Detailed Description

template<typename T>
struct P4::StructTypeReplacement< T >

Describes how a nested struct type is replaced: the new type to replace it and how each field is renamed. For example, consider the following:

struct S { bit a; bool b; }

struct T { S s; bit<6> y; }

struct M { T t; bit<3> x; }

Member Function Documentation

dbprint()

template<typename T >

virtual void P4::StructTypeReplacement< T >::dbprint ( std::ostream & out ) const

inlinevirtual

Implements P4::IHasDbPrint.

explode()

template<typename T >

const IR::StructExpression * P4::StructTypeReplacement< T >::explode ( const IR::Expression * root, cstring prefix )

inline

Returns a StructExpression suitable for initializing a struct for the fields that start with the given prefix. For example, for prefix .t and root R this returns { .s = { .a = R._t_s_a0, .b = R._t_s_b1 }, .y = R._t_y2 }
