Method Details

getEdgeTransferFunction

public UnaryOperator<PrefixVariable> getEdgeTransferFunction(InstanceKeySite src,
 InstanceKeySite dst)

Specified by:

getEdgeTransferFunction in interface ITransferFunctionProvider<InstanceKeySite,PrefixVariable>

Returns:

the transfer function from OUT_src -> EDGE_<src,dst>

getMeetOperator

public AbstractMeetOperator<PrefixVariable> getMeetOperator()

Description copied from interface: ITransferFunctionProvider

TODO: perhaps this should go with a Lattice object instead. TODO: provide an API to allow composition of the meet operator with the flow operator for a given block, as an optimization?

Specified by:

getMeetOperator in interface ITransferFunctionProvider<InstanceKeySite,PrefixVariable>

getNodeTransferFunction

public UnaryOperator<PrefixVariable> getNodeTransferFunction(InstanceKeySite node)

Specified by:

getNodeTransferFunction in interface ITransferFunctionProvider<InstanceKeySite,PrefixVariable>

Returns:

the transfer function from IN_node -> OUT_node

hasEdgeTransferFunctions

public boolean hasEdgeTransferFunctions()

Specified by:

hasEdgeTransferFunctions in interface ITransferFunctionProvider<InstanceKeySite,PrefixVariable>

Returns:

true if this provider provides edge transfer functions

hasNodeTransferFunctions

public boolean hasNodeTransferFunctions()

Specified by:

hasNodeTransferFunctions in interface ITransferFunctionProvider<InstanceKeySite,PrefixVariable>

Returns:

true if this provider provides node transfer functions
