Class DomainInfo

java.lang.Object

psdi.mbo.DomainInfo

All Implemented Interfaces:

java.io.Serializable

Direct Known Subclasses:

NewDomainInfo

public abstract class DomainInfo
extends java.lang.Object
implements java.io.Serializable

Base class used for all domain info classes. This is used to capture all the information that is need to be used by a validation domain. The class is created by the data dictionary and is held in memory until needed. This technique is used to speed up the instanciation of the validation domains. All implementatins of a domain info must implement the method init() which has been declared abstract.

Construct giving name

Method Detail

init

public static java.util.Vector init(java.sql.Connection con,
                    java.lang.String sqlExpr)

All subclasses need to override this method. The method will initilize all the domains of its type and return them in a vector. For example, a ValueListDomainInfo init() will return all the valuelistdomaininfo obects that need to be instanciated.

getName

public java.lang.String getName()

Get the name of the domain

setNeverCache

public void setNeverCache(boolean neverCacheParam)

Setter method for Never Cache

Parameters:

neverCacheParam - Never Cache value

getNeverCache

public boolean getNeverCache()

Getter method for Never Cache

Returns:

Is this domain never cached

getDomainObject

public abstract MboValueListener getDomainObject(MboValue mbv)

Return an object that will actually perform the validation

toString

public java.lang.String toString()

Dump the domain info to a string for debugging purposes

Overrides:

toString in class java.lang.Object

getDetail

public java.lang.Object getDetail(java.lang.Object[] signature)

contains

public boolean contains(java.lang.String site,
               java.lang.String org)

Check if a site level or org level domain values exists as detail.

Parameters:

site -

org -

Returns:

getKey

public static final java.lang.String getKey(java.lang.String site,
                      java.lang.String org)

setDetail

public void setDetail(java.lang.String site,
             java.lang.String org,
             java.lang.Object detail)

needToConsiderSiteOrg

public boolean needToConsiderSiteOrg()

Returns a true if there are any site or org specific values in this domain. If there are none, site org related where clause are not need to present in the selction of the domain values.

Returns:

getSignature

public java.lang.Object[] getSignature(MboValue value)
                                throws MXException,
                                       java.rmi.RemoteException

Get the signature of the passed in MboValue. The signature can be cached by the domain object. If the signature is different than its previous signature, the domain value will need to be reset. If null is returned, that means the signature does not need to be fetched because the domain value once decided will not need to be reset.

Parameters:

mbo -

Returns:

Throws:

MXException

java.rmi.RemoteException

canSignatureChangeAfterInit

public boolean canSignatureChangeAfterInit(MboValue value)

Can signature of the object be modified after the MBO value is initialized. If the factor to contribute to the signature will never change, this returns false.

Parameters:

value -

Returns:

isDifferentSignature

public boolean isDifferentSignature(java.lang.Object[] lastSignature,
                           java.lang.Object[] newSignature)

Compare the two signatures. True if they are considered different.

Parameters:

lastSignature -

newSignature -

Returns:
