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

bound

public JTypeVar bound(JClass c)

Adds a bound to this variable.

Returns:

this

bound

public JClass bound()

Returns:

bound of this variable

_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 . Even if no super class is given explicitly or this is not a class, this method still returns 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 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

declare

public void declare(JFormatter f)

Prints out the declaration of the variable.

Specified by:

declare in interface JDeclaration

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 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
