Detailed Description

template<class FUNCTION>
class bdlb::BDLB_SUNITERATORWORKAROUND< FUNCTION >

Provide an output iterator that calls an object of the (template parameter) type FUNCTION. If FUNCTION is a functor, de-referencing this iterator and assigning to the result (of dereferencing) will call the operator() of the functor with the assigned value as a parameter. Similarly, if FUNCTION if a function pointer type, assigning to the dereferenced iterator will call the function supplied at construction with the assigned value as a parameter.

Member Function Documentation

FunctionOutputIterator() [1/3]

template<class FUNCTION >

bdlb::BDLB_SUNITERATORWORKAROUND< FUNCTION >::FunctionOutputIterator

(

)

Create a FunctionOutputIterator object that, when an assignment is performed on the dereferenced object, will call a default constructed instance of the (template parameter) type FUNCTION passing the assigned value as the argument. Note that if FUNCTION is a function pointer type, then the default constructed FUNCTION will be 0, and the behavior when assigning to a dereferenced iterator will be undefined.

FunctionOutputIterator() [2/3]

template<class FUNCTION >

bdlb::BDLB_SUNITERATORWORKAROUND< FUNCTION >::FunctionOutputIterator ( const FUNCTION &  function )

explicit

Create FunctionOutputIterator object that, when an assignment is performed on the dereferenced object, will call the specified function passing the assigned value as the argument.

FunctionOutputIterator() [3/3]

template<class FUNCTION >

bdlb::BDLB_SUNITERATORWORKAROUND< FUNCTION >::FunctionOutputIterator ( const FunctionOutputIterator &  rhs )

default

Create a 'FunctionOutputIterator' object that, when an assignment is performed on the dereferenced object, will call the same function or functor used by the specified 'rhs' object.

operator*()

template<class FUNCTION >

AssignmentProxy bdlb::BDLB_SUNITERATORWORKAROUND< FUNCTION >::operator*

(

)

Return an object that can appear on the left-hand side of an assignment from TYPE. When a value is assigned to the returned value, invoke the functor or function indicated at construction supplying the assigned value as the parameter. This function is non-const in accordance with the input iterator requirements, even though *this is not modified. Note that if FUNCTION is a function pointer type and a valid function pointer was not supplied at construction, then the behavior when assigning to a dereferenced iterator will be undefined.

operator=()

template<class FUNCTION >

FunctionOutputIterator & bdlb::BDLB_SUNITERATORWORKAROUND< FUNCTION >::operator= ( const FunctionOutputIterator &  rhs )

default

Assign to this object the value of the specified 'rhs' object, and return a reference providing modifiable access to this object.
