Class WrapperTuple

Method Details

• 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 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 TupleSequence.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
