ContextInsensitiveSSAInterpreter

public ContextInsensitiveSSAInterpreter(AnalysisOptions options,
 IAnalysisCacheView cache)

Method Details

getIR

public IR getIR(CGNode node)

Specified by:

getIR in interface SSAContextInterpreter

Returns:

the IR that models the method context, or null if it's an unmodelled native method

getIRView

public IRView getIRView(CGNode node)

Specified by:

getIRView in interface SSAContextInterpreter

getNumberOfStatements

public int getNumberOfStatements(CGNode node)

Specified by:

getNumberOfStatements in interface SSAContextInterpreter

Returns:

the number of the statements in the IR, or -1 if it's an unmodelled native method.

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 interface RTAContextInterpreter

Overrides:

recordFactoryType in class ContextInsensitiveRTAInterpreter

Returns:

true iff a NEW type was recorded, false if the type was previously recorded.

getCFG

public ControlFlowGraph<SSAInstruction, ISSABasicBlock> getCFG(CGNode N)

Specified by:

getCFG in interface SSAContextInterpreter

getDU

public DefUse getDU(CGNode node)

Specified by:

getDU in interface SSAContextInterpreter

Returns:

DefUse for the IR that models the method context, or null if it's an unmodelled native method
