Examples of org.teiid.query.util.CommandContext

org.teiid.query.util.CommandContext
Defines the context that a command is processing in. For example, this defines who is processing the command and why. Also, this class (or subclasses) provide a means to pass context-specific information between users of the query processor framework.
