static P4RuntimeAPI	analyze (const IR::P4Program program, const IR::ToplevelBlock evaluatedProgram, ReferenceMap refMap, TypeMap typeMap, P4RuntimeArchHandlerIface *archHandler, cstring arch)

Detailed Description

An analyzer which translates the information available in the P4 IR into a representation of the control plane API which is consumed by P4Runtime.

Member Function Documentation

void P4::ControlPlaneAPI::P4RuntimeAnalyzer::addPkgInfo	(	const IR::ToplevelBlock *	evaluatedProgram,
		cstring	arch ) const

inline

Sets the pkg_info field of the P4Info message, using the annotations on the P4 program package.

void P4::ControlPlaneAPI::P4RuntimeAnalyzer::addValueSet ( const IR::P4ValueSet * inst )

inline

Look for a @match annotation on the struct field and set the match type of the match field appropriately.

static

Analyze a P4 program and generate a P4Runtime control plane API.

Parameters

program	The P4 program to analyze.
evaluatedProgram	An up-to-date evaluated version of the program.
refMap	An up-to-date reference map.
refMap	An up-to-date type map.
archHandler	An implementation of P4RuntimeArchHandlerIface which handles architecture-specific constructs (e.g. externs).
arch	The name of the P4_16 architecture the program was written against.

Returns: a P4Info message representing the program's control plane API. Never returns null.

void P4::ControlPlaneAPI::P4RuntimeAnalyzer::postAdd ( ) const

inline

To be called after all objects have been added to P4Info. Calls the architecture-specific postAdd method for post-processing.
