Interface ProcessEngineLookup

All Known Subinterfaces:

ProcessEngineLookup

All Known Implementing Classes:

LocalProcessEngineLookup

public interface ProcessEngineLookup

Represents a strategy for building or looking up a ProcessEngine.

Implementations of this class are looked up using the Java SE 6 ServiceLoader facilities. Users of this class that provide a custom implementation, must declare it in a file named META-INF/services/org.flowable.cdi.spi.ProcessEngineLookup in order for it to be found.

Each implementation declares a "precedence". The precedence controls the order in which the resolved implementations will be invoked. (See: getPrecedence().) Implementations with a higher precedence will we invoked first.

Method Detail

getPrecedence

int getPrecedence()

Determines the ordering in which implementations are invoked. Implementations with a high ordering are invoked first.

getProcessEngine

ProcessEngine getProcessEngine()

This method will only be called once by the FlowableExtension, at startup

Returns:

a ProcessEngine

ungetProcessEngine

void ungetProcessEngine()

This method will only be called once by the FlowableExtension, at shutdown
