Functions

◆ body()

virtual Expression::Ptr QPatternist::CallSite::body ( ) const

pure virtual

Returns the body of the function/template/component that is being called.

Implemented in QPatternist::UserFunctionCallsite, QPatternist::ApplyTemplate, and QPatternist::CallTemplate.

◆ callTargetDescription()

virtual CallTargetDescription::Ptr QPatternist::CallSite::callTargetDescription ( ) const

pure virtual

Implemented in QPatternist::UserFunctionCallsite, QPatternist::ApplyTemplate, and QPatternist::CallTemplate.

◆ configureRecursion()

virtual bool QPatternist::CallSite::configureRecursion ( const CallTargetDescription::Ptr & sign )

pure virtual

Called in the earliest stages of the compilation process. sign can be any function signature for a user declared function. If sign matches this UserFunctionCallsite, it means the UserFunction represented by sign is recursive and that this UserFunctionCallsite should take appropriate measures.

Returns: true if is recursive, otherwise false

Implemented in QPatternist::UserFunctionCallsite, QPatternist::ApplyTemplate, and QPatternist::CallTemplate.
