Field Detail LIST_ESCAPE final static String LIST_ESCAPE(Code) Constant for the list delimiter escaping character. Method Detail escapeDelimiters public static String escapeDelimiters(String s, char delimiter)(Code) Escapes the delimiters that might be contained in the given string. This method ensures that list delimiter characters that are part of a property's value are correctly escaped when a configuration is saved to a file. Otherwise when loaded again the property will be treated as a list property. Parameters:   s - the string with the value Parameters:   delimiter - the list delimiter to use the correctly esaped string interpolate public static Object interpolate(Object value, AbstractConfiguration config)(Code) Performs interpolation of the specified value. This method checks if the given value contains variables of the form ${...}. If this is the case, all occurrances will be substituted by their current values. Parameters:   value - the value to be interpolated Parameters:   config - the current configuration object the interpolated value split public static List split(String s, char delimiter)(Code) Split a string on the specified delimiter. To be removed when commons-lang has a better replacement available (Tokenizer?). todo: replace with a commons-lang equivalent Parameters:   s - the string to split Parameters:   delimiter - the delimiter a list with the single tokens toBigDecimal public static BigDecimal toBigDecimal(Object value) throws ConversionException(Code) Convert the specified object into a BigDecimal. Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to a BigDecimal toBigInteger public static BigInteger toBigInteger(Object value) throws ConversionException(Code) Convert the specified object into a BigInteger. Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to a BigInteger toBoolean public static Boolean toBoolean(Object value) throws ConversionException(Code) Convert the specified object into a Boolean. Internally the org.apache.commons.lang.BooleanUtils class from the Commons Lang project is used to perform this conversion. This class accepts some more tokens for the boolean value of true, e.g. yes and on. Please refer to the documentation of this class for more details. Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to a boolean toByte public static Byte toByte(Object value) throws ConversionException(Code) Convert the specified object into a Byte. Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to a byte toCalendar public static Calendar toCalendar(Object value, String format) throws ConversionException(Code) Convert the specified object into a Calendar. Parameters:   value - the value to convert Parameters:   format - the DateFormat pattern to parse String values the converted value throws:   ConversionException - thrown if the value cannot be converted to a Calendar toColor public static Color toColor(Object value) throws ConversionException(Code) Convert the specified object into a Color. If the value is a String, the format allowed is (#)?[0-9A-F]{6}([0-9A-F]{2})?. Examples: FF0000 (red) 0000FFA0 (semi transparent blue) #CCCCCC (gray) #00FF00A0 (semi transparent green) Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to a Color toDate public static Date toDate(Object value, String format) throws ConversionException(Code) Convert the specified object into a Date. Parameters:   value - the value to convert Parameters:   format - the DateFormat pattern to parse String values the converted value throws:   ConversionException - thrown if the value cannot be converted to a Calendar toDouble public static Double toDouble(Object value) throws ConversionException(Code) Convert the specified object into a Double. Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to a Double toFloat public static Float toFloat(Object value) throws ConversionException(Code) Convert the specified object into a Float. Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to a Float toInteger public static Integer toInteger(Object value) throws ConversionException(Code) Convert the specified object into an Integer. Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to an integer toIterator public static Iterator toIterator(Object value, char delimiter)(Code) Return an iterator over the simple values of a composite value. The value specified is handled depending on its type: Strings are checked for delimiter characters and splitted if necessary. For collections the single elements are checked. Arrays are treated like collections. All other types are directly inserted. Recursive combinations are supported, e.g. a collection containing array that contain strings. Parameters:   value - the value to "split" Parameters:   delimiter - the delimiter for String values an iterator for accessing the single values toLocale public static Locale toLocale(Object value) throws ConversionException(Code) Convert the specified object into a Locale. Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to a Locale toLong public static Long toLong(Object value) throws ConversionException(Code) Convert the specified object into a Long. Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to a Long toNumber static Number toNumber(Object value, Class targetClass) throws ConversionException(Code) Tries to convert the specified object into a number object. This method is used by the conversion methods for number types. Note that the return value is not in always of the specified target class, but only if a new object has to be created. Parameters:   value - the value to be converted (must not be null) Parameters:   targetClass - the target class of the conversion (must be derivedfrom java.lang.Number) the converted number throws:   ConversionException - if the object cannot be converted toShort public static Short toShort(Object value) throws ConversionException(Code) Convert the specified object into a Short. Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to a short toURL public static URL toURL(Object value) throws ConversionException(Code) Convert the specified object into an URL. Parameters:   value - the value to convert the converted value throws:   ConversionException - thrown if the value cannot be converted to an URL Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
