Class InputStream

  • All Implemented Interfaces:
    Closeable, AutoCloseable
    Direct Known Subclasses:
    InputStream

    public abstract class InputStream
extends InputStream
    InputStream is the Java API for reading IDL types from CDR marshal streams. These methods are used by the ORB to unmarshal IDL types as well as to extract IDL types out of Anys. The _array versions of the methods can be directly used to read sequences and arrays of IDL types.
    Since:
    JDK1.2

      • read

        public int read​()
         throws IOException
        Description copied from class: InputStream
        Reads the next byte of data from the input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown.

        A subclass must provide an implementation of this method.

        Specified by:
        read in class InputStream
        Returns:
        the next byte of data, or -1 if the end of the stream is reached.
        Throws:
        IOException - if an I/O error occurs.
