scala - How to access functions from traits? -

i new scala , trying use trait"s". code looks this.

trait codehelper {   def functioncall(x: integer){       def valuechecker(){       /*code perform required operation*/       }   } } 

i access trait main scala class called "valuecreator" follows:

 class valuecreator() extends baseclass() codehelper {     val value = valuechecker()   } 

however code not work. error in main class "valuecreator" saying

"not found: value valuechecker"

could please tell me how access function trait? thank in advance time

your definition of valuechecker inside method, functioncaller, called nested method. means former method function local , available functioncaller. if want make visible @ trait level, you'll need make separate method:

trait codehelper {   def functioncall(x: int) {   }    def valuechecker() {      /*code perform required operation*/   } } 

although, seems want call functioncaller perhaps?

class valuecreator extends baseclass codehelper {     val value = functioncaller(2) } 

as side note, class names in scala pascal case, meaning first letter upper case, not lower case.
