JvmTaintTransferRelation

public JvmTaintTransferRelation(java.util.Map<Signature,java.util.Set<JvmTaintSource>> taintSources)

Create a taint transfer relation.

Parameters:

taintSources - a mapping from fully qualified names to taint sources

JvmTaintTransferRelation

public JvmTaintTransferRelation(java.util.Map<Signature,java.util.Set<JvmTaintSource>> taintSources,
                                java.util.Map<MethodSignature,JvmTaintTransformer> taintTransformers)

Method Detail

invokeMethod

public void invokeMethod(JvmAbstractState<SetAbstractState<JvmTaintSource>> state,
                         Call call,
                         java.util.List<SetAbstractState<JvmTaintSource>> operands)

Description copied from class: JvmTransferRelation

The default implementation computes join over its arguments.

Overrides:

invokeMethod in class JvmTransferRelation<SetAbstractState<JvmTaintSource>>

getAbstractDefault

public SetAbstractState<JvmTaintSource> getAbstractDefault()

Description copied from class: JvmTransferRelation
