JRE 8 rt.jar - javax.* Package Source Code

JRE 8 rt.jar is the JAR file for JRE 8 RT (Runtime) libraries. JRE (Java Runtime) 8 is the runtime environment included in JDK 8. JRE 8 rt.jar libraries are divided into 6 packages:

com.* - Internal Oracle and Sun Microsystems libraries
java.* - Standard Java API libraries.
javax.* - Extended Java API libraries.
jdk.* -  JDK supporting libraries.
org.* - Third party libraries.
sun.* - Old libraries developed by Sun Microsystems.

/*
  We considered generifying this interface as ValueExp<T>, where T is
  the Java type that this expression generates.  This allows some additional
  checking in the various methods of the Query class, but in practice
  not much.  Typically you have something like
  Query.lt(Query.attr("A"), Query.value(5)).  We can arrange for Query.value
  to have type ValueExp<Integer> (or maybe ValueExp<Long> or ValueExp<Number>)
  but for Query.attr we can't do better than ValueExp<?> or plain ValueExp.
  So even though we could define Query.lt as:
  QueryExp <T> lt(ValueExp<T> v1, ValueExp<T> v2)
  and thus prevent comparing a
  number against a string, in practice the first ValueExp will almost always
  be a Query.attr so this check serves no purpose.  You would have to
  write Query.<Number>attr("A"), for example, which would be awful.  And,
  if you wrote Query.<Integer>attr("A") you would then discover that you
  couldn't compare it against Query.value(5) if the latter is defined as
  ValueExp<Number>, or against Query.value(5L) if it is defined as
  ValueExp<Integer>.

  Worse, for Query.in we would like to define:
  QueryExp <T> in(ValueExp<T> val, ValueExp<T>[] valueList)
  but this is unusable because you cannot write
  "new ValueExp<Integer>[] {...}" (the compiler forbids it).

  The few mistakes you might catch with this generification certainly
  wouldn't justify the hassle of modifying user code to get the checks
  to be made and the "unchecked" warnings that would arise if it
  wasn't so modified.

  We could reconsider this if the Query methods were augmented, for example
  with:
  AttributeValueExp<Number> numberAttr(String name);
  AttributeValueExp<String> stringAttr(String name);
  AttributeValueExp<Boolean> booleanAttr(String name);
  QueryExp <T> in(ValueExp<T> val, Set<ValueExp<T>> valueSet).
  But it's not really clear what numberAttr should do if it finds that the
  attribute is not in fact a Number.
