Method Detail

singletonMap

public static Map<String,Object> singletonMap(String key,
                              Object value)

Helper method that creates a singleton map. Alternative for Collections.singletonMap(), since that method returns a generic typed map depending on the input type, but we often need a map.

map

public static Map<String,Object> map(Object... objects)

Helper method to easily create a map. Takes as input a varargs containing the key1, value1, key2, value2, etc. Note: altough an Object, we will cast the key to String internally.
