    • Method Detail

      • check

        protected void check​(weka.core.Instances data)
        Checks the data.

        Default implementation only checks whether we have any data at all.
        Parameters:
        data - the data to check
      • doFindRows

        protected abstract int[] doFindRows​(weka.core.Instances data)
        Returns the rows of interest in the dataset.
        Parameters:
        data - the dataset to inspect
        Returns:
        the rows of interest
      • findRows

        public int[] findRows​(weka.core.Instances data)
        Returns the rows of interest in the dataset.
        Specified by:
        findRows in interface RowFinder
        Parameters:
        data - the dataset to inspect
        Returns:
        the rows of interest
      • compareTo

        public int compareTo​(Object o)
        Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

        Only compares the commandlines of the two objects.
        Parameters:
        o - the object to be compared.
        Returns:
        a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
        Throws:
        ClassCastException - if the specified object's type prevents it from being compared to this object.
      • equals

        public boolean equals​(Object o)
        Returns whether the two objects are the same.

        Only compares the commandlines of the two objects.
        Overrides:
        equals in class Object
        Parameters:
        o - the object to be compared
        Returns:
        true if the object is the same as this one
      • shallowCopy

        public RowFinder shallowCopy()
        Returns a shallow copy of itself, i.e., based on the commandline options.
        Specified by:
        shallowCopy in interface adams.core.ShallowCopySupporter<RowFinder>
        Returns:
        the shallow copy
      • shallowCopy

        public RowFinder shallowCopy​(boolean expand)
        Returns a shallow copy of itself, i.e., based on the commandline options.
        Specified by:
        shallowCopy in interface adams.core.ShallowCopySupporter<RowFinder>
        Parameters:
        expand - whether to expand variables to their current values
        Returns:
        the shallow copy
      • getRowFinders

        public static String[] getRowFinders()
        Returns a list with classnames of row finders.
        Returns:
        the row finder classnames
