Request for notification when a class is prepared in the target VM. When an enabled ClassPrepareRequest is satisfied, an event set containing a ClassPrepareEvent will be placed on the EventQueue. The collection of existing ClassPrepareRequests is managed by the EventRequestManager 

Class preparation is defined in the Java Virtual Machine
Specification.

Restricts the events generated by this request to the
preparation of reference types for which the restricted regular
expression 'sourceNamePattern' matches one of the 'sourceNames' for
the reference type being prepared.
That is, if refType is the ReferenceType being prepared,
then there exists at least one stratum, call it 'someStratum'
on the list returned by
    refType.availableStrata();
such that a name on the list returned by
    refType.sourceNames(someStratam)
matches 'sourceNamePattern'.
Regular expressions are limited
to exact matches and patterns that begin with '*' or end with '*';
for example, "*.Foo" or "java.*".

 Not all targets support this operation. Use VirtualMachine.canUseSourceNameFilters() to determine if the operation is supported.
