Class ResolvedPrimitiveType

java.lang.Object

com.fasterxml.classmate.ResolvedType

com.fasterxml.classmate.types.ResolvedPrimitiveType

All Implemented Interfaces:

Type

public final class ResolvedPrimitiveType
extends ResolvedType

Type used for Java primitive types (which does not include arrays here).

Since set of primitive types is bounded, constructor is defined as protected, and class final; that is, new primitive types are not to be constructed by calling applications.

Field Summary

Fields

Modifier and Type	Field and Description
protected String	_description Human-readable description should be simple as well
protected String	_signature Primitive types have single-character Signature, easy and efficient to just store here

Method Summary

Modifier and Type	Method and Description
static List<ResolvedPrimitiveType>	all()
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.
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.
String	getErasedSignature() Method that returns type erased signature of the type; suitable as non-generic signature some packages need
String	getFullDescription() Human-readable full description of type, which includes specification of super types (in brief format)
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>).
String	getSignature() Method that returns full generic signature of the type; suitable as signature for things like ASM package.
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.
static ResolvedPrimitiveType	voidType()

Method Detail

all

public static List<ResolvedPrimitiveType> all()

voidType

public static ResolvedPrimitiveType voidType()

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

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

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

isInterface

public boolean isInterface()

Specified by:

isInterface in class ResolvedType

isAbstract

public boolean isAbstract()

Specified by:

isAbstract in class ResolvedType

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

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

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

getSignature

public String getSignature()

Description copied from class: ResolvedType

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

Overrides:

getSignature in class ResolvedType

getErasedSignature

Description copied from class: ResolvedType

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

Overrides:

getErasedSignature in class ResolvedType

getFullDescription

public String getFullDescription()

Description copied from class: ResolvedType

Human-readable full description of type, which includes specification of super types (in brief format)

Overrides:
