Method Detail

offer

public void offer(int credits)

Description copied from interface: Sender

indicates pending deliveries

Specified by:

offer in interface Sender

Parameters:

credits - the number of pending deliveries

send

public int send(byte[] bytes,
       int offset,
       int length)

Description copied from interface: Sender

Sends some data for the current delivery. The application may call this method multiple times for the same delivery.

Specified by:

send in interface Sender

Returns:

the number of bytes accepted TODO Proton-j current copies all the bytes it has been given so the return value will always be length. Should this be changed? How does Proton-c behave? What should the application do if the number of bytes accepted is smaller than length.

abort

public void abort()

Description copied from interface: Sender

Abort the current delivery. Note "pn_link_abort" is commented out in the .h

Specified by:

abort in interface Sender

advance

public boolean advance()

Description copied from interface: Link

Attempts to advance the current delivery. Advances it to the next delivery if one exists, else null. The behaviour of this method is different for senders and receivers.

Specified by:

advance in interface Link

Specified by:

advance in interface Sender

Overrides:

advance in class LinkImpl

Returns:

true if it can advance, false if it cannot TODO document the meaning of the return value more fully. Currently Senderimpl only returns false if there is no current delivery

See Also:

TODO fully state the rules regarding when you have to call this method, what happens if you don't call it before creating another delivery etc.

setCredit

public void setCredit(int credit)

Overrides:

setCredit in class LinkImpl
