An expression converter converts an XML expression represented by an IConfigurationElement or Element (DOM) subtree into a corresponding expression tree.
An expression converter manages a list of ElementHandlers. Element handlers are responsible to do the actual conversion. The element handlers build a chain of responsibility.

berry::ExpressionConverter::ExpressionConverter | ( | const QList< SmartPointer< ElementHandler > > & | handlers | ) |
Creates a new expression converter with the given list of element handlers. The element handlers build a chain of responsibility meaning that the first handler in the list is first used to convert the configuration element. If this handler isn't able to convert the configuration element the next handler in the array is used.
handlers | the array of element handlers |
