Closeable, Readable, Flushable, Appendable

大道之行，天下为公。这篇文章主要讲述Closeable, Readable, Flushable, Appendable相关的知识，希望能为你提供帮助。
Closeable:

package java.io; import java.io.IOException; public interface Closeable { /** * Closes this stream and releases any system resources associated * with it. If the stream is already closed then invoking this * method has no effect. */ public void close() throws IOException; }

Readable:

package java.lang; import java.io.IOException; public interface Readable {/** * Attempts to read characters into the specified character buffer. * The buffer is used as a repository of characters as-is: the only * changes made are the results of a put operation. No flipping or * rewinding of the buffer is performed. */ public int read(java.nio.CharBuffer cb) throws IOException; }

Flushable:

package java.io; import java.io.IOException; public interface Flushable {/** * Flushes this stream by writing any buffered output to the underlying stream. */ void flush() throws IOException; }

Appendable:

package java.lang; import java.io.IOException; public interface Appendable {/** * Appends the specified character sequence to this Appendable. * @returnA reference to this Appendable */ Appendable append(CharSequence csq) throws IOException; /** * Appends a subsequence of the specified character sequence to this Appendable. * @returnA reference to this Appendable */ Appendable append(CharSequence csq, int start, int end) throws IOException; /** * Appends the specified character to this Appendable. * @returnA reference to this Appendable */ Appendable append(char c) throws IOException; }
