Method Detail

getPathSegments

public static java.lang.String[] getPathSegments(java.lang.String path)

Split a path into segments, handles null as empty string.

Results: Path [] splits into 1 segments: [] Path [a] splits into 1 segments: [a] Path [a/] splits into 1 segments: [a] Path [a/b] splits into 2 segments: [a][b] Path [a/b/c] splits into 3 segments: [a][b][c] Path [/] splits into 0 segments: Path [/a] splits into 2 segments: [][a] Path [/a/b] splits into 3 segments: [][a][b] Path [/a/b/c] splits into 4 segments: [][a][b][c]

So, absolute paths are valid if length is >1 and first segment is "". Relative paths are valid if length is >0 and first segment is not "".

Parameters:

path - the path to split.

Returns:

String[] containing path segments, as per String.split("/").

getPath

public static java.lang.String getPath(java.lang.String[] pathSegments)

isValidAbsolutePath

public static boolean isValidAbsolutePath(java.lang.String[] pathSegments)

isValidRelativePath

public static boolean isValidRelativePath(java.lang.String[] pathSegments)

stepDownRelativePath

public static java.lang.String stepDownRelativePath(java.lang.String[] pathSegments)

Given a relative path as an array of path segments (see getPathSegments(String), return the path relative to the first path segment. I.e., drop the first segmentRejoin the given path segments after dropping the first path segment.

Parameters:

pathSegments - a string array of a relative path as returned by getPathSegments()

Returns:

the path relative to the first path segment.

toStringForPathSegments

public static java.lang.String toStringForPathSegments(java.lang.String[] pathSegments)

toStringForPathSegments

public static java.lang.String toStringForPathSegments(java.lang.String path)
