pybdy.reader package
Submodules
pybdy.reader.directory module
Abstraction for the data repository.
@author: Mr. Srikanth Nagella.
class pybdy.reader.directory.GridGroup
Bases:
object
method __init__()
method get_meta_data(variable, source_dic)
Return a dictionary with meta data information correspoinding to the variable.
class pybdy.reader.directory.Reader(directory, time_adjust)
Bases:
object
Reader for all the files in the directory as one single object.
Examples
reader = Reader(“Folder path”)
reader[“t”][“votemper”][:, :, :, :]
method __init__(directory, time_adjust)
Take in directory path as input and return the required information to the bdy.
Parameters
directory : The directory in which to look for the files
time_adjust : amount of time to be adjusted to the time read from file.Returns
None : object
method calculate_time_interval()
Calculate the time interval of the each grid.
If all the grids get the same interval then it sets it to the days and hours. Otherwise it throws an error.
method delta_time_interval(time1, time2)
Get the difference between the two times in days and hours.
method get_dir_list(grid)
Scan the directory for a input grid related NetCDF files (i.e., ending with the grid name.
Parameters
grid (str) : grid name eg. ‘t’,’v’,’u’,’i’.
Returns
dir_list (list) : list of files
method get_source_timedata(grid, t_adjust)
Get the source time data information.
Builds up sourcedata objects of a given grid.
method grid_type_list = ['t', 'u', 'v', 'i']
class pybdy.reader.directory.Variable(filenames, variable)
Bases:
object
method __init__(filenames, variable)
method get_attribute_values(attr_name)
Return the attribute value of the variable.
method get_dimensions()
Return the dimensions of the variables.
method set_time_dimension_index()
Set the time dimension index.
method time_counter_const = 'time_counter'
pybdy.reader.factory module
Generic file loader factory.
@author: Mr. Srikanth Nagella
pybdy.reader.factory.GetFile(uri)
pybdy.reader.factory.GetReader(uri, t_adjust, reader_type=None)
class pybdy.reader.factory.NetCDFFile(filename)
Bases:
object
method __init__(filename)
method close()
pybdy.reader.ncml module
NcML reading implementation using pyjnius.
@author: Mr. Srikanth Nagella.
class pybdy.reader.ncml.GridGroup(filename, dataset)
Bases:
object
Class that provides an indirection to the grid type.
Since ncml file has aggregation of all the variables this is just a place holder.
method __init__(filename, dataset)
Source data that holds the dataset information.
method get_meta_data(variable, source_dic)
Return a dictionary with meta data information correspoinding to the variable.
method logger = \
method update_atrributes()
Update the units and calendar information for the grid.
class pybdy.reader.ncml.NcMLFile(filename)
Bases:
object
method __init__(filename)
method close()
class pybdy.reader.ncml.Reader(uri, time_adjust)
Bases:
object
High level object for the NCML reader, from here using grid type will return the grid data.
Examples
reader = Reader(“NCML Filename”)
reader[“t”][“votemper”][:, :, :, :]
method __init__(uri, time_adjust)
method close()
Not yet implemented.
method grid_type_list = ['t', 'u', 'v', 'i']
method time_counter = 'time_counter'
class pybdy.reader.ncml.Variable(dataset, variable)
Bases:
object
method __init__(dataset, variable)
method get_attribute_value(attr_name)
Return the attribute value of the variable.
