Class JPrimitiveType

java.lang.Object

com.sun.codemodel.JType

com.sun.codemodel.JPrimitiveType

All Implemented Interfaces:

JGenerable, Comparable<JType>

public final class JPrimitiveType
extends JType

Java built-in primitive types. Instances of this class can be obtained as constants of JCodeModel, such as JCodeModel.BOOLEAN.

Method Summary

Modifier and Type	Method	Description
JClass	array()	Create an array type of this type.
JClass	boxify()	Obtains the wrapper class for this primitive type.
String	fullName()	Gets the full name of the type.
void	generate(JFormatter f)
JClass	getWrapperClass()	Deprecated. Use boxify().
boolean	isPrimitive()	Tell whether or not this is a built-in primitive type, such as int or void.
String	name()	Gets the name of this type.
JCodeModel	owner()	Gets the owner code model object.
JType	unboxify()	Deprecated. calling this method from JPrimitiveType would be meaningless, since it's always guaranteed to return this.
JExpression	unwrap(JExpression exp)	Do the opposite of the wrap method.
JExpression	wrap(JExpression exp)	Wraps an expression of this type to the corresponding wrapper class.

JPrimitiveType

JPrimitiveType(JCodeModel owner,
 String typeName,
 Class<?> wrapper)

Method Details

owner

public JCodeModel owner()

Description copied from class: JType

Gets the owner code model object.

Specified by:

owner in class JType

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.

name

public String name()

Description copied from class: JType

Gets the name of this type.

Specified by:

name in class JType

Returns:

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

isPrimitive

public boolean isPrimitive()

Description copied from class: JType

Tell whether or not this is a built-in primitive type, such as int or void.

Overrides:

isPrimitive in class JType

array

public JClass array()

Description copied from class: JType

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

Specified by:

array in class JType

Returns:

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

boxify

public JClass boxify()

Obtains the wrapper class for this primitive type. For example, this method returns a reference to java.lang.Integer if this object represents int.

Specified by:

boxify in class JType

unboxify

public JType unboxify()

Deprecated.

calling this method from JPrimitiveType would be meaningless, since it's always guaranteed to return this.

Description copied from class: JType

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".

Specified by:

unboxify in class JType

getWrapperClass

public JClass getWrapperClass()

Deprecated.

Use boxify().

wrap

public JExpression wrap(JExpression exp)

Wraps an expression of this type to the corresponding wrapper class. For example, if this class represents "float", this method will return the expression new Float(x) for the paramter x. REVISIT: it's not clear how this method works for VOID.

unwrap

public JExpression unwrap(JExpression exp)

Do the opposite of the wrap method. REVISIT: it's not clear how this method works for VOID.

generate

public void generate(JFormatter f)
