Class JTypeWildcard

java.lang.Object

com.sun.codemodel.JType

com.sun.codemodel.JClass

com.sun.codemodel.JTypeWildcard

All Implemented Interfaces:

JGenerable, Comparable<JType>

final class JTypeWildcard
extends JClass

Represents a wildcard type like "? extends Foo".

Instances of this class can be obtained from JClass.wildcard() TODO: extend this to cover "? super Integer".

Our modeling of types are starting to look really ugly. ideally it should have been done somewhat like APT, but it's too late now.

Method Details

name

public String name()

Description copied from class: JClass

Gets the name of this class.

Specified by:

name in class JClass

Returns:

name of this class, without any qualification. For example, this method returns "String" for java.lang.String.

fullName

public String fullName()

Description copied from class: JType

Gets the full name of the type. See http://java.sun.com/docs/books/jls/second_edition/html/names.doc.html#25430 for the details.

Specified by:

fullName in class JType

Returns:

Strings like "int", "java.lang.String", "java.io.File[]". Never null.

_package

public JPackage _package()

Description copied from class: JClass

Gets the package to which this class belongs. TODO: shall we move move this down?

Specified by:

_package in class JClass

_extends

public JClass _extends()

Returns the class bound of this variable.

If no bound is given, this method returns Object.

Specified by:

_extends in class JClass

Returns:

Returns the JClass representing the superclass of the entity (class or interface) represented by this JClass. Even if no super class is given explicitly or this JClass is not a class, this method still returns JClass for Object. If this JClass represents Object, return null.

_implements

public Iterator<JClass> _implements()

Returns the interface bounds of this variable.

Specified by:

_implements in class JClass

Returns:

A non-null valid iterator that iterates all JClass objects that represents those interfaces implemented by this object.

isInterface

public boolean isInterface()

Description copied from class: JClass

Checks if this object represents an interface.

Specified by:

isInterface in class JClass

isAbstract

public boolean isAbstract()

Description copied from class: JClass

Checks if this class is an abstract class.

Specified by:

isAbstract in class JClass

substituteParams

protected JClass substituteParams(JTypeVar[] variables,
 List<JClass> bindings)

Description copied from class: JClass

Substitutes the type variables with their actual arguments.

For example, when this class is Map<String,Map<V>>, (where V then doing substituteParams( V, Integer ) returns a JClass for Map<String,Map<Integer>>.

This method needs to work recursively.

Specified by:

substituteParams in class JClass

generate

public void generate(JFormatter f)

Specified by:

generate in interface JGenerable

Overrides:

generate in class JClass
