| 27 | * Shared source for 'java' command line tool. |
| 28 | * |
| 29 | * If JAVA_ARGS is defined, then acts as a launcher for applications. For |
| 30 | * instance, the JDK command line tools such as javac and javadoc (see |
| 31 | * makefiles for more details) are built with this program. Any arguments |
| 32 | * prefixed with '-J' will be passed directly to the 'java' command. |
| 33 | */ |
| 34 | |
| 35 | /* |
| 36 | * One job of the launcher is to remove command line options which the |
| 37 | * vm does not understand and will not process. These options include |
| 38 | * options which select which style of vm is run (e.g. -client and |
| 39 | * -server) as well as options which select the data model to use. |
| 40 | * Additionally, for tools which invoke an underlying vm "-J-foo" |
| 41 | * options are turned into "-foo" options to the vm. This option |
| 42 | * filtering is handled in a number of places in the launcher, some of |
| 43 | * it in machine-dependent code. In this file, the function |
| 44 | * CheckJvmType removes vm style options and TranslateApplicationArgs |
| 45 | * removes "-J" prefixes. The CreateExecutionEnvironment function processes |
| 46 | * and removes -d<n> options. On unix, there is a possibility that the running |
| 47 | * data model may not match to the desired data model, in this case an exec is |
| 48 | * required to start the desired model. If the data models match, then |
| 49 | * ParseArguments will remove the -d<n> flags. If the data models do not match |
| 50 | * the CreateExecutionEnviroment will remove the -d<n> flags. |

| 1947 | * |
| 1948 | * The functionality of the jvm.cfg file is subject to change without |
| 1949 | * notice and the mechanism will be removed in the future. |
| 1950 | * |
| 1951 | * The lexical structure of the jvm.cfg file is as follows: |
| 1952 | * |
| 1953 | * jvmcfg := { vmLine } |
| 1954 | * vmLine := knownLine |
| 1955 | * | aliasLine |
| 1956 | * | warnLine |
| 1957 | * | ignoreLine |
| 1958 | * | errorLine |
| 1959 | * | predicateLine |
| 1960 | * | commentLine |
| 1961 | * knownLine := flag "KNOWN" EOL |
| 1962 | * warnLine := flag "WARN" EOL |
| 1963 | * ignoreLine := flag "IGNORE" EOL |
| 1964 | * errorLine := flag "ERROR" EOL |
| 1965 | * aliasLine := flag "ALIASED_TO" flag EOL |
| 1966 | * predicateLine := flag "IF_SERVER_CLASS" flag EOL |
| 1967 | * commentLine := "#" text EOL |
| 1968 | * flag := "-" identifier |
| 1969 | * |
| 1970 | * The semantics are that when someone specifies a flag on the command line: |
| 1971 | * - if the flag appears on a knownLine, then the identifier is used as |
| 1972 | * the name of the directory holding the JVM library (the name of the JVM). |
| 1973 | * - if the flag appears as the first flag on an aliasLine, the identifier |
| 1974 | * of the second flag is used as the name of the JVM. |
| 1975 | * - if the flag appears on a warnLine, the identifier is used as the |
| 1976 | * name of the JVM, but a warning is generated. |
| 1977 | * - if the flag appears on an ignoreLine, the identifier is recognized as the |
| 1978 | * name of a JVM, but the identifier is ignored and the default vm used |
| 1979 | * - if the flag appears on an errorLine, an error is generated. |
| 1980 | * - if the flag appears as the first flag on a predicateLine, and |
| 1981 | * the machine on which you are running passes the predicate indicated, |
| 1982 | * then the identifier of the second flag is used as the name of the JVM, |
| 1983 | * otherwise the identifier of the first flag is used as the name of the JVM. |
| 1984 | * If no flag is given on the command line, the first vmLine of the jvm.cfg |
| 1985 | * file determines the name of the JVM. |
| 1986 | * PredicateLines are only interpreted on first vmLine of a jvm.cfg file, |
| 1987 | * since they only make sense if someone hasn't specified the name of the |
| 1988 | * JVM on the command line. |
| 1989 | * |
| 1990 | * The intent of the jvm.cfg file is to allow several JVM libraries to |
| 1991 | * be installed in different subdirectories of a single JRE installation, |
| 1992 | * for space-savings and convenience in testing. |
| 1993 | * The intent is explicitly not to provide a full aliasing or predicate |
| 1994 | * mechanism. |
