Constructor Detail

ObjectRowKey

public ObjectRowKey(java.lang.Object object)

Constructs an ObjectRowKey using the specified object

Parameters:

object - The desired object

Method Detail

getObject

public java.lang.Object getObject()

Returns the object of this ObjectRowKey

Returns:

This ObjectRowKey's object value

equals

public boolean equals(java.lang.Object o)

Standard equals implementation. This method compares the ObjectRowKey object values for equality (== || .equals()). If the passed Object is not an ObjectRowKey instance, the superclass (RowKey) gets a chance to evaluate the Object for equality.

Overrides:

equals in class RowKey

Parameters:

o - the Object to check equality

Returns:

true if equal, false if not

Object.equals(Object)

compareTo

public int compareTo(java.lang.Object o)

Standard implementation of compareTo(Object). This checks for equality first (using equals(Object)), then compares the stored object in the ObjectRowKeys. If the contained object does not implement Comparable, the superclass version of compareTo(Object) is invoked.

Standard implementation of compareTo(Object). This checks for equality first (using equals(Object)), then compares the rowId strings. This should be overridden by RowKey implementations that have a notion of order. This allows for deletions and insertions to be done in reverse order to help ensure the longevity of valid RowKeys.

Specified by:

compareTo in interface java.lang.Comparable

Overrides:

compareTo in class RowKey
