Property Documentation

Children

override FileDirEntry [] Children

get

Retrieve the children of this node.

This is an override of the base class and uses a collection of children entries stored in the DirEntry class so the base class doesn't need to store it.

Definition at line 192 of file Composite_FileDirEntry.cs.

Length

override long Length

get

Retrieve the size of all children of this directory. The length is calculated on the first call and cached for subsequent calls.

This is an override of the base class to provide different behavior.
