 org.zkoss.zkmax.xel.util.ExpressionFragment
| ExpressionFragment | | public class ExpressionFragment implements java.io.Serializable(Code) | | Represents an expression fragment of an expression.
When
ExpressionFragment.parse is called, a list of fragments is returned.
Each of them is either a Sring instnce or a
ExpressionFragment instance.
For example, "ab${x + y}cd${z}" is broken into the following
segments, when
ExpressionFragment.parse is called:
String("ab"), ExpressionFragment("x+y"), String("cd") and
ExpressionFragment("z").
It is used to implement
org.zkoss.xel.ExpressionFactory based on an evaluator that doesn't support the syntax of ${expr}.
The users of XEL expressions rarely needs to use this class.
