virtual Int_t ADF::NarvalFilter::AttachOutput ( FrameBlock *  block,
Int_t  slot = -1 
)
inlinevirtual

Attach a block as output for a given slot number.

slot < 0 means attach it on the top of the stack in case the actor can handle many output. As a consequence, GetNbOutput is increased by 1. The returned value is the slot position if slot < 0 and >= GetNbOutput, the block cannot be attached and it returns -1

Reimplemented from ADF::NarvalInterface.
