Constructor Detail

ParenthesizedExpression

public ParenthesizedExpression(ExtList children)

Constructor for the transformation of COMPOST ASTs to KeY.

Parameters:

children - the children of this AST element as KeY classes. In this case the order of the children is IMPORTANT. May contain: several of Expression (should be one, the first is taken as parenthesized expression), Comments

ParenthesizedExpression

public ParenthesizedExpression(Expression child)

Method Detail

getChildCount

public int getChildCount()

Returns the number of children of this node.

Specified by:

getChildCount in interface NonTerminalProgramElement

Overrides:

getChildCount in class Operator

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

Overrides:

getChildAt in class Operator

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

getArity

public int getArity()

Get arity.

Specified by:

getArity in class Operator

Returns:

the int value.

getPrecedence

public int getPrecedence()

Get precedence.

Specified by:

getPrecedence in class Operator

Returns:

the int value.

getNotation

public int getNotation()

Get notation.

Specified by:

getNotation in class Operator

Returns:

the int value.

getFirstElement

public SourceElement getFirstElement()

Description copied from class: JavaSourceElement

Finds the source element that occurs first in the source. The default implementation returns this element, which is correct for all terminal program elements, and many non terminals such as statements and prefixed operators.

Specified by:

getFirstElement in interface SourceElement

Overrides:

getFirstElement in class Operator

Returns:

the first source element in the syntactical representation of this element, may be equals to this element.

See Also:

JavaSourceElement.toSource(), JavaSourceElement.getStartPosition()

getLastElement

public SourceElement getLastElement()

Description copied from class: JavaSourceElement

Finds the source element that occurs last in the source. The default implementation returns this element, which is correct for all terminal program elements, and many non terminals such as statements and prefixed operators.

Specified by:

getLastElement in interface SourceElement

Overrides:

getLastElement in class Operator

Returns:

the last source element in the syntactical representation of this element, may be equals to this element.

See Also:

JavaSourceElement.toSource(), JavaSourceElement.getEndPosition()

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 w)
                 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:

w - a pretty printer.

Throws:

java.io.IOException - occasionally thrown.

getReferencePrefix

public ReferencePrefix getReferencePrefix()

We do not have a prefix, so fake it! This way we implement ReferencePrefix

Specified by:

getReferencePrefix in interface ReferencePrefix

setReferencePrefix

public ReferencePrefix setReferencePrefix(ReferencePrefix r)

getKeYJavaType

public KeYJavaType getKeYJavaType(Services javaServ,
                                  ExecutionContext ec)

Description copied from interface: Expression

returns the KeYJavaType of an expression

Specified by:

getKeYJavaType in interface Expression

Specified by:

getKeYJavaType in class Operator
