Method Detail

getSystemEnvVars

public static java.util.Properties getSystemEnvVars()
                                             throws java.io.IOException

Throws:

java.io.IOException

getSystemEnvVars

public static java.util.Properties getSystemEnvVars(boolean caseSensitive)
                                             throws java.io.IOException

Return the shell environment variables. If caseSensitive == true, then envar keys will all be upper-case.

Parameters:

caseSensitive - Whether environment variable keys should be treated case-sensitively.

Returns:

Properties object of (possibly modified) envar keys mapped to their values.

Throws:

java.io.IOException - in case of an error.

setEnvVarSource

public static void setEnvVarSource(OperatingSystemUtils.EnvVarSource source)

Set the source object to load the environment variables from. Default implementation should suffice. This is mostly for testing.

Parameters:

source - the EnvVarSource instance that loads the environment variables.
