Interface QueryMapper.MapperUpdateFrom

Enclosing interface:

QueryMapper

public static interface QueryMapper.MapperUpdateFrom

Represents the first step in the update query fluent API.

This step defines the entity type to be updated and starts the construction of an update operation. From this point, one or more update assignments must be defined using set(...).to(...) before the operation can 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. Support for update operations depends on the underlying database.

Since:

1.0.0
