ObjectUtility

private ObjectUtility(boolean useToString,
 boolean isIndenting,
 int initialLevel,
 int increment)

Method Details

make

public static ObjectUtility make(boolean useToString,
 boolean isIndenting,
 int initialLevel,
 int increment)

Construct an Utility instance with the desired objectToString behavior.

make

public static ObjectUtility make(boolean useToString,
 boolean isIndenting)

Construct an Utility instance with the desired objectToString behavior.

make

public static ObjectUtility make()

Get the standard Utility object that supports objectToString with indented display and no use of toString() methods.

defaultObjectToString

public static String defaultObjectToString(Object object)

A convenience method that gives the default behavior: use indenting to display the object's structure and do not use built-in toString methods.

compactObjectToString

public static String compactObjectToString(Object object)

objectToString

public String objectToString(Object obj)

objectToString handles display of arbitrary objects. It correctly handles objects whose elements form an arbitrary graph. It uses reflection to display the contents of any kind of object. An object's toString() method may optionally be used, but the default is to ignore all toString() methods except for those defined for primitive types, primitive type wrappers, and strings.

equals

public static boolean equals(Object obj1,
 Object obj2)

concatenateArrays

public static Object concatenateArrays(Object arr1,
 Object arr2)

If arr1 and arr2 are both arrays of the same component type, return an array of that component type that consists of the elements of arr1 followed by the elements of arr2. Throws IllegalArgumentException otherwise.

private void objectToStringHelper(IdentityHashMap printed,
 ObjectWriter result,
 Object obj)

mustUseToString
