Member Function Documentation

◆ build()

bool P4::TC::IngressDeparserPNA::build ( )
overridevirtual

Reimplemented from P4::EBPF::EBPFDeparser.

◆ emit()

void P4::TC::IngressDeparserPNA::emit ( EBPF::CodeBuilder * builder)
overridevirtual

Reimplemented from P4::EBPF::EBPFDeparser.

◆ emitDeclaration()

void P4::TC::IngressDeparserPNA::emitDeclaration ( EBPF::CodeBuilder * builder,
const IR::Declaration * decl )
overridevirtual

Reimplemented from P4::EBPF::EBPFDeparserPSA.

◆ emitPreDeparser()

void P4::TC::IngressDeparserPNA::emitPreDeparser ( EBPF::CodeBuilder * builder)
overridevirtual

A "PreDeparser" is emitted just before a sequence of hdr.emit() functions. It is useful in the case of resubmit or clone operation, as these operations require to have an original packet.

Reimplemented from P4::EBPF::EBPFDeparser.
