Method Detail

call_function

public Object call_function(String function_name,
                            Object... args)
                     throws XtumlException

Description copied from interface: LOAD

Invoke an xtUML domain function in the same component which originally created the instance of LOAD.

Specified by:

call_function in interface LOAD

Parameters:

function_name - The name of the domain function to invoke

args - The argument list in modeled order

Returns:

The result of the function invocation or null for functions with void return type

Throws:

XtumlException - if the a domain function could not be found with the given names, or if the number of arguments or types of arguments mismatch

create

public Object create(String key_letters)
              throws XtumlException

Description copied from interface: LOAD

Create an xtUML class instance.

Specified by:

create in interface LOAD

Parameters:

key_letters - the key letters of the xtUML class

Returns:

an instance handle to the newly created class instance

Throws:

XtumlException - if no class with matching key letters can be found in the component

load

public void load(String java_class,
                 String[] args)
          throws XtumlException

Description copied from interface: LOAD

Create a new loader with a given set of arguments and kick off the loading process. An instance of the class specified by the java_class parameter is created. The specified class is expected to implement the IGenericLoader interface. Once created, the load method of the loader will be invoked, passing args and an instance of the LOAD class to link call back in to the instance population.

Specified by:

load in interface LOAD

Parameters:

java_class - the fully qualified class name of the loader class to create

args - the list of arguments to pass to the loader class

Throws:

XtumlException - if the class specified by java_class cannot be loaded or if it does not implement the IGenericLoader interface

relate

public void relate(Object inst1,
                   Object inst2,
                   int rel_num,
                   String phrase)
            throws XtumlException

Description copied from interface: LOAD

Relate two xtUML instances together across the given relationship. For non-reflexive relationships, inst1 and inst2 are interchangeable and the value of phrase has no effect. It may be null. For reflexive relationships, inst1 and inst2 will "read across" according to the value of phrase with the same semantics as OAL.

Specified by:

relate in interface LOAD

Parameters:

inst1 - the first instance to relate

inst2 - the second instance to relate

rel_num - the relationship number to create

phrase - the text phrase used to disambiguate relates of reflexive relationships

Throws:

XtumlException - if the relationship specified does not exist between inst1 and inst2 or if the act of relating the instances results in a model integrity violation

relate_using

public void relate_using(Object inst1,
                         Object inst2,
                         Object link,
                         int rel_num,
                         String phrase)
                  throws XtumlException

Description copied from interface: LOAD

Relate three xtUML instances together across the given associative relationship. For non-reflexive relationships, inst1 and inst2 are interchangeable and the value of phrase has no effect. It may be null. For reflexive relationships, inst1 and inst2 will "read across" according to the value of phrase with the same semantics as OAL.

Specified by:

relate_using in interface LOAD

Parameters:

inst1 - the first instance to relate

inst2 - the second instance to relate

link - the associative instance to relate

rel_num - the relationship number to create

phrase - the text phrase used to disambiguate relates of reflexive relationships

Throws:

XtumlException - if the relationship specified does not exist between inst1 and inst2 or if the act of relating the instances results in a model integrity violation

set_attribute

public void set_attribute(Object instance,
                          String attribute_name,
                          Object value)
                   throws XtumlException

Description copied from interface: LOAD

Set the value of an attribute on an instance of an xtUML class.

Specified by:

set_attribute in interface LOAD

Parameters:

instance - the model class instance

attribute_name - the name of the attribute to set

value - the value to assign to the specified attribute

Throws:

XtumlException - if the specified attribute does not exist on the class or if the type of the passed value is not compatible with the attribute type
