public abstract class Expression
extends java.lang.Object
implements java.io.Serializable, java.lang.Cloneable
Purpose: Define an object-level representation of a database query where clause.
Description: An expression is a tree-like structure that defines the selection criteria for a query against objects in the database. The expression has the advantage over SQL by being at the object-level, i.e. the object model attributes and relationships can be used to be query on instead of the database field names. Because it is an object, not a string the expression has the advantage that is can be easily manipulated through code to easily build complex selection criterias.

allOf is the universal counterpart to the existential anyOf. To have the condition evaluated for each instance it must be put inside of a subquery, which can be expressed as not exists (any of attributeName some condition). (All x such that y = !Exist x such that !y).
Likewise the syntax employee.allOf("phoneNumbers").get("areaCode").equal("613") is not supported for the

This method saves you from writing the sub query yourself. The above is equivalent to the following expression:
ExpressionBuilder employee = new ExpressionBuilder();
ExpressionBuilder phone = new ExpressionBuilder();
ReportQuery subQuery = new ReportQuery(Phone.class, phone);
subQuery.retreivePrimaryKeys();
subQuery.setSelectionCriteria(phone.equal(employee.anyOf("phoneNumbers").and(
phone.get("areaCode").notEqual("613")));
Expression exp = employee.notExists(subQuery);
Note if employee has no phone numbers allOf ~ noneOf.

Set an as of clause at the expression level to still query for current objects while expressing selection criteria like:
Simultaneously querying on two versions of the same object (one past one present) lets you express these advanced selection criteria.
Example: Querying on past attributes using parallel expressions.
// Finds all employees who lived in Ottawa as of a past time.
ExpressionBuilder employee = new ExpressionBuilder();
ExpressionBuilder pastEmployee = new ExpressionBuilder(Employee.class);
pastEmployee.asOf(pastTime);
Expression pastAddress = pastEmployee.get("address"); // by default address will also be as of past time.
Expression selectionCriteria = pastAddress.get("city").equal("Ottawa").and(
employee.equal(pastEmployee));
The advantage of the parallel expression is that you can still read current objects, the as of clause will affect only the where clause / selection criteria.
You may be tempted to rewrite the above as employee.get("address").asOf(pastTime). That is allowed but see below for the finer points involved in this.
Example: Querying on object changes using parallel expressions.
// Finds all employees who recently received a raise. Note that current
// objects are returned, so can be cached normally.
ExpressionBuilder employee = new ExpressionBuilder();
Expression pastEmployee = new ExpressionBuilder(Employee.class);
pastEmployee.asOf(yesterday);
Expression parallelJoin = employee.equal(pastEmployee);
Expression selectionCriteria = parallelJoin.and(
employee.get("salary").greaterThan(pastEmployee.get("salary")));
Example: Querying on object changes using custom query keys
// First define the custom query key and add it to your descriptor.
ExpressionBuilder builder = new ExpressionBuilder(Employee.class);
Expression joinCriteria = builder.getField("EMPLOYEE.EMP_ID").equal(builder.getParameter("EMPLOYEE.EMP_ID"));
OneToOneQueryKey selfReferential = new OneToOneQueryKey();
selfReferential.setName("this");
selfReferential.setJoinCriteria(joinCriteria);
selfReferential.setReferenceClass(Employee.class);
getSession().getDescriptor(Employee.class).addQueryKey(selfReferential);
// Now build query as before.
Expression employee = new ExpessionBuilder();
Expression pastEmployee = employee.get("this").asOf(yesterday);
Expression selectionCriteria = employee.get("salary").greaterThan(pastEmployee.get("salary"));
Note in general that any parallel expression can be rewritten using a custom query key. EclipseLink will even automatically interpret x.get("this") for you so you do not need to define the above query key first.
Full Reference:
If an object is mapped to multiple tables, then each table will be as of the same time. Two objects mapped to the same table can not have different as of times. Conversely only expressions which have associated tables can have an as of clause.
If an as of clause is not explicitly set an expression will use the clause of its base expression, and so on recursively until one is found or an ExpressionBuilder is reached. Some usage scenarios follow:
Watch out for x.asOf(oneTime).get("y").asOf(anotherTime).

Java: NA
SQL: NEW_TIME(date, 'EST', 'PST')
public Expression nextDay(java.lang.Object dayName)
public Expression noneOf(java.lang.String attributeName, Expression criteria)
attributeName
holding true for criteria.
For every expression with an anyOf, its negation has either an allOf or a noneOf. The following two examples will illustrate as the second is the negation of the first:
AnyOf Example: Employees with a '613' area code phone number.
ReadAllQuery query = new ReadAllQuery(Employee.class);
ExpressionBuilder employee = new ExpressionBuilder();
Expression exp = employee.anyOf("phoneNumbers").get("areaCode").equal("613");
NoneOf Example: Employees with no '613' area code phone numbers.
ExpressionBuilder employee = new ExpressionBuilder();
ExpressionBuilder phones = new ExpressionBuilder();
Expression exp = employee.noneOf("phoneNumbers", phones.get("areaCode").equal("613"));
SQL:
SELECT ... EMPLOYEE t0 WHERE NOT EXISTS (SELECT ... PHONE t1 WHERE
(t0.EMP_ID = t1.EMP_ID) AND (t1.AREACODE = '613'))
noneOf is the universal counterpart to the existential anyOf. To have the condition evaluated for each instance it must be put inside of a subquery, which can be expressed as not exists (any of attributeName some condition). (All x such that !y = !Exist x such that y).
Likewise the syntax employee.noneOf("phoneNumbers").get("areaCode").equal("613")
is not supported for the equal must go inside a subQuery.
This method saves you from writing the sub query yourself. The above is equivalent to the following expression:
ExpressionBuilder employee = new ExpressionBuilder();
ExpressionBuilder phone = new ExpressionBuilder();
ReportQuery subQuery = new ReportQuery(Phone.class, phone);
subQuery.retreivePrimaryKeys();
subQuery.setSelectionCriteria(phone.equal(employee.anyOf("phoneNumbers").and(
phone.get("areaCode").equal("613")));
Expression exp = employee.notExists(subQuery);
criteria - must have its own builder, as it will become the
separate selection criteria of a subQuery.public Expression normalize(org.eclipse.persistence.internal.expressions.ExpressionNormalizer normalizer)
