Method Details

setMapInt

public static void setMapInt(Map map,
 String key,
 int val)

getMapInt

public static int getMapInt(Map map,
 String key,
 int def)

getMapLong

public static long getMapLong(Map map,
 String key,
 long def)

getMapString

public static String getMapString(Map map,
 String key,
 String def)

Retrieves a string value from the map, parsing byte arrays if needed. If the map is invalid, the key does not exist, or if the value is null, def is returned.

getMapStringArray

public static String[] getMapStringArray(Map map,
 String key,
 String[] def)

getString

public static String getString(Object obj)

setMapString

public static void setMapString(Map map,
 String key,
 String val)

Puts a String value into a map as a UTF-8 byte array. If value is null, removed key from map

getMapByteArray

public static byte[] getMapByteArray(Map map,
 String key,
 byte[] def)

getMapObject

public static Object getMapObject(Map map,
 String key,
 Object def,
