Returns the statistics related to this table.
Implemented in kddml.Core.DataSources.InternalTable. |
|
Returns the table dimension in KBytes.
Implemented in kddml.Core.DataSources.InternalTable. |
|
Returns true if the table is a transactional table with attributes transaction and event. Returns false if the table is a relational table.
Implemented in kddml.Core.DataSources.InternalTable, and kddml.Core.DataSources.TransactionalInternalTable. |
|
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 do not coincide.
Implemented in kddml.Core.DataSources.InternalTable. |
|
Tests if there are instances to load.
Implemented in kddml.Core.DataSources.InternalTable. |
|
Initializes the instances pointer to the begin of data file.
Implemented in kddml.Core.DataSources.InternalTable, and kddml.Core.DataSources.PPInternalTable. |
|
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.
Implemented in kddml.Core.DataSources.InternalTable, and kddml.Core.DataSources.PPInternalTable. |
|
Returns the total number of instances.
Implemented in kddml.Core.DataSources.InternalTable. |
|
Returns the total number of attributes.
Implemented in kddml.Core.DataSources.InternalTable. |
|
Returns true if the table is a timestamp table with attributes transaction, event and timestamp.
Implemented in kddml.Core.DataSources.InternalTable, and kddml.Core.DataSources.TimestampInternalTable. |
|
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.
