class StepDumper from StepData
---Purpose : Provides a way to dump entities processed through STEP, with
-- these features :
-- - same form as for writing a STEP File (because it is clear
-- and compact enough, even if the names of the fields do not
-- appear) : thus, no additionnal resource is required
-- - possibility to look for an entity itself (only its Type or
-- with its content), an entity and it shared items (one level)
-- or all the entities its refers to, directly or recursively.
uses Messenger from Message, Transient, Protocol from StepData, StepModel,
GeneralLib, StepWriter, WriterLib
raises InterfaceMismatch
is
Create (amodel : StepModel; protocol : Protocol from StepData; mode : Integer = 0)
returns StepDumper;
---Purpose : Creates a StepDumper, able to work on a given StepModel
-- (which defines the total scope for dumping entities) and
-- a given Protocol from Step (which defines the authorized
-- types to be dumped)
-- <mode> commands what is to be displayed (number or label)
-- 0 for number (and corresponding labels are displayed apart)
-- 1 for label (and corresponding numbers are displayed apart)
-- 2 for label without anymore
StepWriter (me : in out) returns StepWriter is static;
---Purpose : Gives an access to the tool which is used to work : this allow
-- to acts on some parameters : Floating Format, Scopes ...
---C++ : return &
Dump (me : in out; S : Messenger from Message; ent : Transient; level : Integer)
returns Boolean
---Purpose : Dumps a Entity on an Messenger. Returns True if
-- sucess, False, if the entity to dump has not been recognized
-- by the Protocol. <level> can have one of these values :
-- - 0 : prints the TYPE only, as known in STEP Files (StepType)
-- If <ent> has not been regognized by the Protocol, or if its
-- type is Complex, the StepType is replaced by the display of
-- the cdl type. Complex Type are well processed by level 1.
-- - 1 : dumps the entity, completely (whatever it has simple or
-- complex type) but alone.
-- - 2 : dumps the entity completely, plus the item its refers to
-- at first level (a header message designates the starting
-- entity of the dump) <Lists Shared and Implied>
-- - 3 : dumps the entity and its refered items at any levels
--
-- For levels 1,2,3, the numbers displayed (form #nnn) are the
-- numbers of the corresponding entities in the Model
raises InterfaceMismatch;
-- Errors come from StepWriter, they especially occur when an
-- entity does not come from the starting Model.
-- Level 0 accepts an entity which does not come from the Model.
Dump (me : in out; S : Messenger from Message; num : Integer; level : Integer)
returns Boolean
---Purpose : Works as Dump with a Transient, but directly takes the
-- entity designated by its number in the Model
-- Returns False, also if <num> is out of range
raises InterfaceMismatch;
-- Errors : same as above
