Module `Vlt.Paje`Source

This module provides support for the Pajé tool (version 1.2.3).

Pajé (available at http://paje.sourceforge.net) is a graphical tool for the analysis of multithreads and/or multiprocesses programs.

Bolt can produce Pajé-compatible traces by using statements like:

LOG Paje.t WITH Paje.new_event ...;

more information can be found in the Bolt manual.

Definitions

Sourceval t : string

The identifier message for Pajé event.

Sourcetype properties = (string * string) list

The type of information to be recorded in a trace.

Sourcetype name = string

Synonym for names.

Sourcetype alias = string

Synonym for aliases.

Sourcetype color = float * float * float

The type of colors, as three red/green/blue components (each should be between 0.0 and 1.0).

Predefined events: trace recording

Source

val create_container : 
  name:name ->
  typ:string ->
  ?container:name ->
  ?alias:alias ->
  properties ->
  properties

Creates a container with name, type, optional parent container, optional alias and a list of additional properties.

Sourceval destroy_container : name:name -> typ:string -> properties -> properties

Destroys a container with name, type, and a list of additional properties.

Source

val set_state : 
  typ:string ->
  container:name ->
  value:string ->
  properties ->
  properties

Changes the state of a given container to a new value with passed type, and additional list of properties.

Source

val push_state : 
  typ:string ->
  container:name ->
  value:string ->
  properties ->
  properties

Pushes the current state of a given container to its own stack, and changes its state to the passed type and value.

Sourceval pop_state : typ:string -> container:name -> properties -> properties

Changes the states of a given container by poping a previously pushed value from its own stack.

Sourceval reset_state : typ:string -> container:name -> properties -> properties

Clears all previously saved values for the type of a container.

Source

val new_event : 
  typ:string ->
  container:name ->
  value:string ->
  properties ->
  properties

Records a new event with type, container, value, and additional list of properties.

Source

val set_variable : 
  typ:string ->
  container:name ->
  value:float ->
  properties ->
  properties

Sets the value of a container variable.

Source

val add_variable : 
  typ:string ->
  container:name ->
  value:float ->
  properties ->
  properties

Increases the value of a container variable by a given amount.

Source

val sub_variable : 
  typ:string ->
  container:name ->
  value:float ->
  properties ->
  properties

Decreases the value of a container variable by a given amount.

Source

val start_link : 
  typ:string ->
  container:name ->
  start_container:name ->
  value:string ->
  key:string ->
  properties ->
  properties

Records the start of a link occuring inside a container, from a start. The key/value pair is used to match with an associated end of link.

Source

val end_link : 
  typ:string ->
  container:name ->
  end_container:name ->
  value:string ->
  key:string ->
  properties ->
  properties

Records the end of a link occuring inside a container, to an end. The key/value pair is used to match with an associated start of link.

Layout elements

Sourceval header : string list

The header defining Pajé events.

Sourceval render : Event.t -> string

The rendering function for Pajé format.

Sourceval layout : Layout.t

The layout supporting the "Pajé" trace format. The message of the event should match the name of an EventDef defined by the "Pajé trace file format" available at http://paje.sourceforge.net/download/publication/lang-paje.pdf. The values of the fields are taken from the event properties, the "Time" field being automatically set to the time elapsed since program start (unless explicitly set through a property).

Sourceval layout_noheader : Layout.t

Functorial interface

Sourcetype type_kind =

| Container
| State
| Event
| Variable
| Link
| Entity_value

Sourceexception Invalid_type of type_kind

Sourcemodule type Definitions = sig ... end

The input signature of Paje.Make, that is static definition of Pajé types.

Sourcemodule type S = sig ... end

The output signature of Paje.Make, that is type-safe interface to Pajé functions.

Source

module Make
  (D : Definitions) : 
  S
    with type container_type = D.container_type
     and type event_type = D.event_type
     and type state_type = D.state_type
     and type variable_type = D.variable_type
     and type link_type = D.link_type

Functor building a type-safe version of Pajé trace-recording functions. Definitions from the passed module are recorded at the "TRACE" level.
