OMNI_GRAPH_EXEC_SET_NODE_DATA

OMNI_GRAPH_EXEC_SET_NODE_DATA(context_, type_, ...)

Calls either omni::graph::exec::unstable::IExecutionContext::setNodeData() or omni::graph::exec::unstable::IExecutionStateInfo::setNodeData() (dependent on the type of the first argument).

The purpose of this macro is to generate an appropriate omni::core::TypeId at compile time from the data item’s type. The user can manually do this, but this macro is much less error prone.

OMNI_GRAPH_EXEC_SET_NODE_DATA(
    stateInfo,                      // pointer to either IExecutionContext or IExecutionStateInfo
    GraphContextCacheOverride,      // type of the data to store
    tokens::kInstanceContext,       // key to store the data at in the node's key/value datastore
    std::move(contextOverridePtr)   // pointer to the data to store
);

The macro itself is a variadic macro and can map to multiple overloads of setNodeData() methods in the interface given as the first argument

Returns a pointer to the given data.

With newer compilers (GCC >= 8), this macro can be replaced with templated methods (without breaking the ABI).
