Constructor Detail

TestAbstractReceiver

public TestAbstractReceiver(IOPort container)
                     throws IllegalActionException

Construct an empty receiver with the specified container.

Parameters:

container - The container of the receiver.

Throws:

IllegalActionException - If the container does not accept this receiver.

Method Detail

get

public Token get()
          throws NoTokenException

Get a token from this receiver.

Specified by:

get in interface Receiver

Specified by:

get in class AbstractReceiver

Returns:

A token read from the receiver.

Throws:

NoTokenException - If there is no token.

hasRoom

public boolean hasRoom()

Return true if the receiver has room to put a token into it (via the put() method). Returning true in this method guarantees that the next call to put() will not result in an exception.

Specified by:

hasRoom in interface Receiver

Specified by:

hasRoom in class AbstractReceiver

Returns:

True

hasRoom

public boolean hasRoom(int numberOfTokens)

Return true if the receiver has room to put the specified number of tokens into it (via the put() method). Returning true in this method guarantees that the next numberOfTokens calls to put() or a corresponding call to putArray() will not result in an exception.

Specified by:

hasRoom in interface Receiver

Specified by:

hasRoom in class AbstractReceiver

Parameters:

numberOfTokens - The number of tokens to put into this receiver.

Returns:

True

hasToken

public boolean hasToken()

Return true if the receiver contains a token that can be obtained by calling the get() method. In an implementation, returning true in this method guarantees that the next call to get() will not result in an exception.

Specified by:

hasToken in interface Receiver

Specified by:

hasToken in class AbstractReceiver

Returns:

True

hasToken

public boolean hasToken(int numberOfTokens)

Return true if the receiver contains the specified number of tokens. In an implementation, returning true in this method guarantees that the next numberOfTokens calls to get(), or a corresponding call to getArray(), will not result in an exception.

Specified by:

hasToken in interface Receiver

Specified by:

hasToken in class AbstractReceiver

Parameters:

numberOfTokens - The number of tokens desired.

Returns:

True

isKnown

public boolean isKnown()

Return true. Most domains have no notion of the state of the receiver being unknown. It is always known whether there is a token available. Certain domains with fixed point semantics, however, such as SR, will need to override this method.

Specified by:

isKnown in interface Receiver

Overrides:

isKnown in class AbstractReceiver

Returns:

True.

put

public void put(Token token)
         throws NoRoomException,
                IllegalActionException

Put the specified token into this receiver.

Specified by:

put in interface Receiver

Specified by:

put in class AbstractReceiver

Parameters:

token - The token to put into the receiver.

Throws:

NoRoomException - If there is no room in the receiver.

IllegalActionException - If the put fails (e.g. because of incompatible types).
