Class Inni

java.lang.Object

edu.ucdavis.rj.Inni

public class Inni
extends java.lang.Object

An Inni services on invocation from a specified group of InniOps. It consists of one or more possibly quantified arms; each arm specifies an operation or quantified group of operations and corresponding code to service the invocation. An Inni also allows an elseArm, which is executed if no invocation is selected for servicing.

Constructor Detail

Inni

public Inni(InniArmElse elseArm,
            InniArm firstArm,
            InniArm... restArms)

Create a new instance of an Inni. This is the general case (with an elseArm).

Parameters:

elseArm - The elseArm.

firstArm - The first arm.

restArms - Any other arms.

Inni

public Inni(InniArmElseafter elseafterArm,
            InniArm firstArm,
            InniArm... restArms)

Create a new instance of an Inni. This is the general case (with an elseafterArm).

Parameters:

elseafterArm - The elseafterArm.

firstArm - The first arm.

restArms - Any other arms.

Inni

public Inni(InniArm firstArm,
            InniArm... restArms)

Create a new instance of an Inni. This is the common case (without an elseArm or elseafterArm).

Parameters:

firstArm - The first arm.

restArms - Any other arms.

Method Detail

createInni

private void createInni(InniArmElse elseArm,
                        InniArmElseafter elseafterArm,
                        InniArm firstArm,
                        InniArm... restArms)

Common code called from constructors to create a new instance of an Inni.

Parameters:

elseArm - The elseArm.

elseafterArm - The elseafterArm.

firstArm - The first arm.

restArms - Any other arms.

oneInniArm

private void oneInniArm(java.util.ArrayList<InniArm> arms,
                        InniArm a,
                        int armCount)

Handle one abstract arm for this Inni.

Parameters:

arms - The list of arms to which to add this arm.

a - The arm.

armCount - The arm's number (0-based).

service

public BaseArmCode.Control service()

Service one invocation as specified by this Inni's arms by executing the codeBlock in the associated arm. If no invocation selected, delay the executing process until such an invocation arrives, unless this Inni has an elseArm, in which case execute the codeBlock in the elseArm.

Returns:

Value set within codeBlock indicating control flow to take.

execElseArmCode

private BaseArmCode.Control execElseArmCode(InniArmElseCode code)

Used for ElseArm and ElseafterArm. Execute the arm code, if it's not null. Returns the control info from the execution. N.B., these are executed w/o an Invocation!

Parameters:

code - The arm code.

Returns:

The control info.

gatherAndSortTimes

private java.util.ArrayList<Inni.TimeNode> gatherAndSortTimes(java.util.ArrayList<InniArm> arms)
