Returns true if the table is a timestamp table with attributes transaction, event and timestamp.
Reimplemented from kddml.Core.DataSources.InternalTable. |
|
Returns the timestamp field position in the data schema.
Implements kddml.Core.DataSources.TimestampInternalTableManager. |
|
Return an enumeration of inited features, i.e. the attribute(s) that must be loaded as item features. Each feature is returned as Weka Attribute object "as is" in table schema.
Implements kddml.Core.DataSources.TimestampInternalTableManager. |
|
Returns the next data sequence in the timestamp table.
Implements kddml.Core.DataSources.TimestampInternalTableManager. |
|
Returns the next data-sequence of the timestamp table, including optional attributes as item features. Before calling this method, some of initFeatures() may be called, otherwise this method return the same result of loadNextDataSequence(). If no optional attribute are present in input table, objects returned by this method are identically to those returned by loadNextDataSequence().
Implements kddml.Core.DataSources.TimestampInternalTableManager. |
|
Returns true if the timestamp table has more data sequences.
Implements kddml.Core.DataSources.TimestampInternalTableManager. |
|
Specify to load all optional attributes from input table.
Implements kddml.Core.DataSources.TimestampInternalTableManager. |
|
Affect optional attributes that will be included as item feature; only numeric optional attributes are included.
Implements kddml.Core.DataSources.TimestampInternalTableManager. |
|
Specify wich optional attributes must be loaded as item features. If "names" is null, then all optional attributes are added, else only attributes in "names" are added. "feature_type" allow to filter attributes by their type (e.g. ALL_FEATURES, NUMERIC_FEATURES, STRING_FEATURES). Note that this method do not raise any exception if no features are recognized. To check which features are processed to be loaded, must use the getInitedFeatures() method.
