Method Detail

hideCredentials

public static String hideCredentials(Object o)

Hides credentials by replacing them with asterisks. Hides both user and password credentials. Hides credentials specified as properties, as URL query parameters, or as URL user info.

Parameters:

o - the object with credentials in string representation

Returns:

the string representation with hidden credentials

deepToString

public static String deepToString(Object object)

Returns a compact string representation of the "deep contents" of the specified object. If the object is array or collection or map and it contains other arrays as elements, the string representation contains their contents and so on. This method is designed for converting multidimensional arrays to strings.

This method always prints at least 10 elements in a collection, map, or array and truncates the string representation of object at 120 characters.

Parameters:

object - the object whose string representation to return

Returns:

a compact string representation of the "deep contents" of the specified object.

printMap

public static String printMap(Map<?,?> map)

Returns a compact string representation of the "deep contents" of the specified Map. If the map contains other arrays or maps or collections as elements, the string representation contains their contents and so on. This method is designed for converting multidimensional map to strings.

This method always prints at least 10 elements in a map and truncates the string representation of object at 120 characters.

Parameters:

map - the map whose string representation to return

Returns:

a compact string representation of the "deep contents" of the specified map.

printCollection

public static String printCollection(Collection<?> collection)

Returns a compact string representation of the "deep contents" of the specified collection. If the collection contains other arrays or maps or collections as elements, the string representation contains their contents and so on. This method is designed for converting multidimensional collection to strings.

This method always prints at least 10 elements in a collection and truncates the string representation of object at 120 characters.

Parameters:

collection - the collection whose string representation to return

Returns:

a compact string representation of the "deep contents" of the specified collection.

printArray

public static String printArray(Object[] objects)

Returns a compact string representation of the "deep contents" of the specified array. If the array contains other arrays as elements, the string representation contains their contents and so on. This method is designed for converting multidimensional arrays to strings.

This method always prints at least 10 elements in an array and truncates the string representation of object at 120 characters.
