extends AssetReferenceable

ConnectionProperties is an object that contains the properties needed to create and initialise a connector to access a specific data assets. The properties for ConnectionProperties are defined in model 0201. They include the following options for connector name:

• guid - Globally unique identifier for the connection.
• url - URL of the connection definition in the metadata repository. This URL can be stored as a property in another entity to create an explicit link to this connection.
• qualifiedName - The official (unique) name for the connection. This is often defined by the IT systems management organization and should be used (when available) on audit logs and error messages. The qualifiedName is defined in the 0010 model as part of Referenceable.
• displayName - A consumable name for the connection. Often a shortened form of the qualifiedName for use on user interfaces and messages. The displayName should be only be used for audit logs and error messages if the qualifiedName is not set.

Either the guid, qualifiedName or displayName can be used to specify the name for a connection. Other properties for the connection include:

• type - information about the TypeDef for Connection
• description - A full description of the connection covering details of the assets it connects to along with usage and versioning information.
• additionalProperties - Any additional properties associated with the connection.
• securedProperties - Protected properties for secure log on by connector to back end server. These are protected properties that can only be retrieved by privileged connector code.
• connectorType - Properties that describe the connector type for the connector.
• endpoint - Properties that describe the server endpoint where the connector will retrieve the assets.

Field Detail

connectionBean

protected Connection connectionBean

Constructor Detail

ConnectionProperties

public ConnectionProperties(Connection connectionBean)

Bean constructor

Parameters:

connectionBean - bean containing the properties

ConnectionProperties

public ConnectionProperties(AssetDescriptor parentAsset,
                            Connection connectionBean)

Bean constructor with parent asset

Parameters:

parentAsset - description of the asset that this connection is attached to.

connectionBean - bean containing the properties

ConnectionProperties

public ConnectionProperties(ConnectionProperties templateConnection)

Copy/clone Constructor to return a copy of a connection object that is not connected to an asset.

Parameters:

templateConnection - Connection to copy

ConnectionProperties

public ConnectionProperties(AssetDescriptor parentAsset,
                            ConnectionProperties templateConnection)

Copy/clone Constructor to return a copy of a connection object that is connected to an asset.

Parameters:

parentAsset - description of the asset that this connection is attached to.

templateConnection - template object to copy.

Method Detail

getConnectionBean

protected Connection getConnectionBean()

Return the bean with all of the properties.

Returns:

connection bean

getDisplayName

public String getDisplayName()

Returns the stored display name property for the connection. Null means no displayName is available.

Returns:

displayName

getConnectionName

public String getConnectionName()

Returns a formatted string with the connection name. It is used in formatting error messages for the exceptions thrown by consuming components. It is extremely cautious because most of the exceptions are reporting a malformed connection object so who knows what else is wrong with it. Within the connection are 2 possible properties that could contain the connection name: ** qualifiedName - this is a uniqueName and should be there ** displayName - shorter simpler name but may not be unique - so may not identify the connection in error This method inspects these properties and builds up a string to represent the connection name

Returns:

connection name

getDescription

public String getDescription()

Returns the stored description property for the connection. If no description is provided then null is returned.

Returns:

description

getConnectorType

public ConnectorTypeProperties getConnectorType()

Returns a copy of the properties for this connection's connector type. A null means there is no connection type.

Returns:

connector type for the connection

getEndpoint

public EndpointProperties getEndpoint()

Returns a copy of the properties for this connection's endpoint. Null means no endpoint information available.

Returns:

endpoint for the connection

getSecuredProperties

protected AdditionalProperties getSecuredProperties()

Return a copy of the secured properties. Null means no secured properties are available. This method is protected so only OCF (or subclasses) can access them. When Connector is passed to calling OMAS, the secured properties are not available.

Returns:

secured properties typically user credentials for the connection

toString

public String toString()

Standard toString method.

Overrides:

toString in class AssetReferenceable

Returns:

print out of variables in a JSON-style

equals

public boolean equals(Object objectToCompare)

Compare the values of the supplied object with those stored in the current object.

Overrides:

equals in class AssetReferenceable

Parameters:

objectToCompare - supplied object

Returns:

boolean result of comparison
