Method Detail

getRemainingPath

protected static java.lang.String getRemainingPath(java.util.List<java.lang.String> tokens,
                                                   int i,
                                                   int end)

Get the remaining path from some tokens

Parameters:

tokens - the tokens

i - the current location

end - the end index

Returns:

the remaining path

Throws:

java.lang.IllegalArgumentException - for null tokens or i is out of range

getTokens

public static java.util.List<java.lang.String> getTokens(java.lang.String path)

Get the tokens that comprise this path.

Parameters:

path - the path

Returns:

the tokens or null if the path is empty

Throws:

java.lang.IllegalArgumentException - if the path is null

getTokens

public static void getTokens(java.util.List<java.lang.String> list,
                             java.lang.String path)

Get the tokens that comprise this path and append them to the list.

Parameters:

path - the path

Throws:

java.lang.IllegalArgumentException - if the path is null

getRemainingPath

public static java.lang.String getRemainingPath(java.util.List<java.lang.String> tokens,
                                                int i)

Get the remaining path from some tokens

Parameters:

tokens - the tokens

i - the current location

Returns:

the remaining path

Throws:

java.lang.IllegalArgumentException - for null tokens or i is out of range

applySpecialPaths

public static java.lang.String applySpecialPaths(java.lang.String path)
                                          throws java.lang.IllegalArgumentException
