bool didChangeLayerOffsets

Must rebuild the layer offsets.

Definition at line 59 of file changes.h.

bool didChangeLayers

Must rebuild the layer tree. Implies didChangeLayerOffsets.

Definition at line 56 of file changes.h.

bool didChangeRelocates

Must rebuild the relocation tables.

Definition at line 62 of file changes.h.

bool didChangeSignificantly

A significant layer stack change means the composed opinions of the layer stack may have changed in arbitrary ways.

This represents a coarse invalidation. By way of contrast, an example of an insignificant change is adding or removing a layer empty of opinions.

Definition at line 69 of file changes.h.

SdfRelocatesMap newRelocatesTargetToSource

New relocation maps for this layer stack.

If didChangeRelocates is true, these fields will be populated as part of determining the changes to this layer stack. However, we do not immediately apply those changes to the layer stack; we store them here and commit them in Apply().

Definition at line 76 of file changes.h.

SdfPathSet pathsAffectedByRelocationChanges

Paths that are affected by the above relocation changes.

Definition at line 83 of file changes.h.
