Method Detail

setAllocNode

public void setAllocNode(AllocSiteNode allocNode,
                ConstructorContext constructorContext)

Description copied from interface: ExtAlloc

Set the AllocSiteNode representing the allocation of a new object (within the specific constructor context).

Specified by:

setAllocNode in interface ExtAlloc

getAllocNode

public AllocSiteNode getAllocNode(ConstructorContext constructorContext)

Description copied from interface: ExtAlloc

Get the AllocSiteNode representing the allocation of a new object (within the specific constructor context).

Specified by:

getAllocNode in interface ExtAlloc

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

mayBeNull

public boolean mayBeNull(AnalysisContext context)

Overrides:

mayBeNull in class ExtExpr

recordPreciseExResults

public void recordPreciseExResults(AnalysisContext context,
                          java.util.Set<ThrowableType> throwTypes,
                          boolean canTerminateNormally)

Specified by:

recordPreciseExResults in interface ExtProcedureCall

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

Specified by:

throwTypes in interface ExtProcedureCall

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

canTerminateNormally

public boolean canTerminateNormally(AnalysisContext context)

Specified by:

canTerminateNormally in interface ExtProcedureCall

flowDispatch

public <DFItem extends polyglot.visit.DataFlow.Item> java.util.Map<polyglot.visit.FlowGraph.EdgeKey,DFItem> flowDispatch(DataFlowDispatch<DFItem> dataflow,
                                                                                                                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:

setCallSiteNode

public void setCallSiteNode(CallSiteNode callSiteNode)

Specified by:

setCallSiteNode in interface ExtProcedureCall

getCallSiteNode

public CallSiteNode getCallSiteNode()

Specified by:

getCallSiteNode in interface ExtProcedureCall
