WriteH5¶
- class acoular.tprocess.WriteH5¶
Bases:
TimeOut
Saves time signal as *.h5 file.
- source = Instance(SamplesGenerator)¶
Data source;
SamplesGenerator
or derived object.
- name = File(filter=['*.h5'], desc='name of data file')¶
Name of the file to be saved. If none is given, the name will be automatically generated from a time stamp.
- numsamples_write = Int(-1)¶
Number of samples to write to file by result method. defaults to -1 (write as long as source yields data).
- precision = Trait('float32', 'float64', desc='precision of H5 File')¶
The floating-number-precision of entries of H5 File corresponding to numpy dtypes. Default is 32 bit.
- metadata = Dict(desc='metadata to be stored in .h5 file')¶
Metadata to be stored in HDF5 file object
- save()¶
Saves source output to *.h5 file.
- add_metadata(f5h)¶
Adds metadata to .h5 file.
- result(num)¶
Python generator that saves source output to *.h5 file and yields the source output block-wise.
- Parameters:
- numinteger
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. Echos the source output, but reads it from cache when available and prevents unnecassary recalculation.
