Represents a set of options for aggregating tags.
Assembly: Microsoft.VisualStudio.Text.Logic (in Microsoft.VisualStudio.Text.Logic.dll)
Map only through projection buffers that have the "projection" content type. Normally, a tag aggregator maps up and down through all projection buffers (buffers that implement IProjectionBufferBase). This flag causes the projection buffer not to map through buffers that are projection buffers but do not have a projection content type. This is used by the classifier aggregator, because classification depends on content type.
Default behavior. The tag aggregator maps up and down through all projection buffers.
