Method Summary

Modifier and Type	Method and Description
void	action(UMod.ClassDef cd) Is possibly called MORE THAN once for each object.
void	action(UMod.FieldDef fd) Descend to field value: 1) read object into "model" 2) set curfd to field 3) call match on the type
void	action(UMod.T_power type)
void	action(UMod.T_reference type)
void	action(UMod.T_seq type)
static Object	getFieldValue(Object o, UMod.FieldDef fd) Reads the content of a given field by applying java.lang.reflect methods.
UMod.ClassDef	getSpecialization(Object o) Finds the most specialized UMOd class definition for a certain object.
void	matchModel(UMod.ClassDef cd, Object o)
void	modelAction(Object o) Action for each model object, may be over-ridden by user of this Visitor.
protected void	visitFields(UMod.ClassDef cd) Descend to fields of the current model "model"; this is done ONLY ONCE for each model. Fields of superclass are visited BEFORE All fields are visited via their "action()" method This in turn calls "match()" on the TYPE of the field, which finally leads back to a match of the class definition.

Method Detail

matchModel

public void matchModel(UMod.ClassDef cd,
                       Object o)

getFieldValue

public static Object getFieldValue(Object o,
                                   UMod.FieldDef fd)

Reads the content of a given field by applying java.lang.reflect methods.

getSpecialization

public UMod.ClassDef getSpecialization(Object o)

Finds the most specialized UMOd class definition for a certain object. Uses the naming!

modelAction

public void modelAction(Object o)

Action for each model object, may be over-ridden by user of this Visitor. Is possibly called MORE THAN once for each object, before descending to the fields. May read "curfd", "curcd", "referingObject" as the objects and umod definitions which LEAD TO visiting this model object.

action

public void action(UMod.ClassDef cd)

Is possibly called MORE THAN once for each object. Calls "modelAction()" and then descends to the fields.
reads global field "model" and writes "referingObject".

Overrides:

action in class UMod.Visitor

visitFields

protected void visitFields(UMod.ClassDef cd)

Descend to fields of the current model "model"; this is done ONLY ONCE for each model.
Fields of superclass are visited BEFORE
All fields are visited via their "action()" method
This in turn calls "match()" on the TYPE of the field, which finally leads back to a match of the class definition.

action

public void action(UMod.FieldDef fd)

Descend to field value:
1) read object into "model"
2) set curfd to field
3) call match on the type

Overrides:

action in class UMod.Visitor

action

public void action(UMod.T_reference type)

Overrides:

action in class UMod.Visitor

action

public void action(UMod.T_seq type)

Overrides:

action in class UMod.Visitor

action

public void action(UMod.T_power type)

Overrides:
