Class JType

java.lang.Object  extended by com.sun.codemodel.JType
All Implemented Interfaces:
JGenerable, Comparable<JType>
Direct Known Subclasses:
JClass, JPrimitiveType

public abstract class JType
extends Object
implements JGenerable, Comparable<JType>

A representation of a type in codeModel. A type is always either primitive (JPrimitiveType) or a reference type (JClass).

Method Detail

parse

public static JPrimitiveType parse(JCodeModel codeModel,                                   String typeName)
Obtains a reference to the primitive type object from a type name.


owner

public abstract JCodeModel owner()
Gets the owner code model object.


fullName

public abstract String fullName()
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.

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

binaryName

public String binaryName()
Gets the binary name of the type. See http://java.sun.com/docs/books/jls/third_edition/html/binaryComp.html#44909

Returns:
Name like "Foo$Bar", "int", "java.lang.String", "java.io.File[]". Never null.

name

public abstract String name()
Gets the name of this type.

Returns:
Names like "int", "void", "BigInteger".

array

public abstract JClass array()
Create an array type of this type. This method is undefined for primitive void type, which doesn't have any corresponding array representation.

Returns:
A JClass representing the array type whose element type is this type

isArray

public boolean isArray()
Tell whether or not this is an array type.


isPrimitive

public boolean isPrimitive()
Tell whether or not this is a built-in primitive type, such as int or void.


boxify

public abstract JClass boxify()
If this class is a primitive type, return the boxed class. Otherwise return this.

For example, for "int", this method returns "java.lang.Integer".


unboxify

public abstract JType unboxify()
If this class is a wrapper type for a primitive, return the primitive type. Otherwise return this.

For example, for "java.lang.Integer", this method returns "int".


erasure

public JType erasure()
Returns the erasure of this type.


isReference

public final boolean isReference()
Returns true if this is a referenced type.


elementType

public JType elementType()
If this is an array, returns the component type of the array. (T of T[])


toString

public String toString()
Overrides:
toString in class Object

compareTo

public int compareTo(JType o)
Compare two JTypes by FQCN, giving sorting precedence to types that belong to packages java and javax over all others. This method is used to sort generated import statments in a conventional way for readability.

Specified by:
compareTo in interface Comparable<JType>
