Class FieldsInput

java.lang.Object
dev.langchain4j.model.decision.request.FieldsInput
All Implemented Interfaces:
DecisionInput
@Experimental public final class FieldsInput extends Object implements DecisionInput
A DecisionInput made of named fields, for example a support ticket together with the customer's plan: Map.of("ticket", ticket, "plan", "enterprise").

The values can be strings, numbers, booleans, nulls, maps and lists. The value of a field can also be a Content or a list of Contents, for example a named image (Map.of("comment", comment, "photo", ImageContent.from(...))); which kinds of contents are supported depends on the decision model, and decision models must send them as contents (never as JSON text) or throw an UnsupportedFeatureException. Other objects are rejected: convert them to a Map that holds only what the decision needs.

Since:
1.23.0
