Method Detail

getValidEnums

public E[] getValidEnums()

getValidEnumsString

public java.lang.String getValidEnumsString()

isValid

public boolean isValid(java.lang.Object obj,
                       StringHolder errMsg)

Description copied from class: RangeBase

Returns true if the specified object is valid for this Range, and false otherwise. If the object is not valid, and errMsg is not null, then errMsg.value should be set to a message describing why the object is not valid.

Specified by:

isValid in interface Range

Specified by:

isValid in class RangeBase

Parameters:

obj - Object to be testes

errMsg - Optional handle for storing error message

Returns:

true if the object is valid

scan

public void scan(ReaderTokenizer rtok,
                 java.lang.Object ref)
          throws java.io.IOException

Scans this element from a ReaderTokenizer. The expected text format is assumed to be compatible with that produced by write.

Specified by:

scan in interface Scannable

Overrides:

scan in class RangeBase

Parameters:

rtok - Tokenizer from which to scan the element

ref - optional reference object which can be used for resolving references to other objects

Throws:

java.io.IOException - if an I/O or formatting error occured

write

public void write(java.io.PrintWriter pw,
                  NumberFormat fmt,
                  java.lang.Object ref)
           throws java.io.IOException

Writes a text description of this element to a PrintWriter. The text description should be compatable with scan and complete enough to allow full reconstruction of the element.

Specified by:

write in interface Scannable

Overrides:

write in class RangeBase

Parameters:

pw - stream for writing the element

fmt - numeric formating information

ref - optional reference object which can be used for producing references to other objects

Throws:

java.io.IOException - if an I/O error occured

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

main

public static void main(java.lang.String[] args)
