Detailed Description

This file defines a series of test objects which, in sum, produce an abstract test specification. This test specification is reified into a concrete test specification by the individual test back ends of a target extension.

Member Function Documentation

evaluate()

const Packet * P4::P4Tools::P4Testgen::Packet::evaluate ( const Model & model, bool doComplete ) const

nodiscardoverridevirtual

Returns

a version of the test object where all expressions are resolved and symbolic variables are substituted according to the mapping present in the

Parameters

model.

Implements P4::P4Tools::P4Testgen::TestObject.

getEvaluatedPayload()

const IR::Constant * P4::P4Tools::P4Testgen::Packet::getEvaluatedPayload ( ) const

nodiscard

Returns

the payload of the packet, which, at this point, needs to be a constant. A BUG is thrown otherwise.

getEvaluatedPayloadMask()

const IR::Constant * P4::P4Tools::P4Testgen::Packet::getEvaluatedPayloadMask ( ) const

nodiscard

Returns

the don't care mask of the packet, which, at this point, needs to be a constant. If a bit is set in the @payloadIgnoreMask, the corresponding bit in @payload is ignored. A BUG is thrown otherwise.

getObjectName()

cstring P4::P4Tools::P4Testgen::Packet::getObjectName ( ) const

nodiscardoverridevirtual

Returns

the string name of this particular test object.

Implements P4::P4Tools::P4Testgen::TestObject.

getPort()

int P4::P4Tools::P4Testgen::Packet::getPort ( ) const

nodiscard

Returns

the port that is associated with this packet.
