static

Returns the primitive array-class of the given primitive class name.

Parameters

name	Name of the class.

Returns: Class structure.

Definition at line 314 of file primitive.cpp.

classinfo * Primitive::get_arrayclass_by_type ( int type )

static

Parameters

type	Integer type of the class.

Returns: Class structure.

Definition at line 336 of file primitive.cpp.

Parameters

ch

Returns: Class structure.

Definition at line 266 of file primitive.cpp.

classinfo * Primitive::get_class_by_name ( Utf8String name )

static

Parameters

c	Class structure.

Returns: Integer type of the class.

Definition at line 370 of file primitive.cpp.

int Primitive::get_type_by_wrapperclass ( classinfo * c )

static

Returns: Integer type of the class.

void Primitive::initialize_table ( )

static

Fill the primitive type table with the primitive-type classes, array-classes and wrapper classes.

This is important in the VM startup.

We split this primitive-type table initialization because of annotations in the bootstrap classes.

But we may get a problem if we have annotations in:

java/lang/Object java/lang/Cloneable java/io/Serializable

Also see: loader_preinit and linker_preinit.

Definition at line 94 of file primitive.cpp.

void Primitive::post_initialize_table ( )

static

Finish the primitive-type table initialization.

In this step we set the vftbl of the primitive-type classes.

This is necessary because java/lang/Class is loaded and linked after the primitive types have been linked.

We have to do that in an extra function, as the primitive types are not stored in the classcache.

Definition at line 204 of file primitive.cpp.

imm_union Primitive::unbox ( java_handle_t * h )

static

Unbox a primitive of the given type.

If the type is an object, simply return it.

h	Handle of the Java object.

Returns: Unboxed value as union.

bool Primitive::unbox_typed	(	java_handle_t *	h,
		int	type,
		imm_union *	value
	)

static

Unbox a primitive of the given type.

Also checks if the boxed primitive type can be widened into the destination type. This conversion is done according to "The Java Language Specification, Third Edition, $5.1.2 Widening Primitive Conversion".

Parameters

h	Handle of the boxing Java object.
type	Destination type of the conversion.
value	Pointer to union where the resulting primitive value will be stored will.

Returns: True of the conversion is allowed, false otherwise.
