DataBlock

class aixd.data.DataBlock(dobj_list: List[DataObject], name: str | None = None, format_file: str = 'pkl', flag_split_perdim: bool = False, transformation: DataBlockTransformation | None = None, display_name: str | None = None)[source]

Bases: object

Generic block of data, i.e., a concatenation of different instances of data types

Parameters:

dobj_list (List[DataObject]) – A list of data objects.
name (str, optional) – A name for the data block
format_file (str, optional, default=”pkl”) – File format used for storage.
flag_split_perdim (bool, optional, default=False) – Flag to enable the splitting multidimensional DataObject’s
transformation (DataBlockTransformation, optional, default=None) – The per data block normalization.
display_name (str, optional, default=None) – The display name of the data block. If none it’s the same as the name.

Methods

`check_data_consistency`	Checks the data consistency.
`get_cols_dobjs`	In this case, the attributes can be either names of dimensions, or names of full data objects, and we need to return the precise column names that correspond to the attributes.
`get_data_mat`	Returns the data belonging to the requested DataObject's, as a single data matrix.
`get_data_mat_dtypes`	Returns the data types of the columns of the data matrix for the requested DataObject's.
`get_data_mats`	Returns the data belonging to the requested DataObject's, as a list of data matrices.
`get_dobjs`	Returns the data objects.
`info_dobj`	Returns information of all the DataObject's of the DataBlock.
`print_objects`	Prints the names of the DataObject's.
`print_transf`	Prints the applied transformations for the DataBlock.
`read`	Internal function for saving.
`update_obj`	Updates the DataObject instance according to the passed data (e.g., changing its domain or type)
`update_position_indices`	Updates the position and position_index attributes of the DataObject's.
`write`	Internal function for writing.
