/*
* CodeGeneratorInstrumentation.py uses this file as a source to generate
* InspectorInstrumentationInl.h and InspectorInstrumentationImpl.cpp
*
* The code below is not a correct IDL but a mix of IDL and C++.
*
* The syntax for an instrumentation method is as follows:
*
*    [methodAttributes] returnValue methodName([paramAttr1] param1, [paramAttr2] param2, ...)
*
* Where:
*   methodAttributes - optional list of method attributes.
*       Attributes containing "=" are code generation options:
*           Inline=Custom - do not generate the public inline method.
*           Inline=FastReturn - return early from the inline method if there are no frontends.
*           Inline=Forward - generate a simple forwarding inline method that does not
                             modify the parameter list (implies Inline=FastReturn)
*       Attributes without "=" are the names of the agents to be invoked.
*           Examples: DOM, Page, Debugger.
*
*   paramAttr - optional attribute controlling the parameters handling (one attribute per parameter max).
*       Keep - pass first parameter (used to access the InstrumentingAgents instance) to agents.
*       FastReturn - return early from the inline method if this parameter is 0/false.
*
*   returnValue: C++ return value. Only "void" and "InspectorInstrumentationCookie" are supported.
*
*   methodName: C++ name for the public instrumentation method and agents methods.
*
*   paramList: C++ parameter list with optional names. Names will be deduced from types if omitted but you have to
*        specify explicit names for multiple parameters of the same type.
