#include <gromacs/analysisdata/modules/average.h>
Data module for averaging of columns for each frame.
Output data has the same number of frames as the input data. The number of columns in the output data is the same as the number of data sets in the input data. Each frame in the output contains the average of the column values for each data set in the corresponding frame of the input data.
Multipoint data and missing data points are both supported. The average is always calculated over all data points present in a column for a data set.

|
overridevirtual |
Called (once) when no more data is available.
unspecified | Can throw any exception required by the implementing class to report errors. |
Implements gmx::AnalysisDataModuleSerial.
|
overridevirtual |
Called (once) when the data has been set up properly.
[in] | data | Data object to which the module is added. |
APIError | if the provided data is not compatible. |
unspecified | Can throw any exception required by the implementing class to report errors. |
When the data is ready, either this method or parallelDataStarted() is called, depending on the nature of the input data. If this method is called, the input data will always present the frames in sequential order.
The data to which the module is attached is passed as an argument to provide access to properties of the data for initialization and/or validation. The module can also call AbstractAnalysisData::requestStorage() if needed.
This is the only place where the module gets access to the data; if properties of the data are required later, the module should store them internally. It is guaranteed that the data properties (column count, whether it's multipoint) do not change once this method has been called.
Notice that data
will be a proxy object if the module is added as a column module, not the data object for which AbstractAnalysisData::addColumnModule() was called.
Implements gmx::AnalysisDataModuleSerial.
|
overridevirtual |
Returns properties supported by the module.
The return value of this method should not change after the module has been added to a data (this responsibility can, and in most cases must, be delegated to the user of the module).
The purpose of this method is to remove the need for common checks for data compatibility in the classes that implement the interface. Instead, AbstractAnalysisData performs these checks based on the flags provided.
Does not throw.
Implements gmx::AnalysisDataModuleSerial.
|
overridevirtual |
Returns the total number of frames in the data.
This function returns the number of frames that the object has produced. If requestStorage() has been successfully called, tryGetDataframe() or getDataFrame() can be used to access some or all of these frames.
Does not throw.
Derived classes should implement this to return the number of frames. The frame count should not be incremented before tryGetDataFrameInternal() can return the new frame. The frame count must be incremented before AnalysisDataModuleManager::notifyFrameFinish() is called.
Implements gmx::AbstractAnalysisData.
|
overridevirtual |
Called when a data frame is finished.
[in] | header | Header information for the frame that is ending. |
unspecified | Can throw any exception required by the implementing class to report errors. |
Implements gmx::AnalysisDataModuleSerial.
|
overridevirtual |
Called at the start of each data frame.
[in] | frame | Header information for the frame that is starting. |
unspecified | Can throw any exception required by the implementing class to report errors. |
Implements gmx::AnalysisDataModuleSerial.
|
overridevirtual |
Called one or more times during each data frame.
[in] | points | Set of points added (also provides access to frame-level data). |
APIError | if the provided data is not compatible. |
unspecified | Can throw any exception required by the implementing class to report errors. |
Can be called once or multiple times for a frame. For all data objects currently implemented in the library (and all objects that will use AnalysisDataStorage for internal implementation), it is called exactly once for each frame if the data is not multipoint, but currently this restriction is not enforced.
Implements gmx::AnalysisDataModuleSerial.
