class, default_dtype=<class 'numpy.float64'>)[source]

Read in fields for first node in all trees/forest.

This function is optimized for the struct of arrays layout. It will work for array of structs layout, but field access will be 1 to 2 orders of magnitude slower.

__init__(arbor, default_dtype=<class 'numpy.float64'>)

Initialize self. See help(type(self)) for accurate signature.


__init__(arbor[, default_dtype]) Initialize self.
get_fields(data_object[, fields]) Load field data for a data object into storage structures.
