Constructor Index

o NoStringConstraints()
Constructor for an empty string constraint.

Method Index

o convert(String)
Returns the string itself.
o isSatisfied(String)
Returns always true because any string satisfies the empty constraint.
o myStreamSize()
Returns the size of the stream that would hold the externalized form of these constraints.
o readObject(StreamInputInterface)
Internalizes this Constraint.
o showInfo(Frame, String)
Does nothing because every string is allowed.
o writeObject(StreamOutputInterface)
Externalizes this Constraint.

Constructors

o NoStringConstraints 
  public NoStringConstraints()
Constructor for an empty string constraint.
Returns:
the new no-constraint constraint object.

Integer

Methods

o isSatisfied 
  public boolean isSatisfied(String s)
Returns always true because any string satisfies the empty constraint.
Parameters:
s - the string to test.
Returns:
true.
o convert 
  public Object convert(String s) throws StringConversionException
Returns the string itself.
Parameters:
s - is the string to convert.
Returns:
the the string.
Throws: StringConversionException
if the string could not be converted.
o showInfo 
  public void showInfo(Frame frame,
                       String fieldName)
Does nothing because every string is allowed.
Parameters:
frame - is the parent frame.
Returns:
none.
o myStreamSize 
  public int myStreamSize() throws StreamIOException
Returns the size of the stream that would hold the externalized form of these constraints.
Returns:
the size of the stream in bytes

Streamable
o readObject 
  public void readObject(StreamInputInterface stream) throws StreamIOException
Internalizes this Constraint. In fact does nothing since an empty constraint needs not to be read.
Parameters:
stream - is the stream of data the object state is retrieved from
Returns:
none.
See Also:
Streamable
o writeObject 
  public void writeObject(StreamOutputInterface stream) throws StreamIOException
Externalizes this Constraint. In fact does nothing since an empty constraint does not need to be stored.
Parameters:
stream - is the stream of data the object state is recorded in
Returns:
none
