registerPointerStmts

public void registerPointerStmts(StmtRegistrar registrar,
                        RegisterPointerStmtsVisitor v)

Description copied from class: ExtExpr

This method needs to ensure that: 1. For all expressions of reference type, there is a local node 2. That local node has been assigned to appropriately, based on the semantics of the expression 3. Exceptions have been assigned to the appropriate handlers (including exceptions that may be generated by this expression).

Specified by:

registerPointerStmts in interface AccrueExt

Overrides:

registerPointerStmts in class ExtExpr

numArgumentsOnResultStack

public int numArgumentsOnResultStack()

Description copied from interface: AccrueExt

During a dataflow analysis, when this term is encountered, how many arguments should there be on the expression result stack? For example, for an addition (e1 + e2) there will be two, one for each operand. For a field access (o.f) there will be one, the target of the access. In general, this will return a meaningful number only for expressions.

Specified by:

numArgumentsOnResultStack in interface AccrueExt

Overrides:

numArgumentsOnResultStack in class ExtExpr

Returns:

throwTypes

public java.util.Collection<ThrowableType> throwTypes(polyglot.types.TypeSystem ts,
                                             AnalysisContext context)

Description copied from class: ExtTerm

Get the collection of types of exceptions that might be thrown

Overrides:

throwTypes in class ExtTerm

Parameters:

ts - Polyglot type system

context - Data flow analysis context

Returns:

collection of types of exceptions that might be thrown

recordClassCastAnalysisResult

public void recordClassCastAnalysisResult(AnalysisUtil<?> autil)

mayThrowClassCastException

public boolean mayThrowClassCastException(AnalysisContext context)

flowDispatch

public <DFItem extends polyglot.visit.DataFlow.Item> java.util.Map<polyglot.visit.FlowGraph.EdgeKey,DFItem> flowDispatch(DataFlowDispatch<DFItem> d,
                                                                                                                DFItem dfIn,
                                                                                                                polyglot.visit.FlowGraph<DFItem> graph,
                                                                                                                polyglot.visit.FlowGraph.Peer<DFItem> peer)

Description copied from class: ExtTerm

Dispatch function. Subclasses of ExtTerm should override this method to invoke the appropriate method of DataFlowDispatch d. This helps extensions implement and extend data flow analyses.

Overrides:

flowDispatch in class ExtTerm

Returns:
