Class AccumulatorAutocorrelationPTensor

java.lang.Object

etomica.data.DataProcessor

etomica.data.DataProcessorForked

etomica.data.DataAccumulator

etomica.modules.glass.AccumulatorAutocorrelationPTensor

All Implemented Interfaces:

DataPipe, DataPipeForked, DataSourceIndependent, IDataSink, IDataSource

public class AccumulatorAutocorrelationPTensor
extends DataAccumulator
implements DataSourceIndependent

Accumulator designed to compute the unnormalized autocorrelation of the pressure tensor components, assuming that off-diagonal components average to 0. All data is saved and processed when requested. The autocorrelation for each component is computed and then averaged together

Constructor Detail

AccumulatorAutocorrelationPTensor

public AccumulatorAutocorrelationPTensor(int nMax,
                                         double dt)

Method Detail

setNMax

public void setNMax(int newNMax)

getNMax

public int getNMax()

getAvgErrFork

public DataFork getAvgErrFork()

addData

protected boolean addData(IData data)

Description copied from class: DataAccumulator

Defined by subclass to specify what this accumulator does when data is added to it.

Specified by:

addData in class DataAccumulator

Parameters:

data - the data to be processed

Returns:

true if the Accumulator's getData method will now return different data.

reset

public void reset()

Description copied from class: DataAccumulator

Clear accumulated values.

Specified by:

reset in class DataAccumulator

getData

public IData getData()

Specified by:

getData in interface IDataSource

Specified by:

getData in class DataAccumulator

Returns:

the data given by this source

processDataInfo

protected IDataInfo processDataInfo(IDataInfo inputDataInfo)

Description copied from class: DataProcessor

Informs this DataProcessor of the DataInfo for the Data it will be processing. Typically the subclass will use this information to make any objects or otherwise prepare for calls to processData.

Specified by:

processDataInfo in class DataProcessor

Parameters:

inputDataInfo - the DataInfo of the Data that will be input to this DataProcessor

Returns:

the DataInfo of the Data that will be output by this DataProcessor

getIndependentData

public DataDoubleArray getIndependentData(int i)

Description copied from interface: DataSourceIndependent

Returns the X data for the given dimension

Specified by:

getIndependentData in interface DataSourceIndependent

getIndependentDataInfo

public DataDoubleArray.DataInfoDoubleArray getIndependentDataInfo(int i)

Description copied from interface: DataSourceIndependent

Returns the DataInfo for the given dimension

Specified by:

getIndependentDataInfo in interface DataSourceIndependent

getIndependentArrayDimension

public int getIndependentArrayDimension()

Description copied from interface: DataSourceIndependent

Returns the number of independent data dimensions

Specified by:

getIndependentArrayDimension in interface DataSourceIndependent

getIndependentTag

public DataTag getIndependentTag()

Description copied from interface: DataSourceIndependent

Returns the tag associated with this DataSource.

Specified by:

getIndependentTag in interface DataSourceIndependent
