Constructor Detail

ThisReference

public ThisReference()

This reference.

ThisReference

public ThisReference(TypeReference outer)

This reference.

Parameters:

outer - a type reference.

ThisReference

public ThisReference(ExtList children)

Constructor for the transformation of COMPOST ASTs to KeY.

Parameters:

children - the children of this AST element as KeY classes. May contain: a TypeReference (as reference for the ThisReference) Comments

Method Detail

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 JavaSourceElement

Returns:

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

See Also:

JavaSourceElement.toSource(), JavaSourceElement.getStartPosition()

getFirstElementIncludingBlocks

public SourceElement getFirstElementIncludingBlocks()

Description copied from interface: SourceElement

Finds the source element that occurs first in the source.

Specified by:

getFirstElementIncludingBlocks in interface SourceElement

Overrides:

getFirstElementIncludingBlocks in class JavaSourceElement

Returns:

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

See Also:

SourceElement.getStartPosition()

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

getReferencePrefix

public ReferencePrefix getReferencePrefix()

Get reference prefix.

Specified by:

getReferencePrefix in interface ReferencePrefix

Returns:

the reference prefix.

getTypeReferenceCount

public int getTypeReferenceCount()

Get the number of type references in this container.

Specified by:

getTypeReferenceCount in interface TypeReferenceContainer

Returns:

the number of type references.

getTypeReferenceAt

public TypeReference getTypeReferenceAt(int index)

Specified by:

getTypeReferenceAt in interface TypeReferenceContainer

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.

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
