BufferedLineReaderInputStream

public BufferedLineReaderInputStream(java.io.InputStream instream,
                                     int buffersize,
                                     int maxLineLen)

BufferedLineReaderInputStream

public BufferedLineReaderInputStream(java.io.InputStream instream,
                                     int buffersize)

方法详细资料

ensureCapacity

public void ensureCapacity(int len)

fillBuffer

public int fillBuffer()
               throws java.io.IOException

抛出:

java.io.IOException

hasBufferedData

public boolean hasBufferedData()

truncate

public void truncate()

read

public int read()
         throws java.io.IOException

覆盖:

read 在类中 java.io.FilterInputStream

抛出:

java.io.IOException

read

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

覆盖:

read 在类中 java.io.FilterInputStream

抛出:

java.io.IOException

read

public int read(byte[] b)
         throws java.io.IOException

覆盖:

read 在类中 java.io.FilterInputStream

抛出:

java.io.IOException

markSupported

public boolean markSupported()

覆盖:

markSupported 在类中 java.io.FilterInputStream

readLine

public int readLine(ByteArrayBuffer dst)
             throws MaxLineLimitException,
                    java.io.IOException

从类复制的说明: LineReaderInputStream

Reads one line of text into the given ByteArrayBuffer.

指定者:

readLine 在类中 LineReaderInputStream

参数:

dst - Destination

返回:

number of bytes copied or -1 if the end of the stream has been reached.

抛出:

MaxLineLimitException - if the line exceeds a limit on the line length imposed by a subclass.

java.io.IOException - in case of an I/O error.

indexOf

public int indexOf(byte[] pattern,
                   int off,
                   int len)

indexOf

public int indexOf(byte[] pattern)

Implements quick search algorithm as published by

SUNDAY D.M., 1990, A very fast substring search algorithm, Communications of the ACM . 33(8):132-142.

参数:

pattern - byte[]

返回:

int

indexOf

public int indexOf(byte b,
                   int off,
                   int len)

indexOf

public int indexOf(byte b)

byteAt

public int byteAt(int pos)

capacity

public int capacity()

toString

public java.lang.String toString()

覆盖:

toString 在类中 java.lang.Object

unread

public boolean unread(ByteArrayBuffer buf)

从类复制的说明: LineReaderInputStream

Tries to unread the last read line. Implementation may refuse to unread a new buffer until the previous unread one has been competely consumed. Implementations will directly use the byte array backed by buf, so make sure to not alter it anymore once this method has been called.

指定者:

unread 在类中 LineReaderInputStream

参数:

buf - ByteArrayBuffer

返回:

true if the unread has been succesfull.
