Field Details

nestedVariable

private AbstractVariable nestedVariable

Constructor Details

Variable

Variable()

Constructor for serialization.

Variable

public Variable(AbstractVariable nestedVariable)

The constructor for this class.

Parameters:

nestedVariable - The nested variable should be embedded in the current constraint.

Method Details

getVariable

public AbstractVariable getVariable()

Getter for the nestedVariable.

Returns:

The nested variable should not be null.

inferDatatype

public IDatatype inferDatatype()
                        throws CSTSemanticException

Description copied from class: ConstraintSyntaxTree

Infers the datatype of the subtree represented by this object.

Specified by:

inferDatatype in class ConstraintSyntaxTree

Returns:

the data type

Throws:

CSTSemanticException - Will be thrown if parameters of (sub-) trees do not fit together.

accept

public void accept(IConstraintTreeVisitor visitor)

Description copied from class: ConstraintSyntaxTree

Visiting method for the visitor.
This method is used for saving this model element.

Specified by:

accept in class ConstraintSyntaxTree

Parameters:

visitor - The visitor, which should save this model element.

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getAttributesCount

public int getAttributesCount()

Description copied from class: ConstraintSyntaxTree

Returns the number of attributes.

Specified by:

getAttributesCount in interface IAttributeAccess

Overrides:

getAttributesCount in class ConstraintSyntaxTree

Returns:

the number of attributes

getAttribute

public Attribute getAttribute(int index)

Description copied from class: ConstraintSyntaxTree

Returns a specific attribute.

Specified by:

getAttribute in interface IAttributeAccess

Overrides:

getAttribute in class ConstraintSyntaxTree

Parameters:

index - the index of the attribute

Returns:

the attribute

toString

public String toString()

Overrides:

toString in class Object

getQualifier

public ConstraintSyntaxTree getQualifier()

Returns the qualifier for accessing the variable, e.g., an expression to be put before. For usual variables, the qualifier is always null.

Returns:

the qualifier (may be null)

getResolved

public IDecisionVariable getResolved()

Returns the resolved decision variable.

Returns:

the decision variable (may be null)

isSemanticallyEqual

public boolean isSemanticallyEqual(ConstraintSyntaxTree otherTree)

Description copied from class: ConstraintSyntaxTree

Checks whether this ConstraintSyntaxTree is semantically equal to another ConstraintSyntaxTree. Attention:This method is not fully supported by all operations and sub classes.

Overrides:

isSemanticallyEqual in class ConstraintSyntaxTree

Parameters:

otherTree - Another cst to check whether it is semantically equal to this cst.

Returns:

true if both trees are semantically equal, false otherwise.
