Interface QueryMapper.MapperUpdateSetStep

All Superinterfaces:
QueryMapper.MapperUpdateQueryBuild
Enclosing interface:
QueryMapper
public static interface QueryMapper.MapperUpdateSetStep extends QueryMapper.MapperUpdateQueryBuild
Represents the update assignment step of the fluent update API.

This step allows defining one or more field assignments for an update operation. From this point, additional assignments may be added, the update scope may be restricted using where(...), or the operation may be executed. 

@Inject
Template template;

template.update(Book.class)
    .set("title").to("Domain-Driven Design with Java")
    .set("publishedYear").to(2025)
    .where("author").eq("Ada")
    .execute();
The returned instance is mutable and not thread-safe.
