStaticFields

public List<RawField> getStaticFields()

getStaticMethods

public List<RawMethod> getStaticMethods()

getSignature

public String getSignature()

Method that returns full generic signature of the type; suitable as signature for things like ASM package.

getErasedSignature

public String getErasedSignature()

Method that returns type erased signature of the type; suitable as non-generic signature some packages need

getFullDescription
