Error accessing an indexed item.
class AccessError( [code], [description], [extra] ) \ from Error( code, description, extra )
Error accessing an indexed item.
This error is generated when an array was accessed beyond its size, or a key was not found in a dictionary, or a requested property was not found in an object.
In addition, core, RTL and extension functions may raise this error when the semantic is appropriate (i.e. when providing them unexisting property names, or when requesting to access an unexisting range in an array).
