Construction
An
RWBTreeOnDisk is always constructed from an
RWFileManager. If the
RWFileManager is managing a new file, then the
RWBTreeOnDisk will initialize it with an empty root node. For example, the following code fragment constructs an
RWFileManager for a new file called
filename.dat and then constructs an
RWBTreeOnDisk from it:
#include <rw/disktree.h>
#include <rw/filemgr.h>
int main(){
RWFileManager fm("filename.dat");
// Initializes filename.dat with an empty root:
RWBTreeOnDisk bt(fm);
}
