TimeSamples¶

class acoular.sources.TimeSamples¶

Bases: acoular.tprocess.SamplesGenerator

Container for time data in *.h5 format.

This class loads measured data from h5 files and and provides information about this data. It also serves as an interface where the data can be accessed (e.g. for use in a block chain) via the result() generator.

name = File(filter=['*.h5'], …¶

Full name of the .h5 file with data.

basename = Property( depends_on = 'name', #filter=['*.h5'], …¶

Basename of the .h5 file with data, is set automatically.

calib = Trait( Calib, …¶

Calibration data, instance of Calib class, optional .

numchannels = CLong(0, …¶

Number of channels, is set automatically / read from file.

numsamples = CLong(0, …¶

Number of time data samples, is set automatically / read from file.

data = Any( transient = True, …¶

The time data as array of floats with dimension (numsamples, numchannels).

h5f = Instance(H5FileBase, transient = True)¶

HDF5 file object

metadata = Dict( …¶

Provides metadata stored in HDF5 file object

load_data()¶

Open the .h5 file and set attributes.

load_timedata()¶

loads timedata from .h5 file. Only for internal use.

load_metadata()¶

loads metadata from .h5 file. Only for internal use.

result(num=128)¶

Python generator that yields the output block-wise.

Parameters

numinteger, defaults to 128

This parameter defines the size of the blocks to be yielded (i.e. the number of samples per block) .

Returns

Samples in blocks of shape (num, numchannels).

The last block may be shorter than num.
