These methods give generic tools to read common data in the configuration files, such as arrays of float values or one VisuElement... It also defines a enumeration of detailed errors (see toolConfigFileError) when reading a file. All read elements are either from tokens (given g_strsplit()
) or strings.
gboolean (*configFileReadFunc) (gchar **lines, int nbLines, int position, VisuData *dataObj, GError **error);
This prototype corresponds to methods called when an entry is
found. The lines
argument is an array of lines read from the files.
These strings are copies and can be modified but not freed. There are
nbLines
and this value correspond to the number of lines defined
for the entry. The error
argument is used to store some text
messages and error ids. They should be in UTF8. The error
argument
must be initialised with (GError*)0. The position
argument give the number
of the first line given in lines
argument. If the dataObj
argument is not null,
some updates should be done with read values.
lines : |
an array of strings ; |
nbLines : |
an integer ; |
position : |
an integer ; |
dataObj : |
a VisuData object ; |
error : |
a pointer to a GError pointer. |
Returns : | TRUE if everything goes right, FALSE otherwise. |

error when reading a VisuElement name. |

error because too much VisuElement have been created. |
CONFIG_FILE_ERROR_CREATED_ELEMENT |
error when creating a new VisuElement. |
CONFIG_FILE_ERROR_VALUE |
error of file format, values read are out of bounds. |
