System. sysutils. tmarshaller and system. tmarshal

Tmarshaller (structure) is implemented based on tmarshal (a class composed of a lot of class methods.

Tcyclaller can manage the cache automatically (automatically released) and securely. tcyclal also has an important method that the former does not have, such as the tcyclal. Copy () method.

With them, it will be more convenient to perform operations such as memory buffers and string transcoding.

{Test} procedure tform1.formcreate (Sender: tobject); var M: tsf-aller; PW: tptrwrapper; STR: string; BS: tbytes; begin BS: = bytesof ('in case of Delphi blog'); PW: = m. allocmem (length (BS); tmarshal. copy (BS, 0, PW, length (BS); STR: = tmarshal. readstringasansi (PW); showmessage (STR); PW: = m. asutf8 (STR); STR: = tmarshal. readstringasutf8 (PW,-1); showmessage (STR); end;
