Class ObjectFormatter

java.lang.Object
  org.unitils.core.util.ObjectFormatter

public class ObjectFormatter
extends Object

A class for generating a string representation of any object, array or primitive value.

Non-primitive objects are processed recursively so that a string representation of inner objects is also generated. Too avoid too much output, this recursion is limited with a given maximum depth.

Constructor Detail

ObjectFormatter

public ObjectFormatter()

Creates a formatter with a maximum recursion depth of 3.

ObjectFormatter

public ObjectFormatter(int maxDepth,
                       int maxNrArrayOrCollectionElements)

Creates a formatter with the given maximum recursion depth.

NOTE: there is no cycle detection. A large max depth value can cause lots of output in case of a cycle.

Parameters:

maxDepth - The max depth > 0

maxNrArrayOrCollectionElements - The maximum nr of elements for arrays and collections to display > 0

Method Detail

format
