public class JPrimitiveType
extends AbstractJType

Constructor Detail

JPrimitiveType

protected JPrimitiveType(@Nonnull
              JCodeModel aOwner,
              @Nonnull
              String sTypeName,

              boolean bUseValueOf)

Method Detail

owner

@Nonnull
public JCodeModel owner()

Description copied from interface: IJOwned

Gets the owner code model object.

Returns:

The owner and never null.

fullName

@Nonnull
public String fullName()

Description copied from class: AbstractJType

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 AbstractJType

Returns:

Strings like "int", "java.lang.String", "java.io.File[]". May be null for unnamed classes.

name

@Nonnull
public String name()

Description copied from class: AbstractJType

Gets the name of this type.

Specified by:

name in class AbstractJType

Returns:

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

isPrimitive

public boolean isPrimitive()

Description copied from class: AbstractJType

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

Overrides:

isPrimitive in class AbstractJType

Returns:

true if this is a primitive type

array

@Nonnull
public JArrayClass array()

Description copied from class: AbstractJType

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 AbstractJType

Returns:

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

boxify

@Nonnull
public AbstractJClass boxify()

Description copied from class: AbstractJType

If this class is a primitive type, return the boxed class. Otherwise return this.

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

Specified by:

boxify in class AbstractJType

Returns:

Never null

unboxify

@Deprecated
@Nonnull
public AbstractJType unboxify()

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

Description copied from class: AbstractJType

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 AbstractJType

Returns:

Never null

wrap

@Nonnull
public IJExpression wrap(@Nonnull
                        IJExpression aExpr)

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) or Float.valueOf(x) for the parameter x.
For void type it throws an IllegalStateException because this would lead to corrupt code!

Parameters:

aExpr - Expression to be wrapped

Returns:

The created expression. Never null

See Also:

useValueOf()

unwrap

@Nonnull
public IJExpression unwrap(@Nonnull
                          IJExpression aExpr)

Do the opposite of the wrap method. So for a Float object x it creates x.floatValue()
For void type it throws an IllegalStateException because this would lead to corrupt code!

Parameters:

aExpr - Expression to be unwrapped

Returns:

The created primitive value expression. Never null

useValueOf

public boolean useValueOf()

Returns:

true if valueOf should be used in wrap(IJExpression), false if new X(y) should be used there. Note: valueOf is faster in execution since it uses potentially built in caches of the objects.

useValueOf

public void useValueOf(boolean bUseValueOf)

Determine of valueOf should be used or not.

Parameters:

bUseValueOf - New value. true to enable usage of valueOf

generate

public void generate(@Nonnull
            JFormatter f)
