Methods

Modifier and Type	Method and Description
ResolvedType	actualType()
void	actualType(ResolvedType t)
StringBuilder	appendBriefDescription(StringBuilder sb)
StringBuilder	appendErasedSignature(StringBuilder sb)
StringBuilder	appendFullDescription(StringBuilder sb)
StringBuilder	appendSignature(StringBuilder sb)
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.
boolean	equals(Object o)
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.
List<ResolvedType>	getImplementedInterfaces() Returns ordered list of interfaces (in declaration order) that this type implements.
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.
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>).
boolean	isAbstract()
boolean	isArray() Method that indicates whether this type is an array type.
boolean	isInterface()
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.

Method Detail

canCreateSubtypes

public boolean canCreateSubtypes()

Description copied from class: ResolvedType

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.

Specified by:

canCreateSubtypes in class ResolvedType

actualType

public ResolvedType actualType()

actualType

public void actualType(ResolvedType t)

getParentClass

public ResolvedType getParentClass()

Description copied from class: ResolvedType

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.

Specified by:

getParentClass in class ResolvedType

getSelfReferencedType

public ResolvedType getSelfReferencedType()

Description copied from class: ResolvedType

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.

Specified by:

getSelfReferencedType in class ResolvedType

getImplementedInterfaces

public List<ResolvedType> getImplementedInterfaces()

Description copied from class: ResolvedType

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

Specified by:

getImplementedInterfaces in class ResolvedType

Returns:

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

getArrayElementType

public ResolvedType getArrayElementType()

Description copied from class: ResolvedType

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.

Specified by:

getArrayElementType in class ResolvedType

isInterface

public boolean isInterface()

Specified by:

isInterface in class ResolvedType

isAbstract

public boolean isAbstract()

Specified by:

isAbstract in class ResolvedType

isArray

public boolean isArray()

Description copied from class: ResolvedType

Method that indicates whether this type is an array type.

Specified by:

isArray in class ResolvedType

isPrimitive

public boolean isPrimitive()

Description copied from class: ResolvedType

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.

Specified by:

isPrimitive in class ResolvedType

appendSignature

public StringBuilder appendSignature(StringBuilder sb)

Specified by:

appendSignature in class ResolvedType

appendErasedSignature

public StringBuilder appendErasedSignature(StringBuilder sb)

Specified by:

appendErasedSignature in class ResolvedType

appendBriefDescription

public StringBuilder appendBriefDescription(StringBuilder sb)

Specified by:

appendBriefDescription in class ResolvedType

appendFullDescription

public StringBuilder appendFullDescription(StringBuilder sb)

Specified by:

appendFullDescription in class ResolvedType

equals

public boolean equals(Object o)

Overrides:
