Constructor & Destructor Documentation
◆ circularBufferIndex() [1/2]
|
inline |
Default c'tor.
Definition at line 469 of file circularBuffer.hpp.
◆ circularBufferIndex() [2/2]
|
inlineexplicit |
Sizing constructor.
Sets the maximum size of the buffer. Note that this will not be the size until a full set of entries have been added to the buffer.
- Parameters
-
[in] maxEnt the maximum number of entries this buffer will hold
Definition at line 477 of file circularBuffer.hpp.
Member Function Documentation
◆ at() [1/2]
|
inline |
Interface implementation for entry access.
Accesses the idx-th element relative to refEntry, using the pre-populated indices to wrap
- Returns
- a reference to the idx-th element
- Parameters
-
[in] refEntry the entry to start counting from [in] idx the index of the entry to access
Definition at line 513 of file circularBuffer.hpp.
References mx::sigproc::circularBufferBase< circularBufferIndex< _storedT, _indexT >, _storedT, _indexT >::m_buffer.
◆ at() [2/2]
|
inline |
Interface implementation for entry access, const version.
Accesses the idx-th element relative to refEntry, using the pre-populated indices to wrap
This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
- Returns
- a const reference to the idx-th element
- Parameters
-
[in] refEntry the entry to start counting from [in] idx the index of the entry to access
Definition at line 527 of file circularBuffer.hpp.
References mx::sigproc::circularBufferBase< circularBufferIndex< _storedT, _indexT >, _storedT, _indexT >::m_buffer.
◆ setMaxEntries()
|
inline |
Interface implementation for maxEntries.
Resizes and populates the indices array.
- Parameters
-
[in] maxEnt the maximum number of entries this buffer will hold
Definition at line 484 of file circularBuffer.hpp.
References mx::sigproc::circularBufferIndex< _storedT, _indexT >::m_indices, and mx::sigproc::circularBufferBase< circularBufferIndex< _storedT, _indexT >, _storedT, _indexT >::m_maxEntries.
◆ setWrap()
|
inline |
Interface implementation for wrapping setup after the startup phase.
This is called after maxEntries have been added.
Definition at line 504 of file circularBuffer.hpp.
◆ setWrapStartup()
|
inline |
Interface implementation for wrapping setup during the startup phase.
This is called before maxEntries have been added.
Definition at line 497 of file circularBuffer.hpp.
