Class RAFetchRegister

java.lang.Object
  raar.register.RARegister
      raar.register.RAFetchRegister

All Implemented Interfaces:

java.io.Serializable

public class RAFetchRegister
extends RARegister
implements java.io.Serializable

This class defines a register for which you can only get values that already exist, and which can be fetched COMPLETELY from an other register. In RAAR it is used to model process outputs. Once you have set the keys which should be in the register, it locks up and cannot be changed except using the copyFromRegister method.

Constructor Detail

RAFetchRegister

public RAFetchRegister()

Construct a new register

RAFetchRegister

public RAFetchRegister(java.util.Vector names)

Construct a register which can contain values for keys (Strings) defined in the Vector. You can do this only once (i.e. calling setNameVector no longer is allowed).

Method Detail

setNameVector

public void setNameVector(java.util.Vector names)

Set the keys this register can contain. You can do this only once! Will throw a dirty exception (division by zero) when an attempt is made anyway.

add

public void add(java.lang.String name,
                RADataType dt)
         throws RAException

This method is not supported; you may not add any new keys! Throws an exception when called.

Overrides:

add in class RARegister

Throws:

RAException

set

public void set(java.lang.String name,
                RADataType dt)
         throws RAException

This method is not supported; you may never set a new value. Throws an exception when called.

Overrides:

set in class RARegister

Throws:

RAException

copyFromRegister

public void copyFromRegister(RARegister r)
                      throws RAException

Copy values from the specified Register into this Register, for all the keys (names) that exist in this Register. Throws exception if any of the names does not exist in r.

Throws:

RAException

clearRegister

public void clearRegister(RARegister r)
                   throws RAException

Replace the complete content by null. I.e. every key requested will have an associated null output value. Also if you specify a register as an argument, in that register the values for keys also in this register will be set to null. Now read that again and try to understand :-)

Throws:

RAException

toString

public java.lang.String toString()

Overrides:

toString in class RARegister
