INVLIB::InvBeamformer stores the spatial filter weights produced by InvLCMV::makeLCMV or InvDICS::makeDICS together with the whitener, SSP projector, source-space vertex list, source normals, weight-normalisation mode (none / unit-noise-gain / NAI), max-power orientations and (for DICS) the per-frequency filter stack. Holding all this on one value lets the apply* members re-project new data or covariances through a fixed set of filters without rebuilding any of the heavy quantities, mirroring MNE-Python's Beamformer dict.
