Typedefs

◆ Ptr

typedef QExplicitlySharedDataPointer<DynamicContext> QPatternist::DynamicContext::Ptr

Definition at line 98 of file qdynamiccontext_p.h.

◆ TemplateParameterHash

typedef QHash<QXmlName, QExplicitlySharedDataPointer<Expression> > QPatternist::DynamicContext::TemplateParameterHash

Carries template parameters at runtime.

The key is the name of the parameter, and the value the Expression which supplies the value.

Functions

◆ addNodeModel()

virtual void QPatternist::DynamicContext::addNodeModel ( const QAbstractXmlNodeModel::Ptr &  nm)
pure virtual

Whenever a tree gets built, this function is called. DynamicContext has the responsibility of keeping a copy of nm, such that it doesn't go out of scope, since no one else will reference nm.

I think this is currently only used for temporary node trees. In other cases they are stored in the ExternalResourceLoader.

The caller guarantees that nm is not null.

Implemented in QPatternist::GenericDynamicContext, QPatternist::TemporaryTreesRedirectingContext, and QPatternist::DelegatingDynamicContext.

◆ globalItemCacheCell()

virtual ItemCacheCell& QPatternist::DynamicContext::globalItemCacheCell ( const VariableSlotID  slot)
pure virtual

Same as itemCacheCell(), but is only used for global varibles. This is needed because sometimes stack frames needs to be created for other kinds of variables(such as in the case of user function calls), while the global variable(s) needs to continue to use the same cache, instead of one for each new stack frame, typically an instance of StackContextBase.

This has two effects:

  • It's an optimization. Instead of that a global variable gets evaluated each time a user function is called, think recursive functions, it's done only once.
  • Query stability, hence affects things like node identity and therefore conformance. Hence affects for instance what nodes a query returns, since node identity affect node deduplication.

Implemented in QPatternist::GenericDynamicContext, and QPatternist::DelegatingDynamicContext.

◆ templateParameterStore()

virtual TemplateParameterHash& QPatternist::DynamicContext::templateParameterStore ( )
pure virtual

When a template is called, this member carries the template parameters.

Hence this is similar to the other variable stack functions such as rangeVariable() and expressionVariable(), the difference being that the order of template parameters as well as its arguments can appear in arbitrary order. Hence the name is used to make the order insignificant.

Implemented in QPatternist::DelegatingDynamicContext, and QPatternist::StackContextBase< DynamicContext >.
