构造器详细资料

IMAPInputStream

public IMAPInputStream(IMAPMessage msg,
                       String section,
                       int max,
                       boolean peek)

Create an IMAPInputStream.

参数:

msg - the IMAPMessage the data will come from

section - the IMAP section/part identifier for the data

max - the number of bytes in this section

peek - peek instead of fetch?

方法详细资料

read

public int read()
         throws IOException

Reads the next byte of data from this buffered input stream. If no byte is available, the value -1 is returned.

指定者:

read 在类中 InputStream

抛出:

IOException

read

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

Reads up to len bytes of data from this input stream into the given buffer.

Returns the total number of bytes read into the buffer, or -1 if there is no more data.

Note that this method mimics the "weird !" semantics of BufferedInputStream in that the number of bytes actually returned may be less that the requested value. So callers of this routine should be aware of this and must check the return value to insure that they have obtained the requisite number of bytes.

Reads up to b.length bytes of data from this input stream into an array of bytes.
