Class TestString Undocumented
Class TestStructuredDtypeSparseFields Tests subarray fields which contain sparse dtypes so that not all memory is used by the dtype work. Such dtype's should leave the underlying memory unchanged.
Class TestStructuredObjectRefcounting These tests cover various uses of complicated structured types which include objects and thus require reference counting.

def iter_struct_object_dtypes(): (source)

Iterates over a few complex dtypes and object pattern which fill the array with a given object (defaults to a singleton).

Yields
  • dtype: dtype
  • pattern: tuple - Structured tuple for use with np.array.
  • count: int - Number of objects stored in the dtype.
  • singleton: object - A singleton object. The returned pattern is constructed so that all objects inside the datatype are set to the singleton.
