Detailed Description

Codes for interfacing with numpy arrays.

Function Documentation

append()

TECA_EXPORT bool teca_py_array::append	(	teca_variant_array *	varr,
		PyObject *	obj
	)

Append values from the object to the variant array.

copy()

TECA_EXPORT bool teca_py_array::copy	(	teca_variant_array *	varr,
		PyObject *	obj
	)

Copy values from the object into variant array.

new_object() [1/2]

TECA_EXPORT PyArrayObject* teca_py_array::new_object	(	teca_variant_array *	varr,
		bool	deep_copy = false
	)

Construct a new numpy array initialized with the contents of the variant array.

new_object() [2/2]

template<typename NT >

TECA_EXPORT PyArrayObject* teca_py_array::new_object	(	teca_variant_array_impl< NT > *	varrt,
		bool	deep_copy = false
	)

Construct a new numpy array initialized with the contents of the variant array.

new_variant_array()

TECA_EXPORT p_teca_variant_array teca_py_array::new_variant_array	(	PyObject *	obj,
		bool	deep_copy = false
	)

Construct a new variant array and initialize it from the object. The data is transferred by zero-copy operation if possible and if not then a deep copy is made. One can force a deep copy. Returns a new variant array if successful and a nullptr otherwise.

set()

TECA_EXPORT bool teca_py_array::set	(	teca_variant_array *	varr,
		unsigned long	i,
		PyObject *	obj
	)

Set i'th element of the variant array to the value of the object.

variant_array_capsule_destrcutor()

template<typename NT >

void teca_py_array::variant_array_capsule_destrcutor

(

PyObject *

cap

)

a destructor used with the following funciton
