template<typename T >

virtual std::size_t iguana::ConcurrentParam< T >::GetSize ( ) const

pure virtual

Returns

the size of the internal data storage container

Implemented in iguana::MemoizedParam< T >, and iguana::SingleThreadParam< T >.

HasKey()

template<typename T >

virtual bool iguana::ConcurrentParam< T >::HasKey ( concurrent_key_t const key ) const

pure virtual

Parameters

key

the key

Returns

true if key key is used

Implemented in iguana::MemoizedParam< T >, and iguana::SingleThreadParam< T >.

IsEmpty()

template<typename T >

bool iguana::ConcurrentParam< T >::IsEmpty ( ) const

inline

Returns

true if no value has been saved

Definition at line 48 of file ConcurrentParam.h.

Load()

template<typename T >

virtual T const iguana::ConcurrentParam< T >::Load ( concurrent_key_t const key ) const

pure virtual

access a stored value

Parameters

key	the access key

Returns

the stored value

Implemented in iguana::MemoizedParam< T >, and iguana::SingleThreadParam< T >.

NeedsHashing()

template<typename T >

bool iguana::ConcurrentParam< T >::NeedsHashing ( ) const

inline

whether or not hashing is needed to use this parameter

Returns

true if hashing is needed

Definition at line 42 of file ConcurrentParam.h.

Save()

template<typename T >

virtual void iguana::ConcurrentParam< T >::Save ( T const & value, concurrent_key_t const key )

pure virtual

modify a value

Parameters

value	the value
key	the access key

Implemented in iguana::MemoizedParam< T >, and iguana::SingleThreadParam< T >.
