Detailed Description

Bitquad scalar computer backed by finite-window computation.

This class obtains bitquad family increments from its finite-window computation, aggregates them into per-node family counts, and materializes the public BITQUAD_* descriptors. The public attribute pipeline/topology backend invokes this computer for bitquad requests.

The computer exposes the standard scalar bitquad descriptors. For component trees, connectivity comes from the tree's adjacency relation. For a tree of shapes whose lower- and upper-shape connectivity differ, scalar projection derives each non-root shape's polarity from its exact node altitude and its parent's altitude. The root has no shape polarity and is handled explicitly by the projection policy.

Member Function Documentation

compute() [1/2]

template<std::floating_point Real, AltitudeValue T>

static void mmcfilters::attributes::computers::BitquadAttributeComputer::compute ( const AltitudeAttributeComputeContext< Real, T > &  context )

inlinestatic

Computes requested bitquad attributes using a generic altitude span.

This overload exists for valued-tree callers with a generic exact altitude type. Component-tree inputs still derive scalar connectivity from the tree adjacency relation.

Parameters

context

Operation context or diagnostic label.

Definition at line 120 of file BitquadAttributeComputer.hpp.

compute() [2/2]

template<std::floating_point Real>

static void mmcfilters::attributes::computers::BitquadAttributeComputer::compute ( const AttributeComputeContext< Real > &  context )

inlinestatic

Computes requested scalar bitquad attributes for every live node.

This entry point first computes family increments, aggregates them into final per-node family counts, and then projects only the requested scalar descriptors into the caller-provided flat buffer. Rows are dense internal node ids interpreted by context.attrNames. This topology-only overload is valid for component trees with a regular adjacency relation.

Parameters

context

Operation context or diagnostic label.

Definition at line 98 of file BitquadAttributeComputer.hpp.

computeUnitRows()

template<std::floating_point Real>

static void mmcfilters::attributes::computers::BitquadAttributeComputer::computeUnitRows ( const UnitAttributeComputeContext< Real > &  context )

inlinestatic

Materializes bitquad attributes for unit proper-part supports.

The unit path defines the scalar bitquad constants for one-pixel supports. It is used by the attribute pipeline when values must be supplied for unit leaves outside the internal tree-node accumulation path.

Unit constants depend on the tree adjacency relation. The method rejects trees without regular adjacency metadata.

Parameters

context

Operation context or diagnostic label.
