Detailed Description

template<typename Kind>
struct P4::ControlPlaneAPI::Helpers::Counterlike< Kind >

The information about a counter or meter instance which is necessary to serialize it. @Kind must be a class with a CounterlikeTraits<> specialization. This can be useful for different architectures as many define extern types for counter / meter. The architecture-specific code must specialize CounterlikeTraits<> appropriately.

from()

template<typename Kind >

static std::optional< Counterlike< Kind > > P4::ControlPlaneAPI::Helpers::Counterlike< Kind >::from ( const IR::ExternBlock * instance, const ReferenceMap * refMap, P4::TypeMap * typeMap, ::p4::config::v1::P4TypeInfo * p4RtTypeInfo )

inlinestatic

Returns

the information required to serialize an explicit @instance of @Kind, which is defined inside a control block.

fromDirect()

template<typename Kind >

static std::optional< Counterlike< Kind > > P4::ControlPlaneAPI::Helpers::Counterlike< Kind >::fromDirect ( const ExternInstance & instance, const IR::P4Table * table )

inlinestatic

Returns

the information required to serialize an @instance of @Kind which is either defined in or referenced by a property value of @table. (This implies that @instance is a direct resource of @table.)

index_type_name

template<typename Kind >

const cstring P4::ControlPlaneAPI::Helpers::Counterlike< Kind >::index_type_name

If the type of the index is a user-defined type, this is the name of the type. Otherwise it is nullptr.
