is_directory_format

function of dascore.io.core

source

is_directory_format(
    path ,
)-> ‘bool’

Return True if a directory is itself one FiberIO scan unit.

A directory-format source (e.g. XMLBinary) is read as a whole rather than by traversing its members. This is the single definition of that condition; dc.scan’s traversal skips such a directory’s contents and the directory indexer treats it as one stat unit.
