## Member Function Documentation

virtual void HRCParser::setErrorHandler | ( | ErrorHandler * | eh | ) | `[pure virtual]`

Error Handler, used to inform application about different error conditions.

Parameters:

  | eh | ErrorHandler instance, or null to drop error handling.

virtual void HRCParser::loadSource | ( | InputSource * | is | ) | `[pure virtual]`

Loads HRC from specified InputSource stream.

Referred HRC file can contain prototypes and real types definitions. If it contains just prototype definition, real type load must be performed before using with loadType() method

Parameters:

  | is | InputSource stream of HRC file

virtual FileType* HRCParser::enumerateFileTypes | ( | int | index | ) | `[pure virtual]`

Enumerates sequentially all prototypes.

Parameters:

  | index | index of type.

Returns:
  Requested type, or null, if index is too big

virtual FileType* HRCParser::getFileType | ( | const String * | name | ) | `[pure virtual]`

Parameters:

  | name | Requested type name.

Returns:
  File type, or null, there are no type with specified name.

virtual FileType* HRCParser::chooseFileType | ( | const String * | fileName,
|  | const String * | firstLine,
|  | int | typeNo = `0`
| ) | `[pure virtual]`

Searches and returns the best type for specified file.

This method uses fileName and firstLine parameters to perform selection of the best HRC type from database.

Parameters:

  | fileName | Name of file
  | firstLine | First line of this file, could be null
  | typeNo | Sequential number of type, if more than one type satisfy these input parameters.

virtual const Region* HRCParser::getRegion | ( | const String * | name | ) | `[pure virtual]`

Returns region by name.

Note:
  Also loads referred type, if it is not yet loaded.

virtual const String* HRCParser::getVersion | ( |  | ) | `[pure virtual]`

| HRC base version. Usually this is the 'version' attribute of 'hrc' element of the first loaded HRC file.
