asMap

public static Map<String,String> asMap(String string)

Read a Map from string. The string is a ";" separated key/value list.
Example

 a=b;foo.bar=gnu
 

The values are plain literals or quoted strings (@see ReaderTools.readEntry(Reader, char). The resulting map is "flat" (not nested), even with "." separated keys.

 string ::= entry [ ';' entry ]*
 entry ::= key [ '=' value ]
 key ::= id [ '.' id ]
 

Parameters:

string -

Returns:

The parsed Map

asMapBoolean

public static Map<String,Boolean> asMapBoolean(String string)

public static String asString(String str,
              String defaultValue)

asStringArray

asThreeState

public static Boolean asThreeState(String booleanString)
                            throws ConverterException

Throws:

ConverterException

asThreeState

public static Boolean asThreeState(String booleanString,
                   Boolean defaultValue)
