String value

functionsClass

Class<?> functionsClass

The class that contains all the name of functions that are supported by the language. The name of the functions are defined as String constants in the functions class. The class to provide can be any class but by convention, we would expect a class whose name is of type xxxConstants where xxx is the name of the corresponding language like for example SimpleConstants for the language camel-simple. The metadata of a given functions are retrieved directly from the annotation @Metadata added to the String constant representing its name and defined in the functions class.

Default:

void.class

operatorsClass

Class<?> operatorsClass

The class that contains all the name of operators that are supported by the language. The name of the operators are defined as String constants in the operators class. The class to provide can be any class but by convention, we would expect a class whose name is of type xxxOperatorConstants where xxx is the name of the corresponding language like for example SimpleOperatorConstants for the language camel-simple. The metadata of a given operator are retrieved directly from the annotation @Metadata added to the String constant representing its name and defined in the operators class.
