path - path for which the free space should be detected the free space for the given path |
| getPrimaryGroup | | public static String getPrimaryGroup()(Code) | | Returns the primary group of the current user. This feature will be supported only on Unix.
On other systems null returns.
the primary group of the current user |
| getenv | | public static String getenv(String key)(Code) | | Returns the value of the environment variable given by key. This method is a work around for
VM versions which do not support getenv in an other way. At the first call all environment
variables will be loaded via an exec. On Windows keys are not case sensitive.

key - variable name for which the value should be resolved the value of the environment variable given by key |
| replaceString | | public static String replaceString(String destination, String what, String with)(Code) | | Returns a string resulting from replacing all occurrences of what in this string with with.
In opposite to the String.replaceAll method this method do not use regular expression or
other methods which are only available in JRE 1.4 and later. This method was special made to
mask masked slashes to avert a conversion during path translation.
Parameters:
destination - string for which the replacing should be performed
Parameters:
what - what string should be replaced
Parameters:
with - with what string what should be replaced a new String object if what was found in the given string, else the given string self |
| supported | | public static boolean supported(String method)(Code) | | Returns whether the given method will be supported with the given environment. Some methods
of this class are not supported on all operation systems.
Parameters:
method - name of the method true if the method will be supported with the current enivronment else false
throws:
RuntimeException - if the given method name does not exist |
| translatePath | | public static String translatePath(String destination, VariableSubstitutor vs)(Code) | | Translates a relative path to a local system path.
