pylal.metaarray.MetaArray

Class MetaArray

numpy.ndarray --+ | MetaArray

An array containing a data and metadata. Intended to be subclassed.

On b = MetaArray(a) where a is a MetaArray, metadata is copied, but data is not.

Nested Classes

[hide private]

_metadata_type
Abstract class to hold metadata

Instance Methods

[hide private]

__new__(subtype, data=None, metadata=None, dtype=None, copy=False, subok=True)

source code

__array_finalize__(self, obj)
Called anytime a MetaArray is returned; make sure that metadata is set to something.

source code

__array_wrap__(self, obj)
Called anytime a ufunc operates on a MetaArray and another object.

source code

__repr__(self)

source code

__str__(self)

source code

_get_data(self)

source code

__getstate__(self)
Returns the internal state of the object, for pickling purposes.

source code

__setstate__(self, state)
Restores the internal state of the masked array, for unpickling purposes.

source code

__reduce__(self)
Returns a 3-tuple for pickling a MetaArray

__array_wrap__(self, obj)

source code

Called anytime a ufunc operates on a MetaArray and another object. The result of the ufunc is obj. The MetaArray operand is self.

setstate(self, state)

source code

Restores the internal state of the masked array, for unpickling purposes. `state` is typically the output of the ``__getstate__`` output, and is a 5-tuple:

class name
a tuple giving the shape of the data
a typecode for the data
a binary string for the data
a binary string for the mask.

reduce(self)

source code

Returns a 3-tuple for pickling a MetaArray

reconstruction function
tuple to pass reconstruction function
state, which will be passed to __setstate__
