Member Function Documentation

emitHeaderInstances()

void P4::EBPF::EBPFProgram::emitHeaderInstances ( CodeBuilder * builder )

protectedvirtual

Reimplemented in P4::EBPF::EBPFPipeline.

emitLocalVariables()

void P4::EBPF::EBPFProgram::emitLocalVariables ( CodeBuilder * builder )

protectedvirtual

Reimplemented in P4::EBPF::EBPFPipeline, and P4::TC::TCIngressPipelinePNA.

isLibraryMethod()

bool P4::EBPF::EBPFProgram::isLibraryMethod ( cstring methodName )

protectedvirtual

Checks whether a method name is considered to be part of the standard library, e.g., defined in core.p4 or ebpf_model.p4. TODO: Should we also distinguish overloaded methods?

Reimplemented in P4::UBPF::UBPFProgram.
