Detailed Description

template<typename ContextType>
class tvm::WithGroup< ContextType >

A group of RAII contexts managed together.

Allows dynamically emplacing multiple context objects that are all exited (in reverse order) when the group is destroyed. ContextType must declare friend class With<ContextType> and provide EnterWithScope() / ExitWithScope() methods.

WithGroup<ConstraintContext> group;
group.Emplace(analyzer, cond1);  // constructs and enters
group.Emplace(analyzer, cond2);  // constructs and enters
// destructor: exits cond2, then cond1

Template Parameters

ContextType

The context type with EnterWithScope/ExitWithScope.

Constructor & Destructor Documentation

WithGroup() [1/3]

template<typename ContextType >

tvm::WithGroup< ContextType >::WithGroup ( )

default

WithGroup() [2/3]

template<typename ContextType >

tvm::WithGroup< ContextType >::WithGroup ( WithGroup< ContextType > &&  )

default

WithGroup() [3/3]

template<typename ContextType >

tvm::WithGroup< ContextType >::WithGroup ( const WithGroup< ContextType > &  )

delete

~WithGroup()

template<typename ContextType >

tvm::WithGroup< ContextType >::~WithGroup ( )

inline

Destructor — exits all contexts in reverse order.

On normal exit: if any ExitWithScope throws, the remaining contexts are still cleaned up, then the first exception is re-thrown.

During stack unwinding: all exceptions are swallowed to avoid std::terminate.

void tvm::WithGroup< ContextType >::Emplace ( Args &&...  args )

inline

Parameters
