The Availability interface defines methods to test availability of data.

Method Summary

All Methods Instance Methods Abstract Methods Default Methods
Modifier and Type	Method	Description
`int`	`available()`	Determines the number of available datagram from a `DatagramTransmitter`.
`default boolean`	`hasAvailable()`	Determines whether a datagram is available from a `DatagramTransmitter`.

- Method Detail
  - available
```
int available()
       throws IOException
```
    Determines the number of available datagram from a DatagramTransmitter. Use the DatagramDestination extenison's DatagramDestination.receive() method for retrieving available datagrams.
    
    Returns:
    
    The number of datagrams ready to be retrieved .
    
    Throws:
    
    IOException - Thrown in case opening or accessing an open line (connection, junction, link) caused problems.
  - hasAvailable
```
default boolean hasAvailable()
                      throws IOException
```
    Determines whether a datagram is available from a DatagramTransmitter. Use the DatagramDestination extenison's DatagramDestination.receive() method for retrieving the available datagram.
    
    Returns:
    
    True in case there is a datagram ready to be retrieved .
    
    Throws:
    
    IOException - Thrown in case opening or accessing an open line (connection, junction, link) caused problems.
