Constructor Detail

TemporaryAttributesConfiguration

public TemporaryAttributesConfiguration(Project project,
                                        AttributeValues values,
                                        boolean group)

Creates a new configuration for the given project.
Please take a look in VarModel#addProject(Project) for more information.

Parameters:

project - The project, where this configuration belongs to. This project should already be registered at the VarModel

values - the attributes with values

group - group the attributes

Method Detail

convert

private boolean convert(boolean group,
                        boolean force)

Converts values to a group or non-group attribute values configuration. Converting to a grouped configuration may imply data loss.

Parameters:

group - convert to a group or non-group configuration

force - the execution (initial call)

Returns:

true if the conversion was done, false else

addAttribute

private void addAttribute(Attribute attribute)

Adds the given attribute and its values to this configuration.

Parameters:

attribute - the attribute to add

convert

public boolean convert(boolean group)

Converts values to a group or non-group attribute values configuration. Converting to a grouped configuration may imply data loss.

Parameters:

group - convert to a group or non-group configuration

Returns:

true if the conversion was done, false else

sameGroup

private boolean sameGroup(Attribute attr1,
                          Attribute attr2)

Returns whether two given attributes are in the same group, i.e. same (non-qualified) name and same type.

Parameters:

attr1 - the first attribute

attr2 - the same attribute

Returns:

true if attr1 and attr2 are in the same group, false else

addAttributeDecision

public void addAttributeDecision(Attribute attribute,
                                 Value value)
                          throws ConfigurationException

Adds an attribute decision to this configuration. This method is a specific functionality for user interaction. Subclass this class and make it accessible if needed, otherwise it may break the value protection provided by this class.

Parameters:

attribute - the attribute for which the decision shall be created

value - the value of the attribute (may be null)

Throws:

ConfigurationException - in case of type conflicts

clear

public void clear()

Clears all decisions.

Overrides:

clear in class Configuration

removeDecision

public boolean removeDecision(IDecisionVariable variable)

Remove a specific decision.

Overrides:

removeDecision in class Configuration

Parameters:

variable - the decision to be removed

Returns:

true if this operation was successful, false else

refreshed

public void refreshed(Configuration config)

In case that the configuration was refreshed.

Parameters:

config - the new configuration

valueChanged

public void valueChanged(IDecisionVariable changedVariable,
                         Value oldValue)

To be called when a value changed.

Parameters:

changedVariable - the changed variable carrying the new value

oldValue - the old value
