Public Member Functions

virtual void Formats (TColStd_SequenceOfExtendedString &Formats)
 Returns the format name Formats
representing the format supported for
application documents.
This virtual function is to be redefined for each
specific application.

virtual Standard_CString ResourcesName ()
 methods from TDocStd_Application
================================
More...
 
virtual void InitDocument (const Handle< TDocStd_Document > &aDoc) const
 Set XCAFDoc_DocumentTool attribute
More...
 
- Public Member Functions inherited from TDocStd_Application
Standard_Boolean IsDriverLoaded () const
 Check if meta data driver was successfully loaded
by the application constructor
More...
 
virtual Handle_Resource_Manager Resources ()
 create (if not done) a Manager using ResourcesName
method.
More...
 
Standard_Integer NbDocuments () const
 returns the number of documents handled by the current applicative session.
More...
 
void GetDocument (const Standard_Integer index, Handle< TDocStd_Document > &aDoc) const
 
 Constructs the new document aDoc. <br>

aDoc is identified by the index index which is
any integer between 1 and n where n is the
number of documents returned by NbDocument.
Example
Handle(TDocStd_Application)
anApp;
if (!CafTest::Find(A)) return 1;
Handle(TDocStd) aDoc;
Standard_Integer nbdoc = anApp->NbDocuments();
for (Standard_Integer i = 1; i <= nbdoc; i++) {
aApp->GetDocument(i,aDoc);
More...

 
virtual void NewDocument (const TCollection_ExtendedString &format, Handle< TDocStd_Document > &aDoc)
 
 Constructs the empty new document aDoc. <br>

This document will have the format format.
If InitDocument is redefined for a specific
application, the new document is handled by the
applicative session.
More...

 
void Close (const Handle< TDocStd_Document > &aDoc)
 Close the given document. the document is not any more
handled by the applicative session.
More...
 
Standard_Integer IsInSession (const TCollection_ExtendedString &path) const
 
  Returns an index for the document found in the <br>

path path in this applicative session.
If the returned value is 0, the document is not
present in the applicative session.
This method can be used for the interactive part
of an application. For instance, on a call to
Open, the document to be opened may already
be in memory. IsInSession checks to see if this
is the case. Open can be made to depend on
the value of the index returned: if IsInSession
returns 0, the document is opened; if it returns
another value, a message is displayed asking the
user if he wants to override the version of the
document in memory.
Example:
Standard_Integer insession = A->IsInSession(aDoc);
if (insession > 0) {
cout << "document " << insession << " is already in session" << endl;
return 0;
}
More...

 
PCDM_ReaderStatus Open (const TCollection_ExtendedString &path, Handle< TDocStd_Document > &aDoc)
 
 Retrieves the document aDoc stored under the <br>

name aName in the directory directory.
In order not to override a version of aDoc which
is already in memory, this method can be made
to depend on the value returned by IsInSession.
More...

 
PCDM_StoreStatus SaveAs (const Handle< TDocStd_Document > &aDoc, const TCollection_ExtendedString &path)
 Save the active document in the file <name> in the
path <path> ; o verwrites the file if it already exists.
More...
 
PCDM_StoreStatus Save (const Handle< TDocStd_Document > &aDoc)
 
 Save aDoc active document. <br>

Exceptions:
Standard_NotImplemented if the document
was not retrieved in the applicative session by using Open.
More...

 
PCDM_StoreStatus SaveAs (const Handle< TDocStd_Document > &aDoc, const TCollection_ExtendedString &path, TCollection_ExtendedString &theStatusMessage)
 Save the active document in the file <name> in the
path <path> . overwrite the file if it
already exist.
More...
 
PCDM_StoreStatus Save (const Handle< TDocStd_Document > &aDoc, TCollection_ExtendedString &theStatusMessage)
 Save the document overwriting the previous file
More...
 
- Public Member Functions inherited from CDF_Application
void Open (const Handle< CDM_Document > &aDocument)
 puts the document in the current session directory
and calls the virtual method Activate on it.
More...
 
CDM_CanCloseStatus CanClose (const Handle< CDM_Document > &aDocument)
 
void Close (const Handle< CDM_Document > &aDocument)
 removes the document of the current session directory
and closes the document;
More...
 
Handle_CDM_Document Retrieve (const TCollection_ExtendedString &aFolder, const TCollection_ExtendedString &aName, const Standard_Boolean UseStorageConfiguration=Standard_True)
 
 This method retrieves a document from the database. <br>
     If the Document references other documents which have <br>
     been updated, the latest version of these documents will <br>
     be used if {UseStorageConfiguration} is Standard_True. <br>
      The content of {aFolder}, {aName} and {aVersion} depends on <br>
      the Database Manager system. If the DBMS is only based on <br>
      the OS, {aFolder} is a directory and {aName} is the name of a <br>
      file. In this case the use of the syntax with {aVersion} <br>
      has no sense. For example: <br>


Handle(CDM_Document) theDocument=myApplication->Retrieve("/home/cascade","box.dsg");
If the DBMS is EUCLID/Design Manager, {aFolder}, {aName}
have the form they have in EUCLID/Design Manager. For example:

Handle(CDM_Document) theDocument=myApplication->Retrieve("|user|cascade","box");

Since the version is not specified in this syntax, the latest wil be used.
A link is kept with the database through an instance of CDM_MetaData

Handle_CDM_Document Retrieve (const TCollection_ExtendedString &aFolder, const TCollection_ExtendedString &aName, const TCollection_ExtendedString &aVersion, const Standard_Boolean UseStorageConfiguration=Standard_True)
 
  This method retrieves  a  document from the database. <br>
     If the  Document references other documents which have <br>
     been  updated, the  latest version of  these documents <br>
      will    be   used  if   {UseStorageConfiguration}  is <br>
     Standard_True.  --  If the DBMS is  only  based on the <br>
      OS, this syntax  should not be used. <br>


If the DBMS is EUCLID/Design Manager, {aFolder}, {aName}
and {aVersion} have the form they have in
EUCLID/Design Manager. For example:

Handle(CDM_Document) theDocument=myApplication->Retrieve("|user|cascade","box","2");
A link is kept with the database through an instance
of CDM_MetaData
