Interface CmmnEngineLookup

public interface CmmnEngineLookup

Represents a strategy for building or looking up a CmmnEngine.

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.CmmnEngineLookup 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 be invoked first.

Since:

6.6.1
