Public Static Functions
create
Public factory method from istream.
The Resource object will take memory ownership of the istream. Zorba will pass it to aStreamReleaser when it is no longer needed, so that the original client may delete it.
Parameters
| aStream |
An istream whence to read the string's content. |
| aStreamReleaser |
A function pointer which is invoked once the StreamResource is destroyed. Normally this function will delete the std::istream object passed to it. |
Public Functions
destroy
Destroy/clean up this Resource.
Zorba will call this method when it no longer needs the Resource. It is the responsibility of subclasses to clean up appropriate when this method is called, including calling "delete this" if the Resource was allocated with "new".
