Detailed Description

Denotes a successful extract call. Will provide information which header was successfully extracted and the offset it was extracted at.

Member Function Documentation

apply()

const ExtractSuccess * P4::P4Tools::TraceEvents::ExtractSuccess::apply ( Transform & visitor ) const

overridevirtual

Applies the given IR transform to the expressions in this trace event.

Reimplemented from P4::P4Tools::TraceEvent.

evaluate()

const ExtractSuccess * P4::P4Tools::TraceEvents::ExtractSuccess::evaluate ( const Model & model, bool doComplete ) const

nodiscardoverridevirtual

Evaluates expressions in the body of this trace event for their concrete value in the given model. A BUG occurs if there are any variables that are unbound by the given model.

Reimplemented from P4::P4Tools::TraceEvent.

getExtractedHeader()

const IR::Expression * P4::P4Tools::TraceEvents::ExtractSuccess::getExtractedHeader ( ) const

nodiscard

Returns

the extracted header label stored in this class.

getOffset()

int P4::P4Tools::TraceEvents::ExtractSuccess::getOffset ( ) const

nodiscard

Returns

the offset stored in this class.

print()

void P4::P4Tools::TraceEvents::ExtractSuccess::print ( std::ostream & ) const

overrideprotectedvirtual

Prints this trace event to the given ostream.

Implements P4::P4Tools::TraceEvent.

subst()

const ExtractSuccess * P4::P4Tools::TraceEvents::ExtractSuccess::subst ( const SymbolicEnv & env ) const

nodiscardoverridevirtual

Substitutes state variables in the body of this trace event for their symbolic value in the given symbolic environment. Variables that are unbound by the given environment are left untouched.
