Constructor & Destructor Documentation

template<class T >

RTT::base::BufferUnSync< T >::BufferUnSync	(	size_type	size,
		const Options &	options = `Options()`
	)

inline

Create an uninitialized buffer of size size.

Definition at line 71 of file BufferUnSync.hpp.

template<class T >

RTT::base::BufferUnSync< T >::BufferUnSync	(	size_type	size,
		param_t	initial_value,
		const Options &	options = `Options()`
	)

inline

Create a buffer of size size.

Member Function Documentation

template<class T >

size_type RTT::base::BufferUnSync< T >::capacity ( ) const

inlinevirtual

Returns the maximum number of items that can be stored in the buffer.

Returns: maximum number of items.

Implements RTT::base::BufferBase.

Definition at line 197 of file BufferUnSync.hpp.

template<class T >

void RTT::base::BufferUnSync< T >::clear ( )

inlinevirtual

Clears all contents of this buffer.

Implements RTT::base::BufferBase.

Definition at line 205 of file BufferUnSync.hpp.

template<class T >

virtual bool RTT::base::BufferUnSync< T >::data_sample	(	param_t	sample,
		bool	reset = `true`
	)

inlinevirtual

Initializes this buffer with a data sample, such that for dynamical allocated types T, the buffer can reserve place to hold these elements.

Parameters

sample	the data sample
reset	enforce reinitialization even if this operation clears all data.

Returns: true if the buffer was successfully (re)initialized.

Postcondition: Calling this function causes all data in the buffer to be lost and the size being reset to zero.

Implements RTT::base::BufferInterface< T >.

Definition at line 85 of file BufferUnSync.hpp.

template<class T >

virtual value_t RTT::base::BufferUnSync< T >::data_sample ( ) const

inlinevirtual

Reads back a data sample.

Implements RTT::base::BufferInterface< T >.

Definition at line 96 of file BufferUnSync.hpp.

template<class T >

virtual size_type RTT::base::BufferUnSync< T >::dropped ( ) const

inlinevirtual

Returns the number of dropped samples, because the buffer was full

Implements RTT::base::BufferBase.

Definition at line 217 of file BufferUnSync.hpp.

template<class T >

bool RTT::base::BufferUnSync< T >::empty ( ) const

inlinevirtual

Check if this buffer is empty.

Returns: true if size() == 0

Implements RTT::base::BufferBase.

Definition at line 209 of file BufferUnSync.hpp.

template<class T >

bool RTT::base::BufferUnSync< T >::full ( ) const

inlinevirtual

Check if this buffer is full.

Returns: true if size() == capacity()

Implements RTT::base::BufferBase.

Definition at line 213 of file BufferUnSync.hpp.

template<class T >

FlowStatus RTT::base::BufferUnSync< T >::Pop ( reference_t item )

inlinevirtual

Read the oldest value from the buffer.

Parameters

item	is to be set with a value from the buffer.

Returns: true if something was read.

Implements RTT::base::BufferInterface< T >.

Definition at line 155 of file BufferUnSync.hpp.

template<class T >

size_type RTT::base::BufferUnSync< T >::Pop ( std::vector< value_t > & items )

inlinevirtual

Read the whole buffer.

Parameters

items is to be filled with all values in the buffer, with items.begin() the oldest value.

Returns: the number of items read.

Implements RTT::base::BufferInterface< T >.

Definition at line 165 of file BufferUnSync.hpp.

template<class T >

value_t* RTT::base::BufferUnSync< T >::PopWithoutRelease ( )

inlinevirtual

Returns a pointer to the first element in the buffer. The pointer is only garanteed to stay valid until the next pop operation.

Note the pointer needs the be released by calling Release on the buffer.

Returns: a pointer to a sample or Zero if buffer is empty

Implements RTT::base::BufferInterface< T >.

Definition at line 177 of file BufferUnSync.hpp.

template<class T >

bool RTT::base::BufferUnSync< T >::Push ( param_t item )

inlinevirtual

Write a single value to the buffer.

Parameters

item	the value to write

Returns: false if the buffer is full.

Implements RTT::base::BufferInterface< T >.

Definition at line 106 of file BufferUnSync.hpp.

template<class T >

size_type RTT::base::BufferUnSync< T >::Push ( const std::vector< value_t > & items )

inlinevirtual

Write a sequence of values to the buffer.

Parameters

items the values to write

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

Implements RTT::base::BufferInterface< T >.

Definition at line 124 of file BufferUnSync.hpp.

template<class T >

void RTT::base::BufferUnSync< T >::Release ( value_t * item )

inlinevirtual

Releases the pointer

Parameters

item	pointer aquired using PopWithoutRelease()

Implements RTT::base::BufferInterface< T >.

Definition at line 190 of file BufferUnSync.hpp.

template<class T >

size_type RTT::base::BufferUnSync< T >::size ( ) const

inlinevirtual

Returns the actual number of items that are stored in the buffer.

Returns: number of items.

Implements RTT::base::BufferBase.

Definition at line 201 of file BufferUnSync.hpp.
