◆ build()

PathElementHandler lsst.obs.base.gen2to3.repoWalker.builders.BuilderNode.build (   self,
PathElementParser  parser,
Dict[str, type]  allKeys,
Dict[str, type]  cumulativeKeys,
*Optional[re.Pattern]  fileIgnoreRegEx,
Optional[re.Pattern]   dirIgnoreRegEx 
)
Transform this node in the build tree into a corresponding
`PathElementHandler`, recursing to any children.

Must be called after `prune`.

Parameters
----------
parser : `PathElementParser`
    An object that matches the path element the new handler is
    responsible for and extracts a (partial) Gen2 data ID from it.
allKeys : `dict` [`str`, `type`]
    A mapping from Gen2 data ID key to the type of its value.  Will
    contain all keys that may be extracted by the given parser, and
    possibly others.
cumulativeKeys : `dict` [`str`, `type`], optional
    A dictionary containing key strings and types for Gen2 data ID keys
    that have been extracted from previous path elements for this
    template, including those extracted by ``parser``.

Returns
-------
handler : `PathElementHandler`
    A new handler object.

◆ prune()

Tuple[BuilderNode, List[str], bool] lsst.obs.base.gen2to3.repoWalker.builders.BuilderNode.prune (   self)
Attempt to prune this node and its children from the tree.

Returns
-------
replacement : `BuilderNode`
    The result of recursively pruning child nodes; often just ``self``.
messages : `list` [`str`]
    Warning messages that should be logged by a parent node when a
    matching path element is encountered, if this node is pruned.
prune : `bool`
    If `True`, this node may be pruned from the tree (but will not
    necessarily be - it may correspond to a path element that should
    be skipped with siblings that should not be).

Reimplemented in lsst.obs.base.gen2to3.repoWalker.builders.BuilderTree, lsst.obs.base.gen2to3.repoWalker.builders.BuilderDuplicateInputs, lsst.obs.base.gen2to3.repoWalker.builders.BuilderPrunedTree, lsst.obs.base.gen2to3.repoWalker.builders.BuilderTargetInput, and lsst.obs.base.gen2to3.repoWalker.builders.BuilderSkipInput.
