Constructor Details

UnionClassImpl

public UnionClassImpl()

Constructor for UnionClassImpl.

Method Details

add

public void add(DataClass dataClass)
         throws IllegalEditException

Adds an additional DataClass to the list of data classes

Specified by:

add in interface UnionClass

Parameters:

dataClass - The new data class. If the data class is already in the list the new one will be ignored.

Throws:

IllegalEditException

checkFinishEditing

public void checkFinishEditing()
                        throws ClassHierarchyConsistencyException

This method only checks if it is possible to finish the class and does not change any internal status. To initialize internal caches use the method AbstractDataClassImpl.finishEditing().

Sub classes are allowed to overwrite this method with own code but they must follow some instructions. It is very important to call the AbstractDataClassImpl.checkFinishEditing() method in the super class. This can be done before or after the own check methods. But it is advisable to implement the methods like in AbstractDataClassImpl.finishEditing() where first the super class is called. For example:

protected void checkFinishEditing() throws ClassHierarchyConsistencyException { super.checkFinishEditing(); // put your code here }

Overrides:

checkFinishEditing in class AbstractDataClassImpl

Throws:

ClassHierarchyConsistencyException

See Also:

• AbstractDataClassImpl.finishEditing()

createSystemSubClasses

protected void createSystemSubClasses()

createSystemSubClasses.

Specified by:

createSystemSubClasses in class AbstractDataClassImpl

getClasses

public DataClass[] getClasses()

getClasses.

Specified by:

getClasses in interface UnionClass

Returns:

an array of all DataClasses.

See Also:

• UnionClass.add(DataClass)
• UnionClass.remove(DataClass)

hasClass

public boolean hasClass(DataClass dataClass)

Checks if the given DataClass dataClass is a member of the union.

Specified by:

hasClass in interface UnionClass

Parameters:

dataClass - The DataClass that should be checked.

Returns:

true if the dataClass is a member of the union.

includeClass

public boolean includeClass(DataClass other)

This method checks if the data class contains a reference to another data class.

Some data classes contain other data classes. For example, AggregateClasses contain as attribute type other data classes or CollectionClasses have one element type which is also a data class.

To prevent an infinite loop, this method does not recursive navigates through all element classes. Only the element of the class are checked but not, if the elements include the given anotherClass.

Specified by:

includeClass in interface DataClass

Overrides:

includeClass in class AbstractDataClassImpl

Parameters:

other - The data class that has to be checked for references

Returns:

true if the data class contains a reference to the give anotherClass.

isUnion

public boolean isUnion()

isUnion.

Specified by:

isUnion in interface DataClass

Overrides:

isUnion in class AbstractDataClassImpl

Returns:

true if the data class can be casted to UnionClass

remove

public void remove(DataClass dataClass)
            throws IllegalEditException

Removes a DataClass from the list of data classes. If the data class is not in the list of data classes nothing will happen.

Specified by:

remove in interface UnionClass

Parameters:

dataClass - The data class that should be removed.

Throws:

IllegalEditException

newObject

public DataObject newObject()
                     throws IllegalInstantiationException

Creates a new DataObject and initialize it. DataObjects can not be created directly because they depend on the DataClass that defines the object.

The creation of a new object is only be possible if DataClass.checkInstantiability() throws no exception.

Specified by:

newObject in interface DataClass

Overrides:

newObject in class AbstractDataClassImpl

Returns:

a new DataObject

Throws:

IllegalInstantiationException - is thrown if it is not possible to create an object this data class

createSubclass

public DataClass createSubclass(String name)

This method creates none system sub classes that are defined by the user. It is not possible to create sub-classes for abstract system classes. In that case a IllegalInstantiationException will be thrown.

Each data class has a unique name. This name must be given to this method. If the name already exists, a NameAlreadyExistsException will be thrown. The name can be used to access the data class from the data model by using the method Model.getClass(String).

The class is automatically added to the model. To remove the class again you must use the method Model.removeClass(String).

Specified by:

createSubclass in interface DataClass

Overrides:

createSubclass in class AbstractDataClassImpl

Parameters:

name - The uniqe name of the new sub class.

Returns:

The new sub class.

See Also:

• Model.removeClass(String)

conformToModel

public void conformToModel(Model other)

Checks the list of data classes whether they conform to given model. If DataClasses are used which are present in the given model but with different reference, they will be replaced.

Parameters:

other - The other data model to which this union class should conform to
