Method Detail

getColumnClass

public Class getColumnClass(int columnIndex)

inferColumnClass

protected Class inferColumnClass(int columnIndex)

Infers column class from the object in the specified column of the first row. If that cell is empty, this method returns Object.class as the column class.

Parameters:

columnIndex - zero-based index of a table column

Returns:

the class of the object in the specified column of the first row, or Object.class if the cell is empty

isCellEditable

public boolean isCellEditable(int row,
                              int columnIndex)

Determines if the specified cell is editable or not. Returns false if it can determine that the entire specified column is uneditable. Otherwise, it defers the decision to the superclass.

Parameters:

row - zero-based row index

columnIndex - zero-based column index

Returns:

true if the cell is editable; false otherwise

getMetadata

public Object getMetadata()

Temporary placeholder. Integrate with real metadata support.
