public class PrimitiveType
extends PredefinedType

A PrimitiveType instance represents a primitive type as defined in the Java language. There are eight primitive types: boolean, byte, short, int, long, char, float, double.

Class PredefinedType provides public static final variables referring to the JavaType representation for primtive types.

Since:

JDO 1.0.1

Constructor.

Parameters:

clazz - the Class instance representing the type

Method Detail

isPrimitive

public boolean isPrimitive()

Returns true if this JavaType represents a primitive type.

Specified by:

isPrimitive in interface JavaType

Overrides:

isPrimitive in class AbstractJavaType

Returns:

true if this JavaTypre represents a primitive type; false otherwise.

isValue

public boolean isValue()

Returns true if this JavaType represents a type whoses values may be treated as values rather than refernces during storing.

Specified by:

isValue in interface JavaType

Overrides:

isValue in class AbstractJavaType

Returns:

true if this JavaType represents a value type; false otherwise.

getWrapperClassType

public WrapperClassType getWrapperClassType()

Returns the JavaType instance of the Java wrapper class that corresponds to this primitive type.

Returns:

the JavaType of the corresponding Java wrapper class.
