Examples of org.mozilla.javascript.Context

org.mozilla.javascript.Context
This class represents the runtime context of an executing script. Before executing a script, an instance of Context must be created and associated with the thread that will be executing the script. The Context will be used to store information about the executing of the script such as the call stack. Contexts are associated with the current thread using the {@link #call(ContextAction)}or {@link #enter()} methods.
Different forms of script execution are supported. Scripts may be evaluated from the source directly, or first compiled and then later executed. Interactive execution is also supported.
Some aspects of script execution, such as type conversions and object creation, may be accessed directly through methods of Context. @see Scriptable @author Norris Boyd @author Brendan Eich
