Class: CTemplate
Synopsis: A Denali compiled template.
NOTE: CTemplate's primary client is CTemplateCacheManager, which maintains
a cache of compiled templates.
USAGE
-----
The CTemplate class must be used as follows:
CLASS INIT - InitClass must be called before any CTemplate can be created.
NEW TEMPLATE - For each new template the client wants to create, the client
must do the following, in order:
1) New a CTemplate
2) Initialize the CTemplate by calling Init, passing a source file name
3) Load the CTemplate by calling Load; when Load returns, the new CTemplate is ready for use.
EXISTING TEMPLATE - To use an existing template, the client must:
1) Call Deliver; when Deliver returns, the existing CTemplate is ready for use.
CLASS UNINIT - UnInitClass must be called after the last CTemplate has been destroyed.
To ensure thread-safety, the client must implement a critical section
around the call to Init. Init is designed to be as fast as possible,
so the client can quickly learn that it has a pending template for a given
source file, and queue up other requests for the same source file.
CTemplate provides implementations for Debug documents, namely
IDebugDocumentProvider & IDebugDocumentText
