■Merge - Creates a combined signature file from several signature files representing different Java APIs in one Java runtime environment according to the JSR 68 rules.

The SigTest tool distribution includes a Java™ Archive (JAR) file used for developing a signature test and one for distribution within a finished test suite to run its signature test. The description of each follows:

■sigtestdev.jar - Contains classes for running the commands used during signature test development.

■sigtest.jar - Contains only the classes for running the SignatureTest command. This file is distributed in a finished test suite.

Test suite developers perform these operations while using sigtestdev.jar to develop a signature test.

1.Run the Setup command to create a signature file from either an API defined by a specification or a reference API implementation.

2.Include the files required to run the signature test in the finished test suite distribution.

Testers perform these operations using sigtest.jar while testing the implementation, as described in “Running a Signature Test With the JavaTest Harness” on page 23.

1.Run the SignatureTest command to compare the reference representation of the API in the signature file to the API under test and produce a report. This step is usually performed under the control of the JavaTest harness as described in “Running a Signature Test With the JavaTest Harness” on page 23.

2.Interpret the report.

Reflection and Static Run Modes

Two run modes are available during command execution. These modes determine how the class descriptions are examined and retrieved, as follows:

■Reflection Mode - Uses reflection to examine API classes and retrieve information about them. The reflection mode is of greatest advantage when the API to be analyzed has no external class files.

■Static Mode - Specified with the -staticflag, the tool parses only the class files listed in the -classpathcommand-line argument.

Sun Microsystems, founded in 1982, was a significant player in the computing industry, best known for its innovative technology solutions and workstations, particularly the Sun-4, which represented a key milestone in the company's history. The Sun-4 architecture, launched in 1987, utilized the SPARC (Scalable Processor Architecture) RISC processor, notable for its high performance and scalability.

One of the primary features of Sun Microsystems' platforms was their ability to efficiently handle multitasking and resource management, making them ideal for enterprise-level applications and development environments. Sun-4 workstations boasted impressive graphics capabilities with the addition of advanced graphical user interfaces, support for color displays, and the SUNVIEW windowing system, which enhanced user experience and productivity.

The Sun-4 systems also supported the SunOS operating system, which was based on UNIX. This operating system was engineered for stability and robustness, offering features like multiuser support, networked environments, and advanced security options. Moreover, SunOS provided seamless integration with various programming languages, including C and C++, facilitating software development that aligned with industry standards.

Another standout characteristic of Sun Microsystems was its commitment to open systems and standards. By providing developers with comprehensive tools and environments, such as the Standardized Application Programming Interface (API) and support for networking protocols, Sun facilitated interoperability among different computing platforms. The emphasis on open architecture also meant that customers could easily upgrade their systems without being locked into proprietary solutions.

Sun Microsystems was also ahead of its time with innovations in network computing. Their workstations were among the first to support network file systems and distributed computing concepts, enabling seamless data sharing across multiple systems. With the introduction of the Network File System (NFS), Sun revolutionized how data was accessed and managed across networks, which played a significant role in the evolving landscape of client-server computing.

In summary, the Sun Microsystems 2 and its successive innovations in workstation technology highlighted the company's forward-thinking approach. By integrating powerful performance with open systems, robust operating systems, and advanced networking capabilities, Sun laid the groundwork for modern computing, influencing various sectors from academia to enterprise solutions. Even after its acquisition by Oracle in 2010, the legacy of Sun Microsystems continues to be felt across the computing industry.
