ArrayAppendCache< T > Class Template Reference

#include <streamconversion_impl_helper.h>

Detailed Description

template<typename T>
class maxon::ArrayAppendCache< T >

Helper to Append efficiently to WritableArrayInterface<> by caching several append calls and writing them back in blocks Without this caching mechanism calling Append directly can slow down by a factor of 4 or even more! Usage:

FastArrayAppend<UChar> dst(xdst); // xdst is the WritableArrayInterface of type UChar
for (auto ch : src)
{
iferr (dst.Append(ch))
return err;
}
iferr (dst.Finalize()) // tell the FastArrayAppend that we are finished and remaning elements in the cache should be copied as well
return err;
Py_UCS4 ch
