ExpressionFragment (zk 10.0.0 API)

java.lang.Object
- org.zkoss.zkmax.xel.util.ExpressionFragment

All Implemented Interfaces:

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

3.0.0

    String("ab"), ExpressionFragment("x+y"), String("cd") and ExpressionFragment("z").
    
    Parameters:
    
    expr - the expression that may or may not contain one or multiple ${expr}. It cannot be null.
