Introduction

Test of the ofParameter concept discussed at http://forum.openframeworks.cc/index.php?topic=7795.0

ofxParameter Problem Trivial saving / loading of parameters Creating user controls for parameters Extension agnostic (gui's, timelines, etc) Grouping parameters Features Instantiate and access have same syntax Save / Load / Autosave Global parameter register Folders / Subregisters / Tags Remote network access Enumerate parameters Tags By default every param has 'user' tag "user,timeline1" refers to During instantiation create parameter with both tags During access Parameters containing both tags Alternative names Control Argument Tweak InteractiveVariable Fiddle Variable Syntax Instantiation / access ofParam<T>[string parameter, string tag="user"] E.g. ofParam<float>["myValue"] Equivalent allocation ofParam<ofVec3f>["v"] ofParam<float>["v", 3] ofParam<T>[string parameter, int allocationSize=3, string tag="user"] File ofParamSave() / ofParamLoad() ofParametersSave(string filename="parameters.XML") ofParamSetAutoSave(bool b=true, string filename="parameters.xml") ofParamSetSaveable(string parameter, bool saveable) Tags ofParamAddTag(string paramName, string tag) ofParamRemoveTag(string paramName, string tag) Listing vector<ofParameter> ofParameterGetList(string tag="user") if tag="" then we return all parameters Debug ofParameterSetAccessCountEnabled(bool b) Turns on access counting. When enabled, we count how many accesses we make to each variable per frame ofParameterGetAccessCount(string param, bool cached=true)

• Returns how many times a parameter has been accessed in a frame
