dojo.AdapterRegistry

A registry to make contextual calling/searching easier. Objects of this class keep list of arrays in the form [name, check, wrap, directReturn] that are used to determine what the contextual result of a set of checked arguments is. All check/wrap functions in this registry should be of the same arity (have the same number of arguments).

Example

require(["dojo/AdapterRegistry"], function(reg){
    reg.register("handleString",
      dojo.isString,
      function(str){
        // do something with the string here
      }
    );
    reg.register("handleArr",
      dojo.isArray,
      function(arr){
        // do something with the array here
      }
    );

    // now we can pass reg.match() *either* an array or a string and the value we pass will get handled by the right function
    reg.match("someValue"); // will call the first function
    reg.match(["someValue"]); // will call the second
});

require(["dojo/AdapterRegistry"], function(reg){ reg.register("handleString", dojo.isString, function(str){ // do something with the string here } ); reg.register("handleArr", dojo.isArray, function(arr){ // do something with the array here } ); // now we can pass reg.match() *either* an array or a string and the value we pass will get handled by the right function reg.match("someValue"); // will call the first function reg.match(["someValue"]); // will call the second });

There is also possible to unregister adapter from registry however there are performance problems on a large registry.

require(["dojo/AdapterRegistry"], function(reg){
    reg.unregister("handleArr");
});

require(["dojo/AdapterRegistry"], function(reg){ reg.unregister("handleArr"); });
