直接已知子类:

ResettableInputStream

public class ReleasableInputStream
extends SdkFilterInputStream
implements Releasable

An input stream that can have the close operation disabled (to avoid accidentally being closed). This is necessary, for example, when an input stream needs to be marked-and-reset multiple times but only as long as the input stream has not been closed. To survive not being accidentally closed, the close method can be disabled via disableClose().

The creator of this input stream should therefore always call release() in a finally block to truly release the underlying resources.

ReleasableInputStream

protected ReleasableInputStream(java.io.InputStream is)

This constructor is not meant to be used directly. Use wrap(InputStream) instead.

方法详细资料

close

public final void close()

If closeDisabled is false, closes this input stream and releases any system resources associated with the stream. Otherwise, this method does nothing.

指定者:

close 在接口中 java.lang.AutoCloseable

指定者:

close 在接口中 java.io.Closeable

覆盖:

close 在类中 SdkFilterInputStream

release

public final void release()

Closes the underlying stream file and releases any system resources associated.

指定者:

release 在接口中 Releasable

覆盖:

release 在类中 SdkFilterInputStream

isCloseDisabled

public final boolean isCloseDisabled()

Returns true if the close method has been disabled; false otherwise. Once the close method is disabled, caller would be responsible to release resources via release().

disableClose

public final <T extends ReleasableInputStream> T disableClose()

Used to disable the close method. Once the close method is disabled, caller would be responsible to release resources via release().

wrap

public static ReleasableInputStream wrap(java.io.InputStream is)

Wraps the given input stream into a ReleasableInputStream if necessary. Note if the given input stream is a FileInputStream, a ResettableInputStream which is a specific subclass of ReleasableInputStream will be returned.
