Detailed Description

Base class to work with CAD transfer properties. Stores the necessary settings for a single Provider type. Configures and creates special provider to transfer CAD files.

Nodes are grouped by Vendor's name and Format type. The Vendor name is not defined by default. The Format type is not defined by default. The supported CAD extensions are not defined by default. The import process is not supported. The export process is not supported.

The algorithm for standalone transfer operation: 1) Create new empty Node object 2) Configure the current Node 2.1) Use the external resource file to configure (Load) 2.2) Change the internal parameters directly: 2.2.1) Change field values of "GlobalParameters" 2.2.2) Change field values of "InternalParameters" 3) Create one-time transfer provider (BuildProvider) 4) Initiate the transfer process: 4.1) Import (if "::IsImportSupported: returns TRUE) 4.1.1) Validate the support of input format (::CheckContent or ::CheckExtension) 4.1.2) Use created provider's "::Read" method 4.2) Export (if "IsExportSupported: returns TRUE) 4.2.1) Use created provider's "::Write" method 5) Check the provider's output

Constructor & Destructor Documentation

pure virtual

◆ CheckContent()

virtual bool DE_ConfigurationNode::CheckContent ( const Handle< NCollection_Buffer > & theBuffer) const
virtual

Checks the file content to verify a format.

Parameters
[in]theBufferread stream buffer to check content
Returns
