Java XMLEncoder Tools
The XMLEncoder class provides a default denotation for JavaBeans in which they are represented as XML documents complying with version 1.0 of the XML specification and the UTF-8 character encoding of the Unicode/ISO 10646 character set.
-
JavaBeans class must have either a public zero-argument constructor.
-
Property must have getter,setter method.
-
If Property have default value or value is null if not modify it will be ignore.
// Example 1:
class Demo {
private String name = "default"; // or private String name = null;
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
}
// Example 2:
class Demo {
// Constructor
public Demo(){
/*
* if name's value have not change or change value is same as default value,
* it will be ignore.
*/
name = "default"; //
}
private String name;
public String getName(){
return name;
}
public void setName(String name){
this.name = name;
}
}-
If Property is static it will be ignore.
-
Not support BigDecimal, it will be ignore.
