@Ram, Ok. The reason why I would prefer to have property as List or Map is
because individual items may contain characters which might overlap with
the element separator.
@Thomas, Can you please point me to or type in an example? I'll try that.
Also, is it suggested to use JSON instead of xml in such cases?
On another note, I was looking into code and ended up with common's
BeanUtils, in which I found a way to set map and list by properties.xml as
well.
Just some special setter method needs to be there.
So in operator, code as be as follows:
private List<String> varList = new ArrayList<>();
private Map<String, String> varMap = new HashMap<>();
public void setVarList(List<String> list) { this.varList = list; }
public void setVarList(int index, String value)
{
for (int i=this.list.size(); i<=index; i++) {
this.varList.add(null);
}
this.varList.set(index, value);
}
public void setVarMap(Map<String, String> map) { this.varMap = map; }
public void setVarMap(String key, String value) { this.varMap.put(key,
value); }
And XML file can contain property as follows:
<property>
<name>dt.operator.randomGenerator.varMap(abc)</name>
<value>123</value>
</property>
<property>
<name>dt.operator.randomGenerator.varMap(pqr)</name>
<value>567</value>
</property>
<property>
<name>dt.operator.randomGenerator.varList[1]</name>
<value>test2</value>
</property>
<property>
<name>dt.operator.randomGenerator.varList[0]</name>
<value>test1</value>
</property>
Can you please suggest if this a fine way for exposing complex operator
properties like map and list?
Thanks,
Chinmay.
