Returns the next data sequence of the timestamp table.
Implemented in kddml.Core.DataSources.TimestampInternalTable. |
|
Returns the next data-sequence of the timestamp table, including optional attributes as item features. Before calling this method, some of iniFeatures() 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().
Implemented in kddml.Core.DataSources.TimestampInternalTable. |
|
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.
Implemented in kddml.Core.DataSources.TimestampInternalTable. |
|
Specify to load all optional attributes from input table.
Implemented in kddml.Core.DataSources.TimestampInternalTable. |
|
Affect optional attributes that will be included as item feature; only numeric optional attributes are included.
Implemented in kddml.Core.DataSources.TimestampInternalTable. |
|
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.

Returns true if the timestamp table has more data sequences.
Implemented in kddml.Core.DataSources.TimestampInternalTable. |
|
Returns the timestamp field position in the data schema.

|
Load all optional attributes in table as item features |
|
Load all numeric attributes in table as item features |
|
Load all non numeric attributes in table as item features |
