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.

read_fixed

public BigDecimal read_fixed()
Reads a BigDecimal number.

Returns:
a java.math.BigDecimal number

read_Context

public Context read_Context()
Reads a CORBA context from the stream.

Returns:
a CORBA context
See Also:
portable package comments for unimplemented features

read_Object

public Object read_Object(Class clz)
Unmarshals an object and returns a CORBA Object, which is an instance of the class passed as its argument. This class is the stub class of the expected type.

Parameters:
clz - The Class object for the stub class which corresponds to the type that is statistically expected, or the Class object for the RMI/IDL interface type that is statistically expected.
Returns:
an Object instance of clz read from this stream
