Method Details

addElementToSequence

public static void addElementToSequence(Feature sequenceFeature,
 Element addedElement,
 Function<Element,Expression> expressionFactory)

Adds the element to the sequence using the ',' operator.

For example, if the passed sequence feature is the following: (requirement1.metadata, requirement2.metadata)
and the element parameter requirement3 is passed along with MetadataAccessExpressions.createMetadataAccessExpression(Element) factory, it will result in the following sequence: (requirement1.metadata, requirement2.metadata, requirement3.metadata)

Parameters:

sequenceFeature - root feature of the sequence

addedElement - element, which will be added to the sequence

getValue

public static List<Expression> getValue(OperatorExpression topExpression)

Extracts all non-operator expressions from a comma operator expression tree.

Parameters:

topExpression - the root operator expression

Returns:

list of contained expressions in sequence order

isCommaOperatorExpression

public static boolean isCommaOperatorExpression(@CheckForNull
 Expression expression)

Checks whether the given expression is a comma operator expression.

Parameters:

expression - the expression to check

Returns:

true if the expression uses the comma operator

createCommaOperatorExpression

public static OperatorExpression createCommaOperatorExpression(Supplier<ElementsFactory> factorySupplier)

Creates a new comma operator expression with two input parameters.

Parameters:

factorySupplier - supplier for the elements factory

Returns:

a new comma operator expression

createCommaOperatorExpression

public static OperatorExpression createCommaOperatorExpression(Expression first,
 Expression second)

Creates a comma operator expression combining two expressions.

Parameters:

first - the first expression

second - the second expression

Returns:

a new comma operator expression

createCommaOperatorExpression

@CheckForNull
public static OperatorExpression createCommaOperatorExpression(Expression... expressions)

Creates a comma operator expression from the given list of expressions. If no expressions are provided, this method returns null.

Parameters:

expressions - the expressions to combine using the comma operator

Returns:

a comma operator expression combining the given expressions, or null if the input is empty
