Detailed Description

A field being emitted by a deparser.

Member Function Documentation

apply()

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

overridevirtual

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

Reimplemented from P4::P4Tools::TraceEvent.

evaluate()

const Emit * P4::P4Tools::TraceEvents::Emit::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.

print()

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

overrideprotectedvirtual

Prints this trace event to the given ostream.

Implements P4::P4Tools::TraceEvent.

subst()

const Emit * P4::P4Tools::TraceEvents::Emit::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.

Reimplemented from P4::P4Tools::TraceEvent.
