      • WrapperTuple

        public WrapperTuple​(Tuple base)
        Constructor.
        Parameters:
        base - tuple to which all methods are delegated

    • Method Detail

      • getRowIndex

        public long getRowIndex()
        Description copied from interface: Tuple
        Returns the row index for the underlying data set. Note this value may not undergo a simple increment between steps (if rows are excluded from the underlying data set it may increase by more than one in some cases).
        Specified by:
        getRowIndex in interface Tuple
        Returns:
        row index of underlying table row

      • getBooleanValue

        public boolean getBooleanValue​(int icol)
        Description copied from interface: Tuple
        Returns the value of a given column as a boolean. If that element of the table is not of boolean type, the result may not be useful.
        Specified by:
        getBooleanValue in interface Tuple
        Parameters:
        icol - column index
        Returns:
        value of element icol, presumed of boolean type

      • getIntValue

        public int getIntValue​(int icol)
        Description copied from interface: Tuple
        Returns the value of a given column as an integer. If that element of the tuple is not of numeric type, the result may not be useful.
        Specified by:
        getIntValue in interface Tuple
        Parameters:
        icol - column index
        Returns:
        value of element icol, presumed of numeric type

      • getDoubleValue

        public double getDoubleValue​(int icol)
        Description copied from interface: Tuple
        Returns the value of a given column as a double. If that element of the tuple is not of numeric type, the result may not be useful.
        Specified by:
        getDoubleValue in interface Tuple
        Parameters:
        icol - column index
        Returns:
        value of element icol, presumed of numeric type

      • getLongValue

        public long getLongValue​(int icol)
        Description copied from interface: Tuple
        Returns the value of a given column as a long. If that element of the tuple is not of numeric type, the result may not be useful.
        Specified by:
        getLongValue in interface Tuple
        Parameters:
        icol - column index
        Returns:
        value of element icol, presumed of numeric type

      • getObjectValue

        public java.lang.Object getObjectValue​(int icol)
        Description copied from interface: Tuple
        Returns the value of a given column as an object. If that element of the tuple is not of object type, the result may not be useful.

        If the result is a mutable object, its value may be overwritten by subsequent calls to this method (especially following calls to SplittableSequence.next() if this object also implements TupleSequence).

        Specified by:
        getObjectValue in interface Tuple
        Parameters:
        icol - column index
        Returns:
        value of element icol, presumed of object type
