public class DiffResult extends Object implements Iterable<Diff<?>>
A DiffResult contains a collection of the differences between two
Diffable objects. Typically these differences are displayed using
toString() method, which returns a string describing the fields that
differ between the objects.
Use a DiffBuilder to build a DiffResult comparing two objects.
| Modifier and Type | Field and Description |

The
String returned when the objects have no differences:

| Modifier and Type | Method and Description |
|---|---|
List<Diff<?>> |
getDiffs()
Returns an unmodifiable list of
Diffs. |
int |
getNumberOfDiffs()
Returns the number of differences between the two objects.
|
ToStringStyle |
getToStringStyle()
Returns the style used by the
toString() method. |
Iterator<Diff<?>> |
iterator()
Returns an iterator over the
Diff objects contained in this list. |

Builds a
String description of the differences contained within
this DiffResult. |

toString(ToStringStyle style)
Builds a
String description of the differences contained within
this DiffResult, using the supplied ToStringStyle. |

The String returned when the objects have no differences:

public List<Diff<?>> getDiffs()
Returns an unmodifiable list of Diffs. The list may be empty if
there were no differences between the objects.
Diffspublic int getNumberOfDiffs()
Returns the number of differences between the two objects.
public ToStringStyle getToStringStyle()
Returns the style used by the toString() method.
public String toString()
Builds a String description of the differences contained within
this DiffResult. A ToStringBuilder is used for each object
and the style of the output is governed by the ToStringStyle
passed to the constructor.
If there are no differences stored in this list, the method will return
OBJECTS_SAME_STRING. Otherwise, using the example given in
Diffable and ToStringStyle.SHORT_PREFIX_STYLE, an output
might be:
Person[name=John Doe,age=32] differs from Person[name=Joe Bloggs,age=26]
This indicates that the objects differ in name and age, but not in smoking status.
To use a different ToStringStyle for an instance of this class,
use toString(ToStringStyle).
public String toString(ToStringStyle style)
Builds a String description of the differences contained within
this DiffResult, using the supplied ToStringStyle.
