Detailed Description

template<typename TSuperClass>
class QPatternist::StackContextBase< TSuperClass >

Base class for all DynamicContext classes that needs to supply variables. It has a new frame for local caches, position iterators, expressions, range variables, template parameters but notably continues to delegate global caches.

◆ StackContextBase() [2/2]

template<typename TSuperClass >

QPatternist::StackContextBase< TSuperClass >::StackContextBase ( const DynamicContext::Ptr & prevContext )

Construct a StackContextBase and passes prevContext to its super class. This constructor is typically used when the super class is DelegatingDynamicContext.
