Method Detail

getOptionalProperty

protected static String getOptionalProperty(String name)

getRequiredProperty

protected static String getRequiredProperty(String name)

convertHostName

public static String convertHostName(String host)

asPath

protected static String asPath(Vector<String> paths,
                               HostDescription hd)

Converts the given vector of path elements to a path using an O/S-specific path separator based on the host description.

getPathSep

protected static char getPathSep(HostHelper.OSType os)

getFileSep

protected static char getFileSep(HostHelper.OSType os)

expandEnvVars

public static String expandEnvVars(String str)

This method is for use with post-mortem tools and requires all "environment variables" used in parsed input files to be passed in as system properties on the tool's command line. EXTRA_JTESTS is for use by Gemfire addons like the tools projects.

For $JAVA_HOME use JAVA_HOME. For $JTESTS use JTESTS. For $EXTRA_JTESTS use EXTRA_JTESTS. For $GEMFIRE use gemfire.home. $PWD automatically uses user.dir.

expandEnvVars

protected static Vector expandEnvVars(Vector<String> paths,
                                      HostDescription hd)

Expands the environment variables in the path vector using the host description.

expandPath

public static String expandPath(String path)

Expands $JTESTS in the given path using the host description and version for this hydra client JVM. If the path does not exist in the versioned test tree (e.g., $JTESTS/../tests651 for version 651), it uses the current test tree regardless of whether the path is valid. Also expands $PWD using user.dir.

expandEnvVars

public static String expandEnvVars(String path,
                                   HostDescription hd)

Expands the environment variables in the path using the host description. If the host description is null, the path is expanded using system properties.
