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
#include
main(){
RWFileManager fm("filename.dat");
// Initializes filename.dat with an empty root:
RWBTreeOnDisk bt(fm);
}
