CircularBuffer< T >::CircularBuffer ( )

inline

Default Constructor

Definition at line 50 of file CircularBuffer.h.

template<class T>

CircularBuffer< T >::CircularBuffer ( const CircularBuffer< T > & rhs )

inline

Copy Constructor. Deep copies the data from the rhs instance to this instance

Parameters

const CircularBuffer &rhs: ths instance the data and settings will be copied from

Definition at line 64 of file CircularBuffer.h.

template<class T>

CircularBuffer< T >::CircularBuffer ( unsigned int bufferSize )

inline

Init Constructor. Resizes the buffer to the size set by bufferSize.

Parameters

unsigned int bufferSize: sets the size of the buffer

Definition at line 90 of file CircularBuffer.h.

template<class T>

virtual CircularBuffer< T >::~CircularBuffer ( )

inlinevirtual

Default Destructor. Cleans up any memory assigned by the buffer.

Definition at line 99 of file CircularBuffer.h.

Member Function Documentation

template<class T>

void CircularBuffer< T >::clear ( )

inline

Clears the buffer, setting the size to 0.

Definition at line 271 of file CircularBuffer.h.

template<class T>

T CircularBuffer< T >::getBack ( ) const

inline

Returns the most recent value added to the buffer.

Returns: returns the most recent value added to the buffer

Definition at line 357 of file CircularBuffer.h.

template<class T>

bool CircularBuffer< T >::getBufferFilled ( ) const

inline

Returns true if the buffer has been filled. If the buffer has not been initialized then this function will always return false.

Returns: returns true if the buffer has been filled, false otherwise

Definition at line 322 of file CircularBuffer.h.

template<class T>

Vector< T > CircularBuffer< T >::getData ( const bool rawBuffer = false ) const

inline

Gets the data in the CircularBuffer's internal buffer as a std::vector. The argument, rawBuffer, controls if the function returns (if rawBuffer = true ) the entire contents of the internal buffer (with unsorted values and a constant size regardless on whether it is filled), or the current contents of the Circular Buffer in order from oldest to newest (if rawBuffer = false).

Returns: returns a std::vector with the data in the buffer

Definition at line 294 of file CircularBuffer.h.

template<class T>

bool CircularBuffer< T >::getInit ( ) const

inline

Returns true if the buffer has been initialized.

Returns: returns true if the buffer has been initialized, false otherwise

Definition at line 315 of file CircularBuffer.h.

template<class T>

unsigned int CircularBuffer< T >::getNumValuesInBuffer ( ) const

inline

Returns the number of values in the buffer.

Returns: returns the number of values in the buffer

Definition at line 336 of file CircularBuffer.h.

template<class T>

unsigned int CircularBuffer< T >::getReadPointerPosition ( ) const

inline

Returns the current position of the read pointer.

Returns: returns the current position of the read pointer

Definition at line 343 of file CircularBuffer.h.

template<class T>

unsigned int CircularBuffer< T >::getSize ( ) const

inline

Returns the size of the buffer.

Returns: returns the size of the bufer

Definition at line 329 of file CircularBuffer.h.

template<class T>

unsigned int CircularBuffer< T >::getWritePointerPosition ( ) const

inline

Returns the current position of the write pointer.

Returns: returns the current position of the write pointer

Definition at line 350 of file CircularBuffer.h.

template<class T>

CircularBuffer< T >::GRT_DEPRECATED_MSG	(	"Use getData() instead!"	,
		std::vector< T > getDataAsVector()	const
	)

Deprecated:: This function is now deprecated, you should use getData instead! Gets all the data in the buffer as a std::vector.

Returns: returns a vector will all the data in the buffer

template<class T>

T& CircularBuffer< T >::operator() ( const unsigned int & index )

inline

This is a special access operator that will return the value at the specific index (regardless of the position of the read pointer).

Parameters

const unsigned int &index: the index of the element you want access to, should be in the range [0 bufferSize-1]

Returns: returns a reference to the element at the index

Definition at line 156 of file CircularBuffer.h.

template<class T>

const T& CircularBuffer< T >::operator() ( const unsigned int & index ) const

inline

This is a special const access operator that will return the value at the specific index (regardless of the position of the read pointer).

Parameters

const unsigned int &index: the index of the element you want access to, should be in the range [0 bufferSize-1]

Returns: returns a const reference to the element at the index

Definition at line 166 of file CircularBuffer.h.

template<class T>

CircularBuffer& CircularBuffer< T >::operator= ( const CircularBuffer< T > & rhs )

inline

Sets the equals operator. Defines how the data will be copied from the rhs instance to this instance.

Parameters

const CircularBuffer &rhs: the instance the data will be copied from

Returns: returns a reference to this instance

Definition at line 111 of file CircularBuffer.h.

template<class T>

T& CircularBuffer< T >::operator[] ( const unsigned int & index )

inline

This is the main access operator and will return a value relative to the current read pointer.

Parameters

const unsigned int &index: the index of the element you want access to, should be in the range [0 bufferSize-1]

Returns: returns a reference to the element at the index

Definition at line 136 of file CircularBuffer.h.

template<class T>

const T& CircularBuffer< T >::operator[] ( const unsigned int & index ) const

inline

This is the constant access operator and will return a value relative to the current read pointer.

Parameters

const unsigned int &index: the index of the element you want access to, should be in the range [0 bufferSize-1]

Returns: returns a const reference to the element at the index

Definition at line 146 of file CircularBuffer.h.

template<class T>

bool CircularBuffer< T >::push_back ( const T & value )

inline

Push the new value into the end of the buffer, this will move both the read and write pointers.

Parameters

const T &value: the value that should be added to the end of the buffer

Returns: returns true if the value was pushed, false otherwise

Definition at line 213 of file CircularBuffer.h.

template<class T>

bool CircularBuffer< T >::reset ( )

inline

Returns: returns true if the buffer was reset, false otherwise

Definition at line 261 of file CircularBuffer.h.

template<class T>

bool CircularBuffer< T >::resize ( const unsigned int newBufferSize )

inline

Resizes the buffer to the newBufferSize, which must be greater than zero.

Parameters

const unsigned int newBufferSize: the new size of the buffer

Returns: returns true if the buffer was resized

Definition at line 176 of file CircularBuffer.h.

template<class T>

bool CircularBuffer< T >::resize	(	const unsigned int	newBufferSize,
		const T &	defaultValue
	)

inline

Resizes the buffer to the newBufferSize, which must be greater than zero, and sets all the values to the default value.

Parameters

const	unsigned int newBufferSize: the new size of the buffer
const	T &defaultValue: the default value that will be copied to every element

Returns: returns true if the buffer was resized

Definition at line 187 of file CircularBuffer.h.

template<class T>

bool CircularBuffer< T >::setAllValues ( const T & value )

inline

Sets all the values in the buffer to the value.

Parameters

const T &value: the value that will be copied to all the elements in the buffer

Returns: returns true if the buffer was updated, false otherwise
