  • Method Details

    • getMaxLocalProjDBSize

      long getMaxLocalProjDBSize()
    • getMaxPatternLength

      int getMaxPatternLength()
    • getMinSupport

      double getMinSupport()
    • getSequenceCol

      String getSequenceCol()
    • maxLocalProjDBSize

      LongParam maxLocalProjDBSize()
      Param for the maximum number of items (including delimiters used in the internal storage format) allowed in a projected database before local processing (default: 32000000). If a projected database exceeds this size, another iteration of distributed prefix growth is run.
      Returns:
      (undocumented)
    • maxPatternLength

      IntParam maxPatternLength()
      Param for the maximal pattern length (default: 10).
      Returns:
      (undocumented)
    • minSupport

      DoubleParam minSupport()
      Param for the minimal support level (default: 0.1). Sequential patterns that appear more than (minSupport * size-of-the-dataset) times are identified as frequent sequential patterns.
      Returns:
      (undocumented)
    • sequenceCol

      Param<String> sequenceCol()
      Param for the name of the sequence column in dataset (default "sequence"), rows with nulls in this column are ignored.
      Returns:
      (undocumented)
