ZDictionary

public ZDictionary()

Constructs an empty ZDictionary with the default initial capacity and the default load factor.

ZDictionary

public ZDictionary(Map<String,String> m)

Constructs a new ZDictionary with the same mappings as the specified Map.

Parameters:

m - the specified map.

Method Details

parseParameterList

public static ZDictionary parseParameterList(String parList)

Gets a parameter list string and returns a dictionary object that maps keys to values.

The parameter is a list of pairs key=value concatenated by a semicolon (;). The assignment is optional. The list may contain keys that are not assigned to values, in which case the returned dictionary maps the keys to null.

Parameters:

parList - parameter list in the format "key1=value1;key2=value2;..."

Returns:

a dictionary object that maps keys (converted to lowercase) to values.
