185 |
|
* Abstract base class representing standard measurement units throughout |
186 |
|
* the script engine. These might be e.g. "dB" (deci Bel) for loudness, |
187 |
|
* "Hz" (Hertz) for frequencies or "s" for "seconds". These unit types can |
188 |
|
* combined with metric prefixes, for instance "kHz" (kilo Hertz), |
189 |
|
* "us" (micro second), etc. |
190 |
|
* |
191 |
|
* Originally the script engine only supported abstract integer values for |
192 |
|
* controlling any synthesis parameter or built-in function argument or |
193 |
|
* variable. Under certain situations it makes sense though for an |
194 |
|
* instrument script author to provide values in real, standard measurement |
195 |
|
* units to provide a more natural and intuitive approach for writing |
196 |
|
* instrument scripts, for example by setting the frequency of some LFO |
197 |
|
* directly to "20Hz" or reducing loudness by "-4.2dB". Hence support for |
198 |
|
* standard units in scripts was added as an extension to the NKSP script |
199 |
|
* engine. |
200 |
|
* |
201 |
|
* So a unit consists of 1) a sequence of metric prefixes as scale factor |
202 |
|
* (e.g. "k" for kilo) and 2) the actual unit type (e.g. "Hz" for Hertz). |
203 |
|
* The unit type is a constant feature of number literals and variables, so |
204 |
|
* once a variable was declared with a unit type (or no unit type at all) |
205 |
|
* then that unit type of that variable cannot be changed for the entire |
206 |
|
* life time of the script. This is different from the unit's metric |
207 |
|
* prefix(es) of variables which may freely be changed at runtime. |

/** @brief Parse-time check of function arguments. |
1024 |
|
* |
1025 |
|
* This method is called by the parser to let the built-in function |
1026 |
|
* perform its own, individual parse time checks on the arguments to be |
1027 |
|
* passed to the built-in function. So this method is the place for |
1028 |
|
* implementing custom checks which are very specific to the individual |
1029 |
|
* built-in function's purpose and its individual requirements. |
1030 |
|
* |
1031 |
|
* For instance the built-in 'in_range()' function uses this method to |
1032 |
|
* check whether the last 2 of their 3 arguments are of same data type |
1033 |
|
* and if not it triggers a parser error. 'in_range()' also checks |
1034 |
|
* whether all of its 3 arguments do have the same standard measuring |
1035 |
|
* unit type and likewise raises a parser error if not. |
1036 |
|
* |
1037 |
|
* For less critical issues built-in functions may also raise parser |
1038 |
|
* warnings instead. |
1039 |
|
* |
1040 |
|
* It is recommended that classes implementing (that is overriding) this |
1041 |
|
* method should always call their super class's implementation of this |
1042 |
|
* method to ensure their potential parse time checks are always |
1043 |
|
* performed as well. |
1044 |
|
* |
1045 |
|
* @param args - function arguments going to be passed for executing |
1046 |
|
* this built-in function later on |
1047 |
|
* @param err - the parser's error handler to be called by this method |
1048 |
|
* implementation to trigger a parser error with the |
1049 |
|
* respective error message text |
1050 |
|
* @param wrn - the parser's warning handler to be called by this method |
