/**
@brief Initialize the application.
@return Zero if successful, or non-zero if not.
Load the IDL file into an internal data structure for future reference. Each non-virtual
class in the IDL corresponds to a table or view in the database, or to a subquery defined
in the IDL. Ignore all virtual tables and virtual fields.
Register a number of methods, some of them general-purpose and others specific for
particular classes.
The name of the application is given by the MODULENAME macro, whose value depends on
conditional compilation. The method names also incorporate MODULENAME, followed by a
dot, as a prefix.
The general-purpose methods are as follows (minus their MODULENAME prefixes):
- json_query
- transaction.begin
- transaction.commit
- transaction.rollback
- savepoint.set
- savepoint.release
- savepoint.rollback
For each non-virtual class, create up to eight class-specific methods:
- create (not for readonly classes)
- retrieve
- update (not for readonly classes)
- delete (not for readonly classes
- search (atomic and non-atomic versions)
- id_list (atomic and non-atomic versions)
The full method names follow the pattern "MODULENAME.direct.XXX.method_type", where XXX
is the fieldmapper name from the IDL, with every run of one or more consecutive colons
replaced by a period. In addition, the names of atomic methods have a suffix of ".atomic".
This function is called when the registering the application, and is executed by the
listener before spawning the drones.
