Detailed Description

Proxy environment buffer.

The first 64 bytes of the environment structure are a scratch area. The Root proxies put a collection iterator there, but we instead lay it out like this.

This is slightly different in newer versions of root. Rather than having the 64-byte buffer, Environ takes a template argument giving the payload.

◆ fCont

Cont_t* xAOD::TDVCollectionFuncs::TEnvBuff::fCont

Pointer to the container.

(Note that the object pointer from the environment will point at the top-level DataVector class; this points directly at the vector.)

◆ fEltPtr

void* xAOD::TDVCollectionFuncs::TEnvBuff::fEltPtr

The last element pointer to have been returned.

Definition at line 184 of file TDVCollectionProxy.cxx.

◆ fIndex

size_t xAOD::TDVCollectionFuncs::TEnvBuff::fIndex

The index of the last element retrieved.
