The TagData Class
public class TagData extends java.lang.Object
implements java.lang.Cloneable
This class encapsulates Tag instance attributes and values. Often, this data is fully static in the
case where none of the attributes have runtime expressions as their values. Thus the TagData
class is intended to expose an immutable interface to a set of immutable attribute/value pairs.
This class implements Cloneable , so that implementations can create a static instance and then
just clone it before adding the request-time expressions. The TagData class has two fields and
five methods, described in the following sections.
The attributes Field
private java.util.Hashtable attributes
This field holds a reference to a Hashtable of the tag's attributes.
public static final java.lang.Object REQUEST_TIME_VALUE
This field holds a reference to a distinguished value for an attribute. The value is a request-time
expression, which is not yet available because this TagData instance is being used at
The TagData() Method
public TagData(java.lang.Object[][] atts)
This method is the constructor for a TagData object. It takes a single parameter, a two-
dimensional array of static attributes and values. TagData() returns no value and throws no
