## Public Member Functions
bool | DependentsIdentical (const std::vector< const TaggedObject * > &dependents, const std::vector< Number > &scalar_dependents) const
| This method returns true if the dependencies provided to this function are identical to the ones stored with the DependentResult.
void | DebugPrint () const
| Print information about this DependentResults.
Constructor, Destructors
| DependentResult (const T &result, const std::vector< const TaggedObject * > &dependents, const std::vector< Number > &scalar_dependents)
| Constructor, given all information about the result.
| ~DependentResult ()
| Destructor.
Accessor method.
bool | IsStale () const

void | Invalidate ()
| Invalidates the cached result.
const T & | GetResult () const
| Returns the cached result.
## Protected Member Functions
virtual void | RecieveNotification (NotifyType notify_type, const Subject *subject)
| This method is overloading the pure virtual method from the Observer base class.
## Private Member Functions
Default Compiler Generated Methods
(Hidden to avoid implicit creation/calling). These methods are not implemented and we do not want the compiler to implement them for us, so we declare them private and do not define them. This ensures that they will not be implicitly created/called.
| DependentResult ()
| Default Constructor.
| DependentResult (const DependentResult &)
| Copy Constructor.
void | operator= (const DependentResult &)
| Overloaded Equals Operator.
## Private Attributes
bool | stale_

## Detailed Description

### template<class T>
class Ipopt::DependentResult< T >

Templated class which stores one entry for the CachedResult class.

It stores the result (of type T), together with its dependencies (vector of TaggedObjects and vector of Numbers). It also stores a priority.

Definition at line 257 of file IpCachedResults.hpp.

Ipopt::DependentResult< T >::DependentResult | ( | const T & | result,
|  | const std::vector< const TaggedObject * > & | dependents,
|  | const std::vector< Number > & | scalar_dependents |
| ) |  |  | `[inline]`

Destructor.

Definition at line 381 of file IpCachedResults.hpp.

template<class T>

Ipopt::DependentResult< T >::DependentResult | ( |  | ) | `[private]`

Default Constructor.

template<class T>

Ipopt::DependentResult< T >::DependentResult | ( | const DependentResult< T > & |  | ) | `[private]`

Copy Constructor.

## Member Function Documentation

template<class T >

bool Ipopt::DependentResult< T >::IsStale | ( |  | ) | const`[inline]`

This returns true, if the DependentResult is no longer valid.

Definition at line 393 of file IpCachedResults.hpp.

template<class T >

void Ipopt::DependentResult< T >::Invalidate | ( |  | ) | `[inline]`

Invalidates the cached result.

Definition at line 399 of file IpCachedResults.hpp.

template<class T >

const T & Ipopt::DependentResult< T >::GetResult | ( |  | ) | const`[inline]`

Returns the cached result.

Definition at line 456 of file IpCachedResults.hpp.

template<class T >

bool Ipopt::DependentResult< T >::DependentsIdentical | ( | const std::vector< const TaggedObject * > & | dependents,
|  | const std::vector< Number > & | scalar_dependents |
| ) |  |  | const`[inline]`

This method returns true if the dependencies provided to this function are identical to the ones stored with the DependentResult.

Definition at line 419 of file IpCachedResults.hpp.

template<class T >

void Ipopt::DependentResult< T >::DebugPrint | ( |  | ) | const`[inline]`

Print information about this DependentResults.

Definition at line 467 of file IpCachedResults.hpp.

template<class T >

void Ipopt::DependentResult< T >::RecieveNotification | ( | NotifyType | notify_type,
|  | const Subject * | subject |
| ) |  |  | `[inline, protected, virtual]`

This method is overloading the pure virtual method from the Observer base class.

This method is called when a Subject registered for this Observer sends a notification. In this particular case, if this method is called with notify_type==NT_Changed or NT_BeingDeleted, then this results is marked as stale.

Implements Ipopt::Observer.

Definition at line 405 of file IpCachedResults.hpp.

template<class T>

void Ipopt::DependentResult< T >::operator= | ( | const DependentResult< T > & |  | ) | `[private]`

Overloaded Equals Operator.

Reimplemented from Ipopt::Observer.

## Member Data Documentation

template<class T>

bool Ipopt::DependentResult< T >::stale_`[private]`

Flag indicating, if the cached result is still valid.

A result becomes invalid, if the RecieveNotification method is called with NT_Changed

Definition at line 330 of file IpCachedResults.hpp.

template<class T>

const T Ipopt::DependentResult< T >::result_`[private]`

The value of the dependent results.

Definition at line 332 of file IpCachedResults.hpp.

template<class T>
