public ProgramPrefix getNextPrefixElement()

Description copied from interface: ProgramPrefix

return the next prefix element if no next prefix element is available an IndexOutOfBoundsException is thrown

Specified by:

getNextPrefixElement in interface ProgramPrefix

getLastPrefixElement

public ProgramPrefix getLastPrefixElement()

Specified by:

getPrefixElements in interface ProgramPrefix

expressionWithoutSideffects

private boolean expressionWithoutSideffects()

The method checks whether the expression in the synchronized prefix is either a local variable or a meta class reference (as local variables of this type are not supported by KeY, see return value for MetaClassReference.getKeYJavaType(Services, ExecutionContext).

Returns:

true iff the above stated condition holds.

getFirstActiveChildPos

public PosInProgram getFirstActiveChildPos()

Description copied from interface: ProgramPrefix

returns the position of the first active child

Specified by:

getFirstActiveChildPos in interface ProgramPrefix

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)
