Constructor Details

AggregateClassImpl

public AggregateClassImpl()

Constructor for AggregateClassImpl.

AggregateClassImpl

protected AggregateClassImpl(String name)

Constructor for AggregateClassImpl.

Parameters:

name - a String object

Method Details

createSubclass

public DataClass createSubclass(String name)
                         throws ApplicationError,
IllegalInstantiationException,
NameAlreadyExistsException

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.

Throws:

IllegalInstantiationException

NameAlreadyExistsException

ApplicationError

See Also:

• Model.removeClass(String)

addAttribute

public void addAttribute(String attributeName,
 DataClass attributeType)
                  throws NameAlreadyExistsException,
IllegalEditException

Adds an attribute an the end of the attribute list.

Specified by:

addAttribute in interface AggregateClass

Parameters:

attributeName - a String object

attributeType - a DataClass object

Throws:

NameAlreadyExistsException

IllegalEditException - if any.

containsAttribute

public boolean containsAttribute(String attributeName)

Checks if the given attribute name is visible in this class.

Specified by:

containsAttribute in interface AggregateClass

Parameters:

attributeName - a String object

Returns:

true if the given attribute name exists in this or in one of the parent AggregateClasses.

createSystemSubClasses

protected void createSystemSubClasses()

createSystemSubClasses.

Specified by:

createSystemSubClasses in class AbstractDataClassImpl

finishEditing

public void finishEditing()
                   throws ClassHierarchyConsistencyException

To instantiate classes it is necessary to know if the class can be edited further. Only finished classes can be instantiated. Therefore, it is necessary to call this method to tell the system that the class is ready defined. Nevertheless, finishing a class can fail because of an inconsistency in the class hierarchy. One of the superclasses is not consistence with this class.

The finishing process is distinguished into two parts:

1. it is checked if it is possible to finish the class
2. the class is finished

Therefore, the method AbstractDataClassImpl.finishEditing() first calls the method AbstractDataClassImpl.checkFinishEditing(). Sub classes can overwrite both methods but must follow the instructions describe now.

Sub classes are allowed to overwrite this method to initialize the class, e.g., create internal caches. But the methods must first call the method AbstractDataClassImpl.finishEditing() in the super class. For example:

public void finishEditing() throws ClassHierarchyConsistencyException { super.finishEditing(); // put your own finishing code here }

Specified by:

finishEditing in interface DataClass

Overrides:

finishEditing in class AbstractDataClassImpl

Throws:

ClassHierarchyConsistencyException - if any.

See Also:

• DataClass.finishEditing()
• AbstractDataClassImpl.checkFinishEditing()
