EZSequence -- Protocol for an EZSequence
A sequence generated using an EZGraph instance returns an object of this type
Returns the current value of the sequence.
After a sequence has been created and a selector is set, this method allows the user to specify a single unsigned integer argument that is required by the message that the selector implies.
For example, suppose you have created an EZGraph called "heightGraph"
If one has an object "dog" in which there is a method
- getFriendHeight: (unsigned)h;
And one wants to create a line to plot the 5th dog,
then the EZsequence can be created with a command like:
id sequence = [heightGraph createSequence: "aName"
[sequence setUnsignedArg: 4];
