Constructor Detail

SwitchComponent

public SwitchComponent(AssemblyLine parent,
                       java.lang.String name,
                       BranchingConfig config)
                throws java.lang.Exception

Constructor for the BranchingComponent object

Parameters:

parent - The AssemblyLine that contains this SwitchComponent

name - The name of this SwitchComponent

config - The configuration for this SwitchComponent

Throws:

java.lang.Exception

Method Detail

initialize

public void initialize()
                throws java.lang.Exception

Initializes this SwitchComponent

Overrides:

initialize in class BranchingComponent

Throws:

java.lang.Exception - Not really, but subclasses may throw Exceptions

getType

public int getType()

Gets the type attribute of the BranchingComponent object

Overrides:

getType in class BranchingComponent

Returns:

The type value

willExecute

public boolean willExecute(Entry work)
                    throws java.lang.Exception

Return true/false if this component should be executed. Return true if this is a SWITCH, or if the expression in this CASE matches the expression in the containing SWITCH

Overrides:

willExecute in class BranchingComponent

Parameters:

work - The work Entry

Returns:

see above

Throws:

java.lang.Exception - Any Exception that might be thrown

add

public void add(Entry meta)
         throws java.lang.Exception

This method does nothing

Overrides:

add in class BranchingComponent

Parameters:

meta - parameter

Throws:

java.lang.Exception - if problem occurs

getLastExpression

public java.lang.String getLastExpression()

Returns the value from the last evaluated expression. This is used by the CASE components when they compare to their own values.

getParentSwitch

public SwitchComponent getParentSwitch()

Returns the SWITCH component to which this CASE belongs.

getCaseExecuted

public boolean getCaseExecuted()

Returns true if any contained CASE component executed this cycle

Returns:

true if any contained CASE component executed this cycle

getCaseExecutedBy

public java.lang.String getCaseExecutedBy()

Returns the name of the CASE component that executed this cycle

Returns:

the name of the CASE component that executed this cycle

setCaseExecutedBy

public void setCaseExecutedBy(java.lang.String name)

Sets the name of the CASE component that executed this cycle (called by CASE components)

Parameters:

name - The name of the CASE component that executed this cycle
