Method Detail

load

public static Map load(Object[] with)

Load a HashMap from a static array. This allows maps to be created in code.

   Map map = Maps.load( new Object[]
     {
       "keyOne", "valueOne",
       "key2", value2Object,
     }); 
 

Parameters:

with - Array of key/value object pairs to load with

Returns:

map provided for convenience.

load

public static Map load(Map map,
                       Object[] with)

Load a map from a static array. This allows maps to be created in code.

   Map map = Maps.load( new HashMap(), new Object[]
     {
       "keyOne", "valueOne",
       "key2", value2Object,
     }); 
 

Parameters:

map - to load

with - Array of key/value object pairs to load with

Returns:

map provided for convenience.

loadSet

public static Map loadSet(Object[] with)

Load a map as a set from a static array. This allows maps to be initialise. Use containsKey() to find entries as by default they will point to a null item.

   Map map = Maps.loadSet( new Object[]
     { "keyOne", "key2" }); 
 

Parameters:

with - Array of keys to load with

Returns:

map provided for convenience.

loadSet

public static Map loadSet(Map map,
                          Object[] with)

Load a map as a set from a static array. This allows maps to be initialise. Use containsKey() to find entries as by default they will point to a null item.

   Map map = Maps.loadSet( new HashMap(), new Object[]
     { "keyOne", "key2" }); 
 

Parameters:

map - to load

with - Array of keys to load with

Returns:

map provided for convenience.
