950:(RTSJ) is a set of interfaces and behavioral refinements that enable real-time computer programming in the Java programming language. RTSJ 1.0 was developed as JSR 1 under the Java Community Process, which approved the new standard in November, 2001. RTSJ 2.0 is being developed under JSR 282. A draft version is available at JSR 282 JCP Page. More information can be found at RTSJ 2.0

1001:). This use is required because Java operators are not based on code generation. As a result, windows are automatically managed by the runtime to guarantee SPL window semantics. Developers can check for valid window configurations during runtime by checking the window policy associated to a given input port.
985:
With the windowing library, developers can specify different eviction and trigger policies but can implement the event handling actions independently of the window policy details. There are a few differences when implementing primitive operators in C++ and Java that take advantage of the SPL window
937:
The RTSJ addressed the critical issues by mandating a minimum (only two) specification for the threading model (and allowing other models to be plugged into the VM) and by providing for areas of memory that are not subject to garbage collection, along with threads that are not preempt able by the
965:
The windowing library is a set of classes available in the
Streams Processing Language (SPL) Runtime C++ API and the SPL Java™ Operator API. The library is used to implement primitive operators that need windows following the SPL window semantics. Using the windowing library provides a consistent
989:
In the C++ implementation, developers have no obligation to use the window library (the preferred practice is to use library). They are free to use the SPL Operator Code
Generation API just to get the specified window policy for a given operator instance. Then, they can generate code using other
969:
SPL offers both tumbling and sliding windows. Both types of windows keep all the incoming data in memory until its tuple eviction policy triggers. Use the SPL support for windows when the functionality required by the primitive operator can be built using the semantics provided by SPL window
918:
Java's sophisticated memory management, native support for threading and concurrency, type safety, and relative simplicity have created a demand for its use in many domains. Its capabilities have been enhanced to support real time computational needs:

operator. This action occurs because this operator has different eviction and trigger semantics than the ones provided by SPL. This operator needs to maintain only unique tuples and discards all repeated tuples that are received within a time window.

Because Java threads support priorities, Java locking mechanisms support priority inversion avoidance techniques, such as priority inheritance or the priority ceiling protocol.
