	resizes the data: if newnmax==0, dereferences the old array if newnmax<=nmax, keeps the old one if newnmax>nmax dereferences the old array, allocates new, changes to master mode

pencil &	copy_data (const pencil &other, int mode=0)
	copies data from other pencil mode=0: if this size is too small, creates new reference data! in which case other referring pencils will not be updated mode=1: if this size is too small, copies the first portion of the data only

Detailed Description

template<class T, class container_t = ptr_container<T>>
class pencil< T, container_t >

class for controlling one-dimensional data arrays of type T the array can be managed and copied by reference (ref counting used) compatible with vector<T> used as container

Constructor & Destructor Documentation

pencil()

template<class T , class container_t = ptr_container<T>>

pencil< T, container_t >::pencil ( container_arg< container_t >  arg, int  snmax, int  sn = 0, int  managed = 0  )

inline

Constructor form existing container.

Container pointer is to be used as the first argument, f.e. T* in case of pointer container or vector<T> * in case of vector container Container_arg makes the proper argument conversion if managed=0 will not delete ptr, 1-deletes, 2-makes a copy of sn elements and does not remember ptr
