pyarrow.UnionType

class pyarrow.UnionType

Bases: pyarrow.lib.DataType

Base class for union data types.

__init__(*args, **kwargs)

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

Methods

__init__(*args, **kwargs)	Initialize self.
equals(self, other)	Return true if type is equivalent to passed value.
to_pandas_dtype(self)	Return the equivalent NumPy / Pandas dtype.

Attributes

bit_width
id
mode	The mode of the union (“dense” or “sparse”).
num_buffers	Number of data buffers required to construct Array type excluding children.
num_children	The number of child fields.
num_fields	The number of child fields.
type_codes	The type code to indicate each data type in this union.
