Some examples of where values may be accessed:

ObjectReference.getValue(com.sun.jdi.Field)ObjectReference.getValue(Field)	- value of a field
StackFrame.getValue(com.sun.jdi.LocalVariable)StackFrame.getValue(LocalVariable)	- value of a variable
VirtualMachine.mirrorOf(double)VirtualMachine.mirrorOf(double)	- created in the target VM by the JDI client
com.sun.jdi.event.ModificationWatchpointEvent.valueToBeModificationWatchpointEvent.valueToBe()	- returned with an event

The following table illustrates which subinterfaces of Value are used to mirror values in the target VM --

Subinterfaces of PrimitiveValue
Kind of value	For example - expression in target	Is mirrored as an instance of	Type of value Value.type() Value.type()
a boolean	true	BooleanValue	BooleanType
a byte	(byte)4	ByteValue	ByteType
a char	'a'	CharValue	CharType
a double	3.1415926	DoubleValue	DoubleType
a float	2.5f	FloatValue	FloatType
an int	22	IntegerValue	IntegerType
a long	1024L	LongValue	LongType
a short	(short)12	ShortValue	ShortType
a void		VoidValue	VoidType
Subinterfaces of ObjectReference
Kind of value	For example - expression in target	Is mirrored as an instance of	Type of value Value.type() Value.type()
a class instance	this	ObjectReference	ClassType
an array	new int[5]	ArrayReference	ArrayType
a string	"hello"	StringReference	ClassType
a thread	Thread.currentThread()	ThreadReference	ClassType
a thread group	Thread.currentThread()   .getThreadGroup()	ThreadGroupReference	ClassType
a java.lang.Class instance	this.getClass()	ClassObjectReference	ClassType
a class loader	this.getClass()   .getClassLoader()	ClassLoaderReference	ClassType
