IGESData

Prepares General dynamic data used for IGESData specifically : Protocol and Modules, which treat UndefinedEntity.

Returns a Protocol from IGESData (avoids to create it).

From the name of unit, computes flag number, 0 if incorrect (in this case, user defined entity remains possible).

From the flag of unit, determines value in MM, 0 if incorrect.

From the flag of unit, determines its name, "" if incorrect.

From the flag of IGES version, returns name, "" if incorrect.

Returns the maximum allowed value for IGESVersion Flag.

From the flag of drafting standard, returns name, "" if incorrect.

Returns the maximum allowed value for Drafting Flag.

Returns Flag corresponding to the scaling theValue. Returns 0 if there's no such flag.

Returns the designated model.

Sets a new unit from its flag (param 14 of Global Section) Returns True if done, False if <flag> is incorrect.

Sets a new unit from its value in meters (rounded to the closest one, max gap 1%) Returns True if done, False if <val> is too far from a suitable value.

Sets a new unit from its name (param 15 of Global Section) Returns True if done, False if <name> is incorrect Remark : if <flag> has been set to 3 (user defined), <name> is then free.

Applies unit value to convert header data : Resolution, MaxCoord, MaxLineWeight Applies unit only once after SetUnit... has been called, if <enforce> is given as True. It can be called just before writing the model to a file, i.e. when definitive values are finally known.

Performs the re-computation of status on the whole model (Subordinate Status and Use Flag of each IGES Entity), which can have required values according the way they are referenced (see definitions of Logical use, Physical use, etc...).

Performs auto-correction on an IGESEntity Returns True if something has changed, False if nothing done.
Works with the specific IGES Services : DirChecker which allows to correct data in "Directory Part" of Entities (such as required values for status, or references to be null), and the specific IGES service OwnCorrect, which is specialised for each type of entity.

Performs auto-correction on the whole Model Returns the count of modified entities.

Creates a DefaultGeneral and puts it into GeneralLib, bound with a Protocol from IGESData.

Returns a DirChecker, specific for each type of Entity Here, Returns an empty DirChecker (no constraint to check).

Creates a DefaultSpecific and puts it into SpecificLib.

creates a DefSwitch as Void

sets DefSwitch to "Void" status (in file : Integer = 0)

sets DefSwitch to "Reference" Status (in file : Integer < 0)

sets DefSwitch to "Rank" with a Value (in file : Integer > 0)

returns DefType status (Void,Reference,Rank)

returns Value as Integer (sensefull for a Rank)

Returns True if at least one criterium has already been set Allows user to store a DirChecker (static variable) then ask if it has been set before setting it.

Sets a DirChecker with most current criteria, that is : Structure Ignored ( worths call Structure(crit = DefVoid) ).

Sets Structure criterium. If crit is DefVoid, Ignored : should not be defined If crit is DefReference, Required : must be defined Other values are not taken in account.

Sets LineFont criterium If crit is DefVoid, Ignored : should not be defined If crit is DefAny, Required : must be defined (value or ref) If crit is DefValue, Required as a Value (error if Reference) Other values are not taken in account.

Sets LineWeight criterium If crit is DefVoid, Ignored : should not be defined If crit is DefValue, Required Other values are not taken in account.

Sets Color criterium If crit is DefVoid, Ignored : should not be defined If crit is DefAny, Required : must be defined (value or ref) Other values are not taken in account.

Sets Graphics data (LineFont, LineWeight, Color, Level, View) to be ignored according value of Hierarchy status : If hierarchy is not given, they are Ignored any way (that is, they should not be defined) If hierarchy is given, Graphics are Ignored if the Hierarchy status has the value given in argument "hierarchy".

Sets Blank Status to be ignored (should not be defined, or its value should be 0).

Sets Blank Status to be required at a given value.

Sets Subordinate Status to be ignored (should not be defined, or its value should be 0).

Sets Hierarchy Status to be ignored (should not be defined, or its value should be 0).

Sets Hierarchy Status to be required at a given value.

Performs the Checks on an IGESEntity, according to the recorded criteria In addition, does minimal Checks, such as admitted range for Status, or presence of Error status in some data (Color, ...).

Performs a Check only on Values of Type Number and Form Number This allows to do a check on an Entity not yet completely filled but of which Type and Form Number have been already set.

Corrects the Directory Entry of an IGES Entity as far as it is possible according recorded criteria without any ambiguity :

• if a numeric Status is required a given value, this value is enforced
• if an item is required to be Void, or if it recorded as Erroneous, it is cleared (set to Void)
• Type Number is enforced
• finally Form Number is enforced only if one and only Value is admitted (no range, see Constructors of DirChecker)

Returns result of last recognition (call of Evaluate).

Adds a new Recognizer to the Compound, at the end Several calls to Add work by adding in the order of calls : Hence, when Eval has failed to recognize, Evaluate will call Evaluate from the first added Recognizer if there is one, and to the second if there is still no result, and so on.

Semantic Checking of an IGESEntity. Performs general Checks, which use DirChecker, then call OwnCheck which does a check specific for each type of Entity.

Returns a DirChecker, specific for each type of Entity (identified by its Case Number) : this DirChecker defines constraints which must be respected by the DirectoryPart.

Performs Specific Semantic Check for each type of Entity.

Specific answer to the question "is Copy properly implemented" For IGES, answer is always True.

Copy ("Deep") from <entfrom> to <entto> (same type) by using a CopyTool which provides its working Map. For IGESEntities, Copies general data (Directory Part, List of Properties) and call OwnCopyCase.

Copies parameters which are specific of each Type of Entity.

Renewing of Implied References. For IGESEntities, Copies general data(List of Associativities) and calls OwnRenewCase.

Renews parameters which are specific of each Type of Entity : the provided default does nothing, but this method may be redefined as required.

Initializes a directory field as an Entity of any kind See DirFieldEntity for more details.

Initializes Transf, or erases it if <ent> is given Null.

Initializes View, or erases it if <ent> is given Null.

Returns True if an entity has one and only one parent, defined by a SingleParentEntity Type Associativity (explicit sharing). Thus, implicit sharing remains defined at model level (see class ToolLocation).

Returns the Unique Parent (in the sense given by HasOneParent) Error if there is none or several.

Returns Location given by Transf in Directory Part (see above) It must be considered for local definition : if the Entity is set in a "Parent", that one can add its one Location, but this is not taken in account here : see CompoundLocation for that. If no Transf is defined, returns Identity If Transf is itself compound, gives the final result.

Returns Location considered for Vectors, i.e. without its Translation Part. As Location, it gives local definition.

Returns Location by taking in account a Parent which has its own Location : that one will be combined to that of <me> The Parent is considered only if HasOneParent is True, else it is ignored and CompoundLocation = Location.

Clears the IGES file Start Section.

Sets a new Start section from a list of strings. If copy is false, the Start section will be shared. Any modifications made to the strings later on, will have an effect on the Start section. If copy is true (default value), an independent copy of the strings is created and used as the Start section. Any modifications made to the strings later on, will have no effect on the Start section.
