Method Detail

getRelativePath

public static String getRelativePath(String targetPath,
                                     String basePath)
                              throws org.zanata.util.PathUtil.PathResolutionException

Get the relative path from one file to another, specifying the directory separator. If one of the provided resources does not exist, it is assumed to be a file unless it ends with '/' or '\'.

Parameters:

target - targetPath is calculated to this file

base - basePath is calculated from this file

Returns:

Throws:

PathResolutionException - if no relative path exists

org.zanata.util.PathUtil.PathResolutionException

getRelativePath

public static String getRelativePath(String targetPath,
                                     String basePath,
                                     String pathSeparator)
                              throws org.zanata.util.PathUtil.PathResolutionException

Get the relative path from one file to another, specifying the directory separator. If one of the provided resources does not exist, it is assumed to be a file unless it ends with '/' or '\'.

Parameters:

target - targetPath is calculated to this file

base - basePath is calculated from this file

separator - directory separator. The platform default is not assumed so that we can test Unix behaviour when running on Windows (for example)

Returns:

Throws:

PathResolutionException - if no relative path exists

org.zanata.util.PathUtil.PathResolutionException

getSubPath

public static String getSubPath(File f,
                                File parentDir)
                         throws IOException,
                                org.zanata.util.PathUtil.PathResolutionException

Returns relative path from parentDir to f. NB: assumes that f is inside parentDir.

Parameters:

f - a file inside parentDir

parentDir -

Returns:

Throws:

IOException

                            File dir)
                     throws IOException

Creates dir and its parents

Parameters:

dir - directory to create, along with any required parent dirs

Throws:
