This section provides information about the way the ATG REST Web Services server expects to receive parameter values.
Using Primitive Values in Input
Format primitive values as shown in the following table.
Value Type | Values Accepted |
|---|---|
| A sequence of characters. For example, “MyUsername.” |
| An integer or decimal number. For example, “123” or “123.456.” |
|
|
Using Multiple Values in Input
The ATG REST Web Services server will accept map and collection input when you set the values of properties that accept multiple values.
Unless you are setting the value of a repository item, you must specify the Java classes used for the container and the contents.
When you set the value of a non-repository, Nucleus component property, the Legacy REST Web Services server will replace all values with any new values that you set. To append a value to an existing collection, you must supply all the existing values along with the new values.
You can configure the way the ATG REST Web Services server appends or replaces multiple values in a repository item property.
Specifying Java Classes for Multiple Value Input
Specify the Java classes for your array, collection, and map values as shown in the following table.
Value Type | Format |
|---|---|
| <array-element-class>:[value1,value2,...,valueN] For example:
|
| <collection-container-class>:<element-class>:[value1,value2,...,valueN] For example:
|
| <map-class>:<key-class>:<value-class>:[key1=value1,key2=value2,key3=value3] For example:
|
If your input is in JSON format, you can use the atg-rest-param-class-types control parameter to specify Java classes. The atg-rest-param-class-types parameter includes two components, container-class and element-class. Include this attribute in your JSON input as shown below.
{'atg-rest-param-class-types':{'container-class':
'java.util.ArrayList','element-class':
'java.lang.String'},'arg1':['sit','stay','speak']}See information about the atg-rest-param-class-types parameter in the Adding Control Parameters section.
Legacy REST servers are configured to append values to repository item properties using the atg-rest-append-multi-values control parameter. For information this parameter, refer to the Multiple Values in Input section.
Using Object Values in Input
To set a property that takes a Java object as its value, include the atg-rest-class-type control parameter along with the initial properties for the object in the positional parameter for the property value. The atg-rest-class-type control parameter specifies the Java class of the object. Use either JSON or XML to enclose the positional parameter.
The ATG REST Web Services server will return a boolean value to indicate whether the object property has been set successfully. If it is set successfully, the returned value is true.
Note: The Legacy REST Web Services interface can only create objects of classes that have a null constructor. At least one constructor for the class must have no arguments.
The following is an object property value encoded in JSON. The class for the object is atg.MyObjectValue. The following parameters set properties of the new object.
{"arg1":
{"atg-rest-class-type" : "atg.MyObjectValue",
{"atg-rest-values": {
"name" : "Berthoud",
"height" : "1"}
}Here is the same object property value, encoded in XML.
<parameters>
<arg1>
<atg-rest-class-type>atg.MyObjectValue</atg-rest-class-type>
<atg-rest-values>
<name>Berthoud</name>
<height>1</height>
</arg1>
</parameters>
The following example shows a POST request to set an object property value for a Nucleus component.
$ curl -v -b cookies.txt -X POST -H "Content-Type: application/json" –d
"{"arg1":{"atg-rest-class-type":"atg.MyObjectValue",
"name":"Berthoud","height":"1"}}"

{"atgResponse": true}Using Nested Multiple Value Objects in Input
To set a property value that takes a Java object that holds other Java objects, use the atg-rest-class-descriptor control parameter to specify the Java class of the nested objects. For example, if you are setting a property value that takes a List of Sets, indicate the Java class of the Set using the atg-rest-class-descriptor parameter. Then include the values for the nested Sets.
The name of the parameter inside the atg-rest-class-descriptor matches the name of one of the actual values that you supply later in the input parameter.
The input structure for nested multiple value objects builds on the structure for input objects in general.
The following example uses the atg-rest-class-descriptor control parameter to specify that the value of the myListOfSets property is a java.util.ArrayList object. That ArrayList object holds java.util.HashSet objects. After the atg-rest-class-descriptor, the example provides the values that are nested inside the myListOfSets property.
{arg1 : {
"atg-rest-class-type":"foo.class.WithNestedMultis",
"atg-rest-class-descriptor": {
"myListOfSets": {
"container-class": "java.util.ArrayList",
"element-class": "java.util.HashSet"
}
},
"myListOfSets": [["red","blue"],["green","yellow"]]
}
}Here is the same object property value, encoded in XML.
<arg1> <atg-rest-class-type>foo.class.WithNestedMultis</atg-rest-class-type> <atg-rest-class-descriptor> <myListOfSets> <container-class>java.util.ArrayList</container-class> <element-class>java.util.HashSet</element-class> </myListOfSets> </atg-rest-class-descriptor> <myListOfSets> <element> <element>red</element> <element>blue</element> </element> <element> <element>green</element> <element>yellow</element> </element> </myListOfSets> </arg1>
Using Three or More Nested Levels
Include additional container-class and element-class parameters for each nested level of multiple value objects. The element-class parameter of the parent object holds the additional container-class and element-class parameters.
For example:
"atg-rest-class-descriptor": {
"myListOfSets": {
"container-class": "java.util.ArrayList",
"element-class": {
"container-class": "java.util.HashSet",
"element-class": "java.util.HashMap"
}
}
}Using Array Types
To specify an array type in the atg-rest-class-descriptor control parameter, use the standard Java notation for arrays.
Array Type | Java Notation |
|---|---|
|
|
|
|
|
|
Two-dimensional array of |
|
Using Key Class Types for Map Values
Keys for Map object values must be Strings. No other class types are supported.
Adding Date Format in Input
Use the following date format when sending dates to the Legacy REST Web Services interface.
MM/dd/yyyy HH:mm:ss z
For example, 01/29/2015 14:45:11 PDT
Setting Properties to Null
Use the atg-rest-null parameter to set the value of a component or repository item property to null. Set the property and include this parameter as the new value.
The following example sets the value of a component property to null.
$ curl -v -b cookies.txt -X POST \
-H "Content-Type: application/json" \
-d "{"arg1":"atg-rest-null"}" \
