144 | @brief This class serves to expand links used within configuration files. |
---|
145 | |
---|
146 | Value of any type but string can be linked to some other value of the same type |
---|
147 | defined elsewhere in the current configuration file or even in some different |
---|
148 | configuration file. |
---|
149 | |
---|
150 | Link have three parts, \<name\> : \<path\> \<\@filename\>. Field \<name\> contains the |
---|
151 | name of the new setting, \<path\> is the relative path to the referenced setting, which |
---|
152 | has to be taken from the %root Setting element. The last part \<\@filename\> is optional, |
---|
153 | it contains filename in the case the link should refer to a variable stored in a different |
---|
154 | file. From the previous part \<path\>, it has to be separated by '@'. |
---|
155 | |
---|
156 | \code |
---|
157 | ... |
---|
158 | jardovo : |
---|
159 | { |
---|
160 | class = "Car"; |
---|
161 | year = 1992; |
---|
162 | manufacturer = "liaz"; |
---|
163 | kilometers = 1555000; |
---|
164 | }; |
---|
165 | ondrejovo : |
---|
166 | { |
---|
167 | class = "Bike"; |
---|
168 | year = 1996; |
---|
169 | manufacturer = "author"; |
---|
170 | electricLights = true; |
---|
171 | matr = ( 2, 2, [ 1.0, 0.0, 0.0, 1.0 ] ); |
---|
172 | }; |
---|
173 | |
---|
174 | #this is the example of local link to another mean of transport |
---|
175 | elisky = "jardovo"; |
---|
176 | |
---|
177 | ... |
---|
178 | |
---|
179 | # And this link is external link pointing to the file "other_cars.cfg" stored in the |
---|
180 | # same directory. In that file, it refers to the local Setting "magic_cars.skubankovo". |
---|
181 | kati = "magic_cars.skubankovo@other_cars.cfg"; |
---|
182 | |
---|
183 | ... |
---|
184 | \endcode |
---|
185 | |
---|
186 | When you want to expand a possible linked setting "element" within your code, it has to be treated this way: |
---|
187 | |
---|
188 | \code |
---|
189 | ... |
---|
190 | |
---|
191 | const SettingResolver link( element ); |
---|
192 | |
---|
193 | ... |
---|
194 | |
---|
195 | int len = link.result.getLength(); |
---|
196 | |
---|
197 | ... |
---|
198 | \endcode |
---|
199 | |
---|
200 | The whole point is that a resolved link (class member #result, i.e., "link.result" in the previous example) could point |
---|
201 | into a different configuration file. In that case there has to be an UIFile instance managing reading from this |
---|
202 | file. As the libconfig::Config deletes all its Settings when dealocated, UIFile must not be dealocated until all |
---|
203 | the necessary operation on the linked Setting are finished (otherwise, the link #result would be invalid just after |
---|
204 | the UIFile dealocation). And that is exactly the mechanism implemented within SettingResolver class. It assures, |
---|
205 | that the #result Setting reference is valid within the scope of SettingResolver instance. |
