                        int start,
                        int limit)

覆盖:

parseURL 在类中 URLStreamHandler

hashCode

protected int hashCode(URL u)

覆盖:

hashCode 在类中 URLStreamHandler

sameFile

protected boolean sameFile(URL u1,
                           URL u2)

覆盖:

                              throws IOException

抛出:

IOException

setUseFastConnectionExceptions

public static void setUseFastConnectionExceptions(boolean useFastConnectionExceptions)

Set if a generic static exception can be thrown when a URL cannot be connected. This optimization is used during class loading to save creating lots of exceptions which are then swallowed.

参数:

useFastConnectionExceptions - if fast connection exceptions can be used.
