public abstract class EnterpriseConfigurationObjectImpl

extends OpenEaiObject

The parent class for all of our 'configuration' objects. The reason we add this layer to our configuration strategy is so all our framework components don't have to be 'xml aware'. This way we can abstract that requirement and if we ever decide to use anything besides or in addition to XML for configuration information, we just have to change this layer and not our framework components per se.

Constructor

Method Detail

setName

public void setName(java.lang.String name)

Sets the object name associated to the configuration object being built. Specifically, this is the "name" attribute that all configuration Elements have as defined in the Deployment.dtd document. This allows AppConfig to store the pre-configured objects that get initialized using these configuration objects by name and application developers to retrieve them by name.

getName

public java.lang.String getName()

Returns the object name associated to the configuration object being built. Specifically, this is the "name" attribute that all configuration Elements have as defined in the Deployment.dtd document. This allows AppConfig to store the pre-configured objects that get initialized using these configuration objects by name and application developers to retrieve them by name.

Returns:

String the name of the configuration object (and thus the actual foundation object) specified in the "name" attribute associated to each configuration Element in the deployment document.

setAppName

public final void setAppName(java.lang.String name)

Sets the Application name associated to this configuration object (and the actual object that will be initialized with this configuration object).

Overrides:

setAppName in class OpenEaiObject

getAppName

public final java.lang.String getAppName()

Returns the Application name associated to this configuration object (and the actual object that will be initialized with this configuration object).

Overrides:

getAppName in class OpenEaiObject

Returns:

String the name of the application to which this object will belong.

setType

public void setType(java.lang.String type)

Sets the type of Configuration object that this is. Types so far include:

• MessageObjectConfig
• CommandConfig
• ConsumerConfig
• ProducerConfig
• DbConnectionPoolConfig
• AppConfig
• PropertyConfig
• ThreadPoolConfig

getType

public java.lang.String getType()

Returns the type of Configuration object that this is. Types so far include:

• MessageObjectConfig
• CommandConfig
• ConsumerConfig
• ProducerConfig
• DbConnectionPoolConfig
• AppConfig
• PropertyConfig
• ThreadPoolConfig

Returns:

String type.

setValidation

public final void setValidation(boolean validate)

This method, along with 'getValidation' are used to determine if the XML configuration document used to configure an application will be validated or not. There are currently no uses of this method therefore all deployment/configuration XML document validation is always false. These methods may be removed altogether in the future because at this point there is really no way to turn validation on for these deployment/configuration documents. Additionally, there may not be any reason to do so. Validation is typically performed when the document is being filled out. There are times when it is necessary to allow an invalid document to exist for testing purposes etc.

getValidation

public final boolean getValidation()

Returns a boolean indicating whether or not XML document validation for the deployment documents is turned on or not. Currently, XML validation is always 'false'.

Returns:

boolean true to turn XML validation on false to turn it off.

setConfigDoc

public final void setConfigDoc(org.jdom.Document configDoc)

Sets the deployment/configuration document that is associated to this Configuration object. This is determined when AppConifg is initialized. Then it parses that document and calls this method so the object will have a reference to the document it needs to configure itself.

getConfigDoc

public final org.jdom.Document getConfigDoc()

Returns the deployment/configuration document that is associated to this Configuration object. This is determined when AppConifg is initialized. This is what the object uses to determine how it needs to be configured.

Returns:

Document JDOM Document.

addProperty

public final void addProperty(java.lang.String key,
                              java.lang.String value)

Adds a general property (name/value pair) to this object's inherited Properties object. Many Configuration objects use general properties in addition to specific instance variables in the object to specify the configuration informatin for an object. It's up to the implementor of the EnterpriseConfigurationObject (i.e. ProducerConfig) and the foundation component (i.e. PointToPointProducer) to determine what will be general properties and what will be specified via specific instance variables and the corresponding getter/setter methods.

Generally, "simple" configuration elements should be considered for use as a general properties and complex configuration elements that have an associated Java object should be specific getter/setter methods in the configuration object.

getElementByAttributeValue

public final org.jdom.Element getElementByAttributeValue(org.jdom.Element e,
                                                         java.lang.String attrValue)

getConfigElementByAttributeValue

public final org.jdom.Element getConfigElementByAttributeValue(java.lang.String value,
                                                               java.lang.String attributeName)
