Method Detail
-
getIR
public IR getIR(CGNode node)
- Specified by:
getIR
in interfaceSSAContextInterpreter
- Returns:
- the IR that models the method context, or null if it's an unmodelled native method
-
getNumberOfStatements
public int getNumberOfStatements(CGNode node)
- Specified by:
getNumberOfStatements
in interfaceSSAContextInterpreter
- Returns:
- the number of the statements in the IR, or -1 if it's an unmodelled native method.
-
understands
public boolean understands(CGNode node)
Description copied from interface:CHAContextInterpreter
Does this object understand the given method? The caller had better check this before inquiring on other properties.- Specified by:
understands
in interfaceCHAContextInterpreter
-
iterateNewSites
public Iterator<NewSiteReference> iterateNewSites(CGNode node)
- Specified by:
iterateNewSites
in interfaceRTAContextInterpreter
- Returns:
- an Iterator of the types that may be allocated by a given method in a given context.
-
iterateCallSites
public Iterator<CallSiteReference> iterateCallSites(CGNode node)
- Specified by:
iterateCallSites
in interfaceCHAContextInterpreter
- Returns:
- an Iterator of the call statements that may execute in a given method for a given context
-
recordFactoryType
public boolean recordFactoryType(CGNode node, IClass klass)
Description copied from interface:RTAContextInterpreter
record that the "factory" method of a node should be interpreted to allocate a particular class. TODO: this is a little ugly, is there a better place to move this?- Specified by:
recordFactoryType
in interfaceRTAContextInterpreter
- Returns:
- true iff a NEW type was recorded, false if the type was previously recorded.
-
iterateFieldsRead
public Iterator<FieldReference> iterateFieldsRead(CGNode node)
- Specified by:
iterateFieldsRead
in interfaceRTAContextInterpreter
- Returns:
- iterator of FieldReference
-
iterateFieldsWritten
public Iterator<FieldReference> iterateFieldsWritten(CGNode node)
- Specified by:
iterateFieldsWritten
in interfaceRTAContextInterpreter
- Returns:
- iterator of FieldReference
-
hasObjectArrayLoad
public boolean hasObjectArrayLoad(CGNode node)
-
hasObjectArrayStore
public boolean hasObjectArrayStore(CGNode node)
-
getCFG
public ControlFlowGraph<SSAInstruction,ISSABasicBlock> getCFG(CGNode N)
- Specified by:
getCFG
in interfaceSSAContextInterpreter
-
getDU
public DefUse getDU(CGNode node)
- Specified by:
getDU
in interfaceSSAContextInterpreter
- Returns:
- DefUse for the IR that models the method context, or null if it's an unmodelled native method
