Summary

A template is a text containing

• calls with <call> tags.
• variables from EO with $[path].

These active elements will be processed by TemplateCall.

Description	value
super class	CallIO.java
configuration	TemplateConfig.java extends FileConfig.java
json configuration	TemplateConfig.json
methods	execute
config key	templateKey
fixed keys
variable keys	content, loopPath, keep, if, path, mapPath

Test Examples

In the test section there are several examples showing the usage.

Direct Usage

In TemplateCallSimpleTest.executeDirectContent there is a template call with a String.

• create a new TemplateCall with configsCache
• add a String as template via setContent
• execute with an EO.

       final TemplateCall action = new TemplateCall(TestObjectProvider.EO_CONFIGS_CACHE);
        action.setContent("key='$[key]'<call path=\"level0/level1\">level0/level1/key='$[key]'</call>");

        final EO root = TestObjectProvider.create();
        root.add("key").set("value");
        root.add("level0/level1/key").set("value with path");

        final String result = action.execute(root);
        Assert.assertEquals(INFO_COMPARE_FAILS, "key='value'level0/level1/key='value with path'",result);

Test

Template Loading Data

The test TemplateCallSimpleTest show a more complex scenario: The associated template SimpleInsertWithPathAndJson.tpl contain a call reading a json file with key SimpleInsertWithPath.

So it loads at first the json data from SimpleInsertWithPath.json.

Calls With Key

Despite of simple direct java call example, calls are usually predefined by configruation files referenced by a key. This accomplish serializing of the calls e.g. for loading data.

final String result = TestCallsProvider.executeTemplateCall("SimpleInsertWithPathAndJson");
Assert.assertEquals("
key0='test'
Start call: path='level0' --> key0='testOther'  :End call
level0/key0='testOther'",result)

Test

The Template

Here we reference the template 'SimpleInsertWithPath.tpl' by key defined in TemplateConfig.json:

<call execute="JsonCall.read(SimpleInsertWithPath)" />
key0='$[key0]'
Start call: <call path="level0">path='level0' --> key0='$[key0]' </call> :End call
level0/key0='$[level0/key0]'

The Data

The template contains the JsonCall to read SimpleInsertWithPath.json by key defined in JsonConfig.json.

{
  "key0": "test",
  "level0": {
    "key0": "testOther"
  }
}
