javax.mail.internet Interface SharedInputStream
- 所有已知实现子孙类:
- SharedByteArrayInputStream, SharedFileInputStream
public interface SharedInputStream
An InputStream that is backed by data that can be shared by multiple readers may implement this interface. This allows users of such an InputStream to determine the current position in the InputStream, and to create new InputStreams representing a subset of the data in the original InputStream. The new InputStream will access the same underlying data as the original, without copying the data.
Note that implementations of this interface must ensure that the
close
method does not close any underlying stream
that might be shared by multiple instances of SharedInputStream
until all shared instances have been closed.

getPosition
long getPosition()
- Return the current position in the InputStream, as an
offset from the beginning of the InputStream.
- 返回:
- the current position
newStream
InputStream newStream(long start, long end)
- Return a new InputStream representing a subset of the data
from this InputStream, starting at
start
(inclusive) up toend
(exclusive).start
must be non-negative. Ifend
is -1, the new stream ends at the same place as this stream. The returned InputStream will also implement the SharedInputStream interface. - 参数:
start
- the starting positionend
- the ending position + 1- 返回:
- the new stream
