Class SharedByteArrayInputStream

  • All Implemented Interfaces:
    java.io.Closeable, java.lang.AutoCloseable, SharedInputStream
    public class SharedByteArrayInputStream
extends java.io.ByteArrayInputStream
implements SharedInputStream
    A ByteArrayInputStream that implements the SharedInputStream interface, allowing the underlying byte array to be shared between multiple readers.
    Since:
    JavaMail 1.4

      • SharedByteArrayInputStream

        public SharedByteArrayInputStream​(byte[] buf)
        Create a SharedByteArrayInputStream representing the entire byte array.
        Parameters:
        buf - the byte array

      • SharedByteArrayInputStream

        public SharedByteArrayInputStream​(byte[] buf,
                                  int offset,
                                  int length)
        Create a SharedByteArrayInputStream representing the part of the byte array from offset for length bytes.
        Parameters:
        buf - the byte array
        offset - offset in byte array to first byte to include
        length - number of bytes to include

    • Method Detail

      • getPosition

        public long getPosition()
        Return the current position in the InputStream, as an offset from the beginning of the InputStream.
        Specified by:
        getPosition in interface SharedInputStream
        Returns:
        the current position

      • newStream

        public java.io.InputStream newStream​(long start,
                                     long end)
        Return a new InputStream representing a subset of the data from this InputStream, starting at start (inclusive) up to end (exclusive). start must be non-negative. If end is -1, the new stream ends at the same place as this stream. The returned InputStream will also implement the SharedInputStream interface.
        Specified by:
        newStream in interface SharedInputStream
        Parameters:
        start - the starting position
        end - the ending position + 1
        Returns:
        the new stream
