About Print Template Classes

You can use a method in a Print Template Class to manipulate the data that a Print Template has available for processing. Here's how it works:

• When a Print Template is processed, it gets its data from the TemplateContext
• That object contains a HashMap for each kind of record that , a data object is simply a HashMap in the . The TemplateContext object is passed to a method in your data-handler so, by manipulating the HashMap(s) it contains, you change the data that the Print Template has available for processing.

• Template reference: $objectName.fieldname
• Retrieve a data object: TemplateContext.get("objectName");
• Add or update a data object: TemplateContext.put("objectName", HashMap);
• Get a field from data object: HashMap.get("fieldName");
• Add or update a field in a data object: HashMap.put("fieldName",value);
  where value is typically a string or a nested HashMap.

__TBD: What are the other standard objects?__

Configuring a Print Template to use a Specified Class and Method

--select the class, and the method to use

Methods that take following arguments are listed:

• com.platform.api.TemplateContext - The container that the print template gets its data from.
• String (objectName) - The name of the object the print template was invoked on.
• String (recordID) - The ID of the record on which it was invoked.

__TBD: TemplateContext is in new javadocs, yes? objectName is passed in, yes? Does return value have to be void?__

Accessing Lookup Target Records

Data from lookup-target records is stored as a nested map. So to get data for the template variable $Order.customer.name:

1. HashMap orderMap = TemplateContext.get("Order") gets the Order HashMap from the context.
2. HashMap customerMap = orderMap.get("customer") gets the lookup-target record for the customer field.
3. String name = customerMap.get("name") gets the customer's name.
