Member Function Documentation

const handle& dec_ref ( ) const

inlineinherited

\rst
Manually decrease the reference count of the Python object. Usually, it is
preferable to use the `object` class which derives from `handle` and calls
this function automatically. Returns a reference to itself.

Definition at line 199 of file pytypes.h.

const handle& inc_ref ( ) const

inlineinherited

\rst
Manually increase the reference count of the Python object. Usually, it is
preferable to use the `object` class which derives from `handle` and calls
this function automatically. Returns a reference to itself.

Definition at line 192 of file pytypes.h.

operator bool ( ) const

inlineexplicitinherited

Return true when the handle wraps a valid Python object.

Definition at line 207 of file pytypes.h.

bool operator== ( const handle &  h ) const

inlineinherited

\rst
Deprecated: Check that the underlying pointers are the same.
Equivalent to ``obj1 is obj2`` in Python.

Definition at line 213 of file pytypes.h.

PyObject* ptr ( ) const

inlineinherited

Return the underlying PyObject * pointer.

Definition at line 184 of file pytypes.h.

static PyObject* raw_array ( PyObject *  ptr, int  ExtraFlags = 0  )

inlinestaticinherited

Create array from any object – always returns a new reference.

Definition at line 825 of file numpy.h.

handle release ( )

inlineinherited

\rst
Resets the internal pointer to ``nullptr`` without decreasing the
object's reference count. The function returns a raw handle to the original
Python object.

Definition at line 249 of file pytypes.h.
