Detailed Description

template<typename T>
class PySequenceHolder< T >

Class to hold sequences (lists, tuples, arrays, etc.) passed from Python -> C++.

PySequenceHolder is templated on the type of the contained object.

The class is lazy: elements are not evaluated until requested within the C++ code.

Member Function Documentation

operator[]()

template<typename T>

T PySequenceHolder< T >::operator[] ( unsigned int which ) const

inline

Returns an element of the sequence.

ARGUMENTS:

• which: an integer specifying which element should be returned.

NOTES:

• if the sequence is not which elements long, we raise an IndexError
• if the element cannot be converted to type T, we raise a ValueError

size()

template<typename T>

unsigned int PySequenceHolder< T >::size ( ) const

inline

Returns the size of the contained sequence.

NOTE: the sequence must have a __len__ attribute, otherwise a ValueError will be raised.
