Constructor Summary

GenericBeanDiffer()

Method Summary

boolean	diff(java.lang.Object a, java.lang.Object b, ResultSet r, DiffContext c) If the objects being diffed are beans this method returns true - i.e.
protected ResultSet	diffProperty(java.lang.Object a, java.lang.Object b, ResultSet r, DiffContext c, PropertyInfo prop) Three types of property are supported 1) those that convert to strings - convert to strings and compare 2) array properties - diff them with the engine as lists 3) other objects - let the diff engine decide what to do with them
protected boolean	ignoreProperty(PropertyInfo prop) Ignores the given property.

diff

public boolean diff(java.lang.Object a,
                    java.lang.Object b,
                    ResultSet r,
                    DiffContext c)

If the objects being diffed are beans this method returns true - i.e. we diffed. If a or b are null no diffing is actually done, the result set is just marked as not the same.

diff in interface Differ

Returns:

true if the diff operation has been performed by this Differ.

diffProperty

protected ResultSet diffProperty(java.lang.Object a,
                                 java.lang.Object b,
                                 ResultSet r,
                                 DiffContext c,
                                 PropertyInfo prop)

Three types of property are supported
1) those that convert to strings - convert to strings and compare
2) array properties - diff them with the engine as lists
3) other objects - let the diff engine decide what to do with them

ignoreProperty

protected boolean ignoreProperty(PropertyInfo prop)

Ignores the given property. Override to provide different implementation.
