AttributesCheckVisitor

private AttributesCheckVisitor(ReasoningResult result,
                               AttributeValues values)

Creates a new visitor storing the given instances for processing.

Parameters:

values - the attribute values used as basis for the check (may be null)

result - the reasoning results (may be modified as a side effect)

Method Detail

check

public static boolean check(Configuration configuration,
                            ReasonerConfiguration reasonerConfiguration,
                            ReasoningResult result)

Checks the given configuration with respect to values and adjusts result if required.

Parameters:

configuration - the configuration to be checked (will not be modified)

reasonerConfiguration - the configuration holding the attribute values (may be null)

result - the reasoning results (may be modified as a side effect)

Returns:

true if the configuration is valid, false else

check

public static boolean check(Configuration configuration,
                            AttributeValues values,
                            ReasoningResult result)

Checks the given configuration with respect to values and adjusts result if required.

Parameters:

configuration - the configuration to be checked (will not be modified)

values - the attribute values used as basis for the check (may be null)

result - the reasoning results (may be modified as a side effect)

Returns:

true if the configuration is valid, false else

isValid

public boolean isValid()

Returns whether the given configuration is valid with respect to the given set of attributes and the actual values of the attributes.

Returns:

true if the configuration is valid, false else

visitConfiguration

public void visitConfiguration(Configuration configuration)

Description copied from interface: IConfigurationVisitor

Visits a configuration.

Specified by:

visitConfiguration in interface IConfigurationVisitor

Parameters:

configuration - the configuration to visit

visitDecisionVariable

public void visitDecisionVariable(IDecisionVariable variable)

Description copied from interface: IConfigurationVisitor

Visits a decision variable.

Specified by:

visitDecisionVariable in interface IConfigurationVisitor

Parameters:

variable - the decision variable to visit

checkDecisionVariable

private boolean checkDecisionVariable(IDecisionVariable variable)

Checks a single variable.

Parameters:

variable - the configuration value to be checked

Returns:

true if the configuration is valid, false else

getQualifiedName

private static java.lang.String getQualifiedName(IDecisionVariable variable)

Returns the qualified name of the given decision variable.

Parameters:

variable - the qualified name of the given decision variable

Returns:

the qualified name

checkDecisionVariable

private boolean checkDecisionVariable(IDecisionVariable attribute,
                                      IAssignmentState state)

Checks a single variable.

Parameters:

attribute - the variable representing the attribute

state - the assignment state of the variable being attributed by attribute

Returns:

true if the configuration is valid, false else

createMessage

public static Message createMessage(java.lang.String variableName,
                                    java.lang.String attributeName,

                                    ModelElement conflictingModelElement)

Creates the error message in case that an attribute assignment is missing.

Parameters:

variableName - the name of the variable causing the error

attributeName - the name of the required attribute

value - the value of the required attribute

conflictingModelElement - the model element representing the conflict (may be null if irrelevant)

Returns:

the message instance
