org.gcube.common.core.contexts.GCUBEPortTypeContext

Direct Known Subclasses:

GCUBEStatefulPortTypeContext

public abstract class GCUBEPortTypeContext
extends GCUBEContext

Partial implementation of contexts for port-types.

If useful, the creation of a port-type context may be cached, e.g. using the pattern illustrated for GCUBEServiceContext.

Constructor Detail

GCUBEPortTypeContext

public GCUBEPortTypeContext()

Method Detail

getEPR

public org.apache.axis.message.addressing.EndpointReferenceType getEPR()
                                                                throws Exception

Returns an (unqualified) EPR to the port-type.

Returns:

the EPR.

Throws:

Exception - if the EPR could not be derived.

getName

public String getName()

Returns a name for the port-type to use in log entries. By default, it derives a name from the JNDI name of the port-type.

Overrides:

getName in class GCUBEContext

Returns:

the name.

See Also:

getJNDIName()

getProperty

public Object getProperty(String prop,
                 boolean... required)
                   throws RuntimeException

Resolve a configuration property against the naming service. Resolution is relative to the root JNDI context of the naming service and the JNDI name associated with the context.

Overrides:

getProperty in class GCUBEContext

Parameters:

prop - the property.

required - (optional) true if the property is required, false or omitted if property is optional. The only implication is a different handling of failure and logging. Failure in resolving optional properties results in a runtime exception and fatal log entry, whereas failure in resolving optional properties results in a null result and warning in the log.

Returns:

the value of the property, or null if the property was optional and could not be resolved.

Throws:

RuntimeException - if the property is required but cannot be resolved.

getDeploymentDescriptor

public org.apache.axis.deployment.wsdd.WSDDService getDeploymentDescriptor()

Returns the deployment descriptor of the port-type.

Returns:

the deployment descriptor.

getSecurityDescriptor

public org.globus.wsrf.impl.security.descriptor.ServiceSecurityDescriptor getSecurityDescriptor()

Returns the security descriptor of the port-type.

Returns:

the security descriptor.

getFile

public File getFile(String path,
           boolean... writeMode)

Gives read or write access to a File. Write access induces backups and read access relies on backups to recover from failures.

Overrides:

getFile in class GCUBEContext

Parameters:

path - the file path.

writeMode - (optional) the access mode, true for write access and false for read access (default).

Returns:

the file.

getPersistentFile

public File getPersistentFile(String path,
                     boolean... writeMode)
                       throws IllegalArgumentException

Gives read or write access to a File that will persist across redployments of the Running Instance.

Parameters:

path - the file path.

writeMode - (optional) the access mode, true for write access and false for read access (default).

Returns:

the file.

Throws:

IllegalArgumentException - if access is in write mode and the path is to a folder.

See Also:

GCUBEServiceContext.getPersistentFile(String, boolean...)

getJNDIName

public abstract String getJNDIName()

Return the name of the port-type in the JNDI configuration

Returns:

the JNDI name.

getNamespace

public abstract String getNamespace()

Returns the namespace of the port-type.

Returns:

the namespace.

getServiceContext

public abstract GCUBEServiceContext getServiceContext()

Returns the name of the service of the port-type.

Returns:

the name.

onInitialisation

protected void onInitialisation()
                         throws Exception

Invoked when the Running Instance has completed initialisation. If needed, override in accordance with service semantics.

Throws:

Exception - if the callback did not complete successfully.

onReady

protected void onReady()
                throws Exception

Invoked when the Running Instance is ready to operate. If needed, override in accordance with service semantics.

Throws:

Exception - if the callback did not complete successfully.

onUpdate

protected void onUpdate()
                 throws Exception

Invoked when the Runnning Instance is updated. If needed, override in accordance with service semantics.

Throws:

Exception - if the callback did not complete successfully.

onStateChange

protected void onStateChange()
                      throws Exception

Invoked upon a change to the RI's stateful resources, if any. If needed, override in accordance with service semantics.

Throws:

Exception - if the callback did not complete successfully.

onFailure

protected void onFailure()
                  throws Exception

Invoked when the Running Instance fails. If needed, override in accordance with service semantics.

Throws:

Exception - if the callback did not complete successfully.
