Constructor Detail

HashMapRowMajorDataFrame

public HashMapRowMajorDataFrame(HashMapRowMajorDataFrame.Column<C>... columns)

Method Detail

getColumnClass

public java.lang.Class getColumnClass(C c)

Description copied from interface: DataFrame

Returns the most specific superclass for all cell values in a column

Parameters:

c - the key of the column

Returns:

the common ancestor class of the object values in the column.

getValueAt

public V getValueAt(R row,
                    C column)

Description copied from interface: DataFrame

Returns the value for the cell at the intersection of the column key and row key.

Parameters:

row - the row key whose value is to be queried

column - the column key whose value is to be queried

Returns:

the value Object at the specified cell

setValueAt

public void setValueAt(R row,
                       C column,
                       V value)

Description copied from interface: MutableDataFrame

Sets the value for the cell at the intersection of the column key and row key.

Parameters:

row - the row key whose value is to be changed

column - the column key whose value is to be changed

value - the new value at the specified cell
