Method Summary public  boolean canRead()      Returns true if there's an associated file. public  void close()      Closes the underlying stream. public  int getAvailable()      Returns the number of bytes available for reading. public  boolean hasSkip()      Returns true if there's an associated file. public  void init(FileInputStream is)      Initializes a VfsStream with an input/output stream pair. public  boolean lock(boolean shared, boolean block)      public  int read(byte[] buf, int offset, int length)      Reads bytes from the file. Parameters:   buf - a byte array receiving the data. Parameters:   offset - starting index to receive data. Parameters:   length - number of bytes to read. public  void seekStart(long offset)      Seeks based on the start. public  long skip(long n)      Skips bytes in the file. public  boolean unlock()      Constructor Detail FileReadStream public FileReadStream()(Code) Create a new FileReadStream. FileReadStream public FileReadStream(FileInputStream is)(Code) Create a new FileReadStream based on the java.io.* stream. Parameters:   is - the underlying input stream. FileReadStream public FileReadStream(FileInputStream is, Path path)(Code) Create a new FileReadStream based on the java.io.* stream. Parameters:   is - the underlying input stream. Parameters:   path - the associated Path. Method Detail canRead public boolean canRead()(Code) Returns true if there's an associated file. close public void close() throws IOException(Code) Closes the underlying stream. getAvailable public int getAvailable() throws IOException(Code) Returns the number of bytes available for reading. hasSkip public boolean hasSkip()(Code) Returns true if there's an associated file. init public void init(FileInputStream is)(Code) Initializes a VfsStream with an input/output stream pair. Before a read, the output will be flushed to avoid deadlocks. Parameters:   is - the underlying InputStream. Parameters:   os - the underlying OutputStream. lock public boolean lock(boolean shared, boolean block)(Code) read public int read(byte[] buf, int offset, int length) throws IOException(Code) Reads bytes from the file. Parameters:   buf - a byte array receiving the data. Parameters:   offset - starting index to receive data. Parameters:   length - number of bytes to read. the number of bytes read or -1 on end of file. seekStart public void seekStart(long offset) throws IOException(Code) Seeks based on the start. skip public long skip(long n) throws IOException(Code) Skips bytes in the file. Parameters:   n - the number of bytes to skip the actual bytes skipped. unlock public boolean unlock()(Code) Fields inherited from com.caucho.vfs.StreamImpl protected static NullPath _nullPath(Code)(Java Doc) protected Path _path(Code)(Java Doc) Methods inherited from com.caucho.vfs.StreamImpl public boolean canRead()(Code)(Java Doc) public boolean canWrite()(Code)(Java Doc) public void clearWrite()(Code)(Java Doc) public void close() throws IOException(Code)(Java Doc) public void closeWrite() throws IOException(Code)(Java Doc) public void flush() throws IOException(Code)(Java Doc) public void flushBuffer() throws IOException(Code)(Java Doc) public void flushToDisk() throws IOException(Code)(Java Doc) public Object getAttribute(String name) throws IOException(Code)(Java Doc) public Iterator getAttributeNames() throws IOException(Code)(Java Doc) public int getAvailable() throws IOException(Code)(Java Doc) public boolean getFlushOnNewline()(Code)(Java Doc) public byte[] getNewline()(Code)(Java Doc) public Path getPath()(Code)(Java Doc) public byte[] getReadBuffer()(Code)(Java Doc) public long getReadPosition()(Code)(Java Doc) public boolean hasSkip()(Code)(Java Doc) public int read(byte[] buffer, int offset, int length) throws IOException(Code)(Java Doc) public int readNonBlock(byte[] buffer, int offset, int length) throws IOException(Code)(Java Doc) public int readTimeout(byte[] buffer, int offset, int length, long timeout) throws IOException(Code)(Java Doc) public void removeAttribute(String name) throws IOException(Code)(Java Doc) public void seekEnd(long offset) throws IOException(Code)(Java Doc) public void seekStart(long offset) throws IOException(Code)(Java Doc) public void setAttribute(String name, Object value) throws IOException(Code)(Java Doc) public void setPath(Path path)(Code)(Java Doc) public void setWriteEncoding(String encoding)(Code)(Java Doc) public long skip(long n) throws IOException(Code)(Java Doc) public void write(byte[] buffer, int offset, int length, boolean isEnd) throws IOException(Code)(Java Doc) public boolean write(byte[] buf1, int off1, int len1, byte[] buf2, int off2, int len2, boolean isEnd) throws IOException(Code)(Java Doc) Methods inherited from java.lang.Object native protected Object clone() throws CloneNotSupportedException(Code)(Java Doc) public boolean equals(Object obj)(Code)(Java Doc) protected void finalize() throws Throwable(Code)(Java Doc) final native public Class getClass()(Code)(Java Doc) native public int hashCode()(Code)(Java Doc) final native public void notify()(Code)(Java Doc) final native public void notifyAll()(Code)(Java Doc) public String toString()(Code)(Java Doc) final native public void wait(long timeout) throws InterruptedException(Code)(Java Doc) final public void wait(long timeout, int nanos) throws InterruptedException(Code)(Java Doc) final public void wait() throws InterruptedException(Code)(Java Doc)
