-
- All Implemented Interfaces:
IProbeArrayStrategy
class InterfaceFieldProbeArrayStrategy extends java.lang.Object implements IProbeArrayStrategy
This strategy for Java 8 interfaces adds a static method requesting the probe array from the runtime, a static field to hold the probe array and adds code for its initialization into interface initialization method.
