The method IComponentStreaming.Process has two parameters, input and output, that represent the InputStream and OutputStream types, respectively. The abstract base class StreamingComponentBase implements the IComponentStreaming interface. Any implementation of IComponentStreaming only needs to subclass the StreamingComponentBase class. Defined earlier in the section Architecting the Television Selection System were three different IComponent implementation types: input sink, output sink, and filter. A further optimization is to define input sink and output sink abstract base classes that subclass StreamingComponentBase as follows: public abstract class InputSink<type> : StreamingComponentBase< type> where type : new() { public abstract void Process( OutputStream<type> output ); public virtual void Process( InputStream<type> input, OutputStream<type> output ) { foreach( type item in input ) { output.Write( item ); } Process( output ); } } public abstract class OutputSink<type> : StreamingComponentBase<type> where type: new() { public abstract void Process( InputStream<type> input ); public virtual void Process( InputStream<type> input, OutputStream<type> output ) { Process( input ); } } InputSink and OutputSink are defined as Generic types and as abstract classes that derive from the StreamingComponentBase type. Abstract classes are used because both InputSink and OutputSink are helper classes that shouldn t be instantiated on their own. Each class implements the Process method with the input, output parameter signature. In the case of InputSink, the Process implementation copies the input stream to the output stream. Having copied all elements, a modified Process method is called that only passes in the OutputStream parameter. OutputSink doesn t copy any data and exposes a Process method with only the InputStream parameter.

GtkTreeViewColumn headers provide more functionality beyond column titles for some tree views. In sortable tree models, clicking the column header can initiate sorting of all of the rows according to the data held in the corresponding column. It also gives a visual indication of the sort order of the column if applicable. You should not hide the headers if the user will need them to sort the tree view rows. Another GtkTreeView function, gtk_tree_view_set_rules_hint() requests a GTK+ theme to differentiate between alternating rows. This is often done by changing the background color of adjacent rows. However, as the function name suggests, this property is only a hint for the theme engine and may not be honored. Also, some theme engines alternate background colors automatically regardless of this setting. void gtk_tree_view_set_rules_hint (GtkTreeView *treeview, gboolean alternate_colors); This property should only be used if it is a necessity. For example, if your tree view contains many rows, it could help the user navigate throughout its contents. In contrast, it should not be used for aesthetic purposes, because those settings should always be dictated by the user s theme. As a GTK+ developer, you should be very careful about changing visual properties. Users have the ability to choose themes that fit their needs, and you can make your application unusable by changing how widgets are displayed.

You might guess from what I ve just said about the destructor suppressing the finalizer that the finalizer doesn t get called directly for objects created with stack semantics. When objects with stack semantics are destroyed at the end of a function scope, the destructor is called, but not the finalizer. Code that frees the resources should be written in the finalizer, and the destructor should call the finalizer. That way, you know your cleanup will be called regardless of whether the destructor is called or not. If it is called, the cleanup executes because the destructor calls the finalizer, and the finalizer cleans up. If it is not called, the finalizer eventually is called by the garbage collector or application shutdown process, that is, when the application domain (the CLR term for the entire space that all the application s names exist in) shuts down. In Listing 6-18, one file is opened using a native file handle, an unmanaged resource. Another file is opened using the StreamWriter class. Listing 6-18. Handling Managed and Unmanaged Resources // file_converter.cpp #include <stdio.h> #include <string.h> #include <stdlib.h> #include <vcclr.h> // for PtrToStringChars
