Member Function Documentation
|
pure virtual |
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.
Implemented in RTT::base::BufferLockFree< T >, RTT::base::BufferLocked< T >, and RTT::base::BufferUnSync< T >.
|
pure virtual |
Reads back a data sample.
Implemented in RTT::base::BufferLockFree< T >, RTT::base::BufferLocked< T >, and RTT::base::BufferUnSync< T >.
|
pure virtual |
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.
Implemented in RTT::base::BufferLockFree< T >, RTT::base::BufferLocked< T >, and RTT::base::BufferUnSync< T >.
|
pure virtual |
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.
Implemented in RTT::base::BufferLockFree< T >, RTT::base::BufferLocked< T >, and RTT::base::BufferUnSync< T >.
|
pure virtual |
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
Implemented in RTT::base::BufferLockFree< T >, RTT::base::BufferLocked< T >, and RTT::base::BufferUnSync< T >.
|
pure virtual |
Write a single value to the buffer.
- Parameters
-
item the value to write
- Returns
- false if the buffer is full.
Implemented in RTT::base::BufferLockFree< T >, RTT::base::BufferLocked< T >, and RTT::base::BufferUnSync< T >.
|
pure virtual |
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())
Implemented in RTT::base::BufferLockFree< T >, RTT::base::BufferLocked< T >, and RTT::base::BufferUnSync< T >.
|
pure virtual |
Releases the pointer
- Parameters
-
item pointer aquired using PopWithoutRelease()
Implemented in RTT::base::BufferLockFree< T >, RTT::base::BufferLocked< T >, and RTT::base::BufferUnSync< T >.
