Modify such that accessing an unloaded property throws a LazyInitialisationException. This includes ToMany collections that where previously initialised as empty collections (that didn't lazy load).
This change brings the disableLazyLoad behaviour in line with the unmodifiable behaviour.
It does mean that the use case of bulk mapping from entities to DTOs via something like MapStruct will no longer work nicely (mapping nulls and empty lists versus LazyInitialisationException).
So we can no longer dynamically change the Clock being used and instead for testing purposes need to create the Database with a test clock instance as needed.
Refer to the ExtendedServerTest for an example
- Adds new exceptions UnloadedPropertyException and UnmodifiableEntityException
- Change InterceptReadOnly to use these exception instead of IllegalStateException
- Change collections BeanSet, BeanList, BeanMap from using IllegalStateException to UnsupportedOperationException [to bring these in line with JDK unmodifiable collections]
As HelpScopeTrans isn't in an exported package it's use fails with an error in module path. This adds AOPTransactionScope in the exported package io.ebean.plugin and moves the required methods from SpiEbeanServer to SpiServer to support this move.
This also requires an associate change in ebean-agent to support this feature which will be in ebean-agent 14.9.0.
Although this is ok, makes me think that another option is just to have query.setReadOnly(true)
to mean ... readOnly + disableLazyLoad + error reading unloaded property or collection. As in,
readOnly true without these extra things does not that good [as in the existing readOnly does
not seem very good/safe/useful to use].
Currently, the SELF response type of QueryBuilder returns as Object when really we want it to return the SELF generic type of QueryBuilder, QueryBean, IQueryBean etc
Note that this change requires an updated ebean-agent
Paging is an alternative to specifying the maxRows + firstRow + orderBy on a query.
Example:
```java
var orderBy = OrderBy.of("lastName desc nulls first, firstName asc");
var paging = Paging.of(0, 100, orderBy);
DB.find(Contact.class)
.setPaging(paging)
.where().startsWith("lastName", "foo")
.findList();
```
Changes the query bean code generation for "Associated beans" to have separate AssocOne and AssocMany for *ToOne and *ToMany relationships.
Moves the filterMany() expressions such that they are only available on the *ToMany relationships.
