Detailed Description

template<class T>
class RTT::internal::ListLocked< T >

A simple lock-based list implementation to append or erase data of type T.

Note:
The mutex used by this implementation is recursive in order to allow apply() to call apply() recursively. Erasing self (using clear() or erase()) from within apply() is not supported and may lead to abnormal program termination.
Parameters:
T The value type to be stored in the list. Example : ListLocked is a list which holds values of type A.

Member Function Documentation

template<class T>
size_t RTT::internal::ListLocked< T >::append ( const std::vector< T > &  items  )  [inline]

Append a sequence of values to the list.

Parameters:
items the values to append.
Returns:
the number of values written (may be less than items.size())

Definition at line 214 of file ListLocked.hpp.

template<class T>
bool RTT::internal::ListLocked< T >::append ( value_t  item  )  [inline]

Append a single value to the list.

Parameters:
d the value to write
Returns:
false if the list is full.

Definition at line 182 of file ListLocked.hpp.

template<class T>
template<class Function >
void RTT::internal::ListLocked< T >::apply ( Function  func  )  [inline]

Apply a function to the elements of the whole list.

Parameters:
func The function to apply.
Note:
func may not call clear() or erase() on the current element of this list.

Definition at line 274 of file ListLocked.hpp.

template<class T>
value_t RTT::internal::ListLocked< T >::back (  )  const [inline]

Returns the last element of the list.

Definition at line 171 of file ListLocked.hpp.

template<class T>
template<typename Pred >
bool RTT::internal::ListLocked< T >::delete_if ( Pred  pred  )  [inline]

Erase a value from the list.

Parameters:
function each elements for which pred returns true are removed
Returns:
true if at least one element has been removed
Note:
This function is only real-time if the destructor and copy-constructor of of T is real-time.

Definition at line 245 of file ListLocked.hpp.

bool RTT::internal::ListLocked< T >::empty (  )  const [inline]

Definition at line 123 of file ListLocked.hpp.

template<class T>
bool RTT::internal::ListLocked< T >::erase ( value_t  item  )  [inline]

Erase a value from the list.

Parameters:
item is to be erased from the list.
Returns:
true if found and erased.

Definition at line 230 of file ListLocked.hpp.

template<class T>
template<class Function >
value_t RTT::internal::ListLocked< T >::find_if ( Function  func,
value_t  blank = value_t() 
) [inline]

Find an item in the list such that func( item ) == true.

Parameters:
blank The value to return if not found.
Returns:
The item that matches func(item) or blank if none matches.

Definition at line 288 of file ListLocked.hpp.

template<class T>
void RTT::internal::ListLocked< T >::give_back ( Cont *  cont  )  [inline, private]

This is a dispose function for remove_and_dispose_if It takes a pointer as argument.

Parameters:
cont 

Definition at line 302 of file ListLocked.hpp.

template<class T>
void RTT::internal::ListLocked< T >::grow ( size_t  items = 1  )  [inline]

Grow the capacity to contain at least n additional items. This method tries to avoid too much re-allocations, by growing a bit more than required every N invocations and growing nothing in between.

Parameters:
items The number of items to at least additionally reserve.

Definition at line 136 of file ListLocked.hpp.

template<class T>
bool RTT::internal::ListLocked< T >::is_item ( value_t  item,
const Cont &  cont 
) [inline, private]

This is a predicate function for remove_and_dispose_if It takes a reference as argument.

Parameters:
item 
cont 
Returns:

Definition at line 327 of file ListLocked.hpp.

template<class T>
void RTT::internal::ListLocked< T >::reserve ( size_t  lsize  )  [inline]

Reserve a capacity for this list.

Parameters:
lsize the minimal number of items this list will be able to hold. Will not drop below the current capacity() and this method will do nothing if lsize < this->capacity().

Definition at line 163 of file ListLocked.hpp.

template<class T>
void RTT::internal::ListLocked< T >::shrink ( size_t  items = 1  )  [inline]

Shrink the capacity with at most n items. This method does not actually free memory, it just prevents a (number of) subsequent grow() invocations to allocate more memory.

Parameters:
items The number of items to at most remove from the capacity.
