Constructor Summary public   KeyedObjects2D()      Creates a new instance (initially empty). Method Summary public  void addObject(Object object, Comparable rowKey, Comparable columnKey)      Adds an object to the table. public  Object clone()      Returns a clone. public  boolean equals(Object obj)      Tests this object for equality with an arbitrary object. Parameters:   obj - the object to test (null permitted). public  int getColumnCount()      Returns the column count. public  int getColumnIndex(Comparable key)      Returns the column index for a given key. Parameters:   key - the key. public  Comparable getColumnKey(int column)      Returns the key for a given column. Parameters:   column - the column. public  List getColumnKeys()      Returns the column keys. public  Object getObject(int row, int column)      Returns the object for a given row and column. Parameters:   row - the row index. Parameters:   column - the column index. public  Object getObject(Comparable rowKey, Comparable columnKey)      Returns the object for the given row and column keys. Parameters:   rowKey - the row key. Parameters:   columnKey - the column key. public  int getRowCount()      Returns the row count. public  int getRowIndex(Comparable key)      Returns the row index for a given key. Parameters:   key - the key. public  Comparable getRowKey(int row)      Returns the key for a given row. Parameters:   row - the row index (zero based). public  List getRowKeys()      Returns the row keys. public  int hashCode()      Returns a hashcode for this object. public  void removeColumn(int columnIndex)      Removes a column. public  void removeColumn(Comparable columnKey)      Removes a column. public  void removeObject(Comparable rowKey, Comparable columnKey)      Removes an object. public  void removeRow(int rowIndex)      Removes a row. public  void removeRow(Comparable rowKey)      Removes a row. public  void setObject(Object object, Comparable rowKey, Comparable columnKey)      Adds or updates an object. Constructor Detail KeyedObjects2D public KeyedObjects2D()(Code) Creates a new instance (initially empty). Method Detail addObject public void addObject(Object object, Comparable rowKey, Comparable columnKey)(Code) Adds an object to the table. Performs the same function as setObject(). Parameters:   object - the object. Parameters:   rowKey - the row key. Parameters:   columnKey - the column key. clone public Object clone() throws CloneNotSupportedException(Code) Returns a clone. A clone. throws:   CloneNotSupportedException - this class will not throw this exception, but subclasses (if any) might. equals public boolean equals(Object obj)(Code) Tests this object for equality with an arbitrary object. Parameters:   obj - the object to test (null permitted). A boolean. getColumnCount public int getColumnCount()(Code) Returns the column count. The column count. getColumnIndex public int getColumnIndex(Comparable key)(Code) Returns the column index for a given key. Parameters:   key - the key. The column index. getColumnKey public Comparable getColumnKey(int column)(Code) Returns the key for a given column. Parameters:   column - the column. The key. getColumnKeys public List getColumnKeys()(Code) Returns the column keys. The column keys (never null). getObject public Object getObject(int row, int column)(Code) Returns the object for a given row and column. Parameters:   row - the row index. Parameters:   column - the column index. The object. getObject public Object getObject(Comparable rowKey, Comparable columnKey)(Code) Returns the object for the given row and column keys. Parameters:   rowKey - the row key. Parameters:   columnKey - the column key. The object. getRowCount public int getRowCount()(Code) Returns the row count. The row count. getRowIndex public int getRowIndex(Comparable key)(Code) Returns the row index for a given key. Parameters:   key - the key.
