方法详细资料

abortIfNeeded

protected final void abortIfNeeded()

Aborts with subclass specific abortion logic executed if needed. Note the interrupted status of the thread is cleared by this method.

抛出:

AbortedException - if found necessary.

abort

public void abort()

Can be used to provide abortion logic prior to throwing the AbortedException. If the wrapped InputStream is also an instance of this class, then it will also be aborted, otherwise this is a no-op.

isAborted

protected boolean isAborted()

read

public int read()
         throws IOException

覆盖:

read 在类中 FilterInputStream

抛出:

IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

覆盖:

read 在类中 FilterInputStream

抛出:

IOException

skip

public long skip(long n)
          throws IOException

覆盖:

skip 在类中 FilterInputStream

抛出:

IOException

available

              throws IOException

覆盖:

available 在类中 FilterInputStream

抛出:

IOException

close

public void close()
           throws IOException

指定者:

close 在接口中 Closeable

指定者:

close 在接口中 AutoCloseable

覆盖:

mark

public void mark(int readlimit)

覆盖:

mark 在类中 FilterInputStream

reset

public void reset()
           throws IOException

覆盖:

reset 在类中 FilterInputStream

抛出:

IOException

markSupported

public boolean markSupported()

覆盖:

markSupported 在类中 FilterInputStream

release

public void release()

从接口复制的说明: Releasable

Releases the allocated resource. This method should not be called except by the caller who allocated the resource at the very top of the call stack. This allows, typically, a Closeable resource to be not unintentionally released owing to the calling of the Closeable.close() methods by implementation deep down in the call stack.

For example, the creation of a ResettableInputStream would entail physically opening a file. If the opened file is meant to be closed only (in a finally block) by the very same code block that created it, then it is necessary that the release method must not be called while the execution is made in other stack frames. In such case, as other stack frames may inadvertently or indirectly call the close method of the stream, the creator of the stream would need to explicitly disable the accidental closing via ResettableInputStream#disableClose(), so that the release method becomes the only way to truly close the opened file.
