Constructor Detail

Case

public Case()

Case.

Case

public Case(Expression e)

Case.

Parameters:

e - an expression.

Case

public Case(Expression e,
            Statement[] body)

Case.

Parameters:

e - an expression.

body - a statement mutable list.

Case

public Case(ExtList children,
            Expression expr,
            PositionInfo pos)

Constructor for the transformation of COMPOST ASTs to KeY.

Parameters:

children - the children of this AST element as KeY classes. May contain: Comments a Statement (as the statement following case) Must NOT contain: an Expression indicating the condition of the case as there are classes that are Expression and Statement, so they might get mixed up. Use the second parameter of this constructor for the expression.

expr - the expression of the case

Method Detail

getChildCount

public int getChildCount()

Returns the number of children of this node.

Specified by:

getChildCount in interface NonTerminalProgramElement

Returns:

an int giving the number of children of this node

getChildAt

public ProgramElement getChildAt(int index)

Returns the child at the specified index in this node's "virtual" child array

Specified by:

getChildAt in interface NonTerminalProgramElement

Parameters:

index - an index into this node's "virtual" child array

Returns:

the program element at the given position

Throws:

java.lang.ArrayIndexOutOfBoundsException - if index is out of bounds

getExpressionCount

public int getExpressionCount()

Get the number of expressions in this container.

Specified by:

getExpressionCount in interface ExpressionContainer

Returns:

the number of expressions.

getExpressionAt

public Expression getExpressionAt(int index)

Specified by:

getExpressionAt in interface ExpressionContainer

getStatementCount

public int getStatementCount()

Get the number of statements in this container.

Specified by:

getStatementCount in interface StatementContainer

Returns:

the number of statements.

getStatementAt

public Statement getStatementAt(int index)

Specified by:

getStatementAt in interface StatementContainer

getExpression

public Expression getExpression()

Get expression.

Returns:

the expression.

getBody

public ImmutableArray<Statement> getBody()

The body may be empty (null), to define a fall-through. Attaching an EmptyStatement would create a single ";".

visit

public void visit(Visitor v)

calls the corresponding method of a visitor in order to perform some action/transformation on this element

Specified by:

visit in interface SourceElement

Parameters:

v - the Visitor

prettyPrint

public void prettyPrint(PrettyPrinter p)
                 throws java.io.IOException

Description copied from class: JavaSourceElement

Pretty printing the source element.

Specified by:

prettyPrint in interface SourceElement

Overrides:

prettyPrint in class JavaProgramElement

Parameters:

p - a pretty printer.

Throws:

java.io.IOException - occasionally thrown.
