Package org.omg.CORBA

Class Any

java.lang.Object
org.omg.CORBA.Any
All Implemented Interfaces:
Serializable, IDLEntity
Direct Known Subclasses:
AnyImpl
public abstract class Any extends Object implements IDLEntity
Serves as a container for any data that can be described in IDL or for any IDL primitive type. An Any object is used as a component of a NamedValue object, which provides information about arguments or return values in requests, and which is used to define name/value pairs in Context objects.

An Any object consists of two parts:

  1. a data value
  2. a TypeCode object describing the type of the data value contained in the Any object. For example, a TypeCode object for an array contains a field for the length of the array and a field for the type of elements in the array. (Note that in this case, the second field of the TypeCode object is itself a TypeCode object.)

<a name="anyOps" A large part of the Any class consists of pairs of methods for inserting values into and extracting values from an Any object.

For a given primitive type X, these methods are:

void insert_X(X x)
This method allows the insertion of an instance x of primitive type X into the value field of the Any object. Note that the method insert_X also resets the Any object's type field if necessary.
X extract_X()
This method allows the extraction of an instance of type X from the Any object.

This method throws the exception BAD_OPERATION under two conditions:

  1. the type of the element contained in the Any object is not X
  2. the method extract_X is called before the value field of the Any object has been set

There are distinct method pairs for each primitive IDL data type (insert_long and extract_long, insert_string and extract_string, and so on).

The class Any also has methods for getting and setting the type code, for testing two Any objects for equality, and for reading an Any object from a stream or writing it to a stream.

    • equal

      public abstract boolean equal(Any a)
      Checks for equality between this Any object and the given Any object. Two Any objects are equal if both their values and type codes are equal.
      Parameters:
      a - the Any object to test for equality
      Returns:
      true if the Any objects are equal; false otherwise
      See Also:

    • type

      public abstract TypeCode type()
      Returns type information for the element contained in this Any object.
      Returns:
      the TypeCode object containing type information about the value contained in this Any object

    • type

      public abstract void type(TypeCode t)
      Sets this Any object's type field to the given TypeCode object and clears its value.

      Note that using this method to set the type code wipes out the value if there is one. The method is provided primarily so that the type may be set properly for IDL out parameters. Generally, setting the type is done by the insert_X methods, which will set the type to X if it is not already set to X.

      Parameters:
      t - the TypeCode object giving information for the value in this Any object

    • read_value

      public abstract void read_value(InputStream is, TypeCode t) throws MARSHAL

      Parameters:
      is - the org.omg.CORBA.portable.InputStream object from which to read the value contained in this Any object
      t - a TypeCode object containing type information about the value to be read
      Throws:
      MARSHAL - when the given TypeCode object is not consistent with the value that was contained in the input stream

    • write_value

      public abstract void write_value(OutputStream os)
      Writes out the value of this Any object to the given output stream. If both typecode and value need to be written, use create_output_stream() to create an OutputStream, then use write_any on the OutputStream.

      If this method is called on an Any object that has not had a value inserted into its value field, it will throw the exception java.lang.NullPointerException.

      Parameters:
      os - the org.omg.CORBA.portable.OutputStream object into which to marshal the value of this Any object

    • create_output_stream
