Returns the type of the object.
Reimplemented from kddml.Core.DataSources.InternalTable. |
|
Saves the object in the system repository. The data schema is representend as XML document. The physical instances as text file in comma separated format. The preprocessing instances as text file in comma separated format. The destination path is provided by the object_path variable for the data schema, by the object_data_path variable for the row data and by the object_PPdata_path variable for the preprocessing instances. By definition, row data and preprocessing information are already stored in the repository.
Reimplemented from kddml.Core.DataSources.InternalTable. |
|
Returns a representation of this object as string.
Reimplemented from kddml.Core.DataSources.InternalTable. |
|
Loads i instances from the position specified by the pointer and returns they as generic object. If the input parameter is greater than the total number of instances, or if it is equal to -1, then the method returns all instances. If i is equal to 0, it returns only the schema of tuples.
Reimplemented from kddml.Core.DataSources.InternalTable. |
|
Increases the instances pointer of the specified quantity.
Reimplemented from kddml.Core.DataSources.InternalTable. |
|
Returns the statistics related to the preprocessing section.
Implements kddml.Core.DataSources.PPInternalTableManager. |
|
Initializes the instances pointer to the begin of data file.
Reimplemented from kddml.Core.DataSources.InternalTable. |
|
Adds the input instances to the table. Throws an exception if the data schema of the input table and the data schema of the input instances are not compatible.
Implements kddml.Core.DataSources.PPInternalTableManager. |
|
Computes the optimal number of instances to load. It can depend from the total number of instances and attributes and the quantity of available system RAM.
Reimplemented from kddml.Core.DataSources.InternalTable. |
|
Returns the history related to this preprocessing table.
Implements kddml.Core.DataSources.PPInternalTableManager. |
|
Sets the history to this preprocessing table.
Implements kddml.Core.DataSources.PPInternalTableManager. |
