Detailed Description

Function Documentation

Composite_Exercise()

void Composite_Exercise

(

void

)

Example of using the Composite Pattern.

The Composite pattern is used when a collection of objects is to be formed in a hierarchical form where each object needs to be treated like any other object but some objects can contain other objects.

This example uses a file structure of file and directories to represent each object type.

Composite_Exercise_FormatEntry()

static void Composite_Exercise_FormatEntry ( FileDirEntry *  entry, int  depth, DynamicString *  output  )

static

Format the specified entry for display.

This is a recursive call.

Parameters
