Constructor Detail

ContextInsensitiveSSAInterpreter

public ContextInsensitiveSSAInterpreter(AnalysisOptions options,
                                        ClassHierarchy cha)

Method Detail

getIR

public IR getIR(CGNode node,
                WarningSet warnings)

Specified by:

getIR in interface SSAContextInterpreter

Returns:

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

getNumberOfStatements

public int getNumberOfStatements(CGNode node,
                                 WarningSet warnings)

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 klass. 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 getCFG(CGNode N,
                               WarningSet warnings)

Specified by:

getCFG in interface CFGProvider

Parameters:

N - a call graph node

Returns:

a CFG that represents the node, or null if it's an unmodelled native method

getDU

public DefUse getDU(CGNode node,
                    WarningSet warnings)

Specified by:

getDU in interface SSAContextInterpreter
