Property expression parsing

  The parsing of property value expressions is handled by two
  closely related classes: org.apache.fop.fo.expr.PropertyTokenizer
  and its subclass, org.apache.fop.fo.expr.PropertyParser,
  and by refineParsing(int, FONode,
  PropertyValue) methods in the individual property
  classes.  PropertyTokenizer, as
  the name suggests, handles the tokenizing of the expression,
  handing tokens back to
  its subclass, PropertyParser. PropertyParser, in turn, returns a PropertyValueList, a list of PropertyValues.


  The tokenizer and parser rely in turn on the datatype
  definitions from the org.apache.fop.datatypes package,
  which include the PropertyValue datatype constant definitions.


Data types

  The data types currently defined in
  org.apache.fop.datatypes include:


  

  Numbers and lengths



  Numeric
  
The fundamental length data type.  Numerics of
various types are constructed by the classes listed
below.
  



  
  Constructor classes for Numeric



  
  Ems
  Relative length in ems



  
  IntegerType
  



  
  Length
  In centimetres(cm), millimetres(mm),
inches(in), points(pt), picas(pc) or pixels(px)



  
  Percentage
  

  

  Other Numeric
  
Other numeric vaues which do not interact with the
lengths represented by Numeric values.
  



  
  Angle
  In degrees(deg), gradients(grad) or
radians(rad)



  
  Frequency
  In hertz(Hz) or kilohertz(kHz)



  
  Time
  In seconds(s) or milliseconds(ms)



  Strings



  StringType
  
Base class for data types which result in a String.
  



  
  Literal
  
A subclass of StringType for literals which
exceed the constraints of an NCName.
  



  
  MimeType
  
A subclass of StringType for literals which
represent a mime type.
  



  
  UriType
  
A subclass of StringType for literals which
represent a URI, as specified by the argument to
url().
  



  
  NCName
  
A subclass of StringType for literals which
meet the constraints of an NCName.
  



  
  
  Country
  An RFC 3066/ISO 3166
