      org.apache.synapse.deployers.AbstractSynapseArtifactDeployer

All Implemented Interfaces:

Deployer

public abstract class AbstractSynapseArtifactDeployer
extends AbstractDeployer

Implements the generic logic for the synapse artifact deployment and provide a deployment framework for the synapse.

Any synapse artifact which requires the hot deployment or hot update features should extend this and just needs to concentrate on the deployment logic. By default setting the file extension and directory dynamically is not supported.

Method Detail

init

public void init(ConfigurationContext configCtx)

Initializes the Synapse artifact deployment

Parameters:

configCtx - Axis2 ConfigurationContext

deploy

public void deploy(DeploymentFileData deploymentFileData)
            throws DeploymentException

This method is called by the axis2 deployment framework and it performs a synapse artifact specific yet common across all the artifacts, set of tasks and delegate the actual deployment to the respective artifact deployers.

Specified by:

deploy in interface Deployer

Overrides:

deploy in class AbstractDeployer

Parameters:

deploymentFileData - file to be used for the deployment

Throws:

DeploymentException - in-case of an error in deploying the file

See Also:

deploySynapseArtifact(org.apache.axiom.om.OMElement, String,java.util.Properties)

undeploy

public void undeploy(String fileName)
              throws DeploymentException

This is the method called by the axis2 framework for undeployment of the artifacts. As in the deploy case this performs some common tasks across all the synapse artifacts and fall back to the artifact specific logic of undeployment.

Specified by:

undeploy in interface Deployer

Overrides:

undeploy in class AbstractDeployer

Parameters:

fileName - file describing the artifact to be undeployed

Throws:

DeploymentException - in case of an error in undeployment

See Also:

undeploySynapseArtifact( String)

setDirectory

public void setDirectory(String directory)

setExtension

public void setExtension(String extension)

deploySynapseArtifact

public abstract String deploySynapseArtifact(OMElement artifactConfig,
                                             String fileName,
                                             Properties properties)

All synapse artifact deployers MUST implement this method and it handles artifact specific deployment tasks of those artifacts.

Parameters:

artifactConfig - built element representing the artifact to be deployed loaded from the file

fileName - file name from which this artifact is being loaded

properties - Properties associated with the artifact

Returns:

String artifact name created by the deployment task

See Also:

deploy( org.apache.axis2.deployment.repository.util.DeploymentFileData)

updateSynapseArtifact

public abstract String updateSynapseArtifact(OMElement artifactConfig,
                                             String fileName,
                                             String existingArtifactName,
                                             Properties properties)

All synapse artifact deployers MUST implement this method and it handles artifact specific update tasks of those artifacts.

Parameters:

artifactConfig - built element representing the artifact to be deployed loaded from the file

fileName - file name from which this artifact is being loaded

existingArtifactName - name of the artifact that was being deployed using the updated file

properties - bag of properties with the additional information

Returns:

String artifact name created by the update task

undeploySynapseArtifact

public abstract void undeploySynapseArtifact(String artifactName)

All synapse artifact deployers MUST implement this method and it handles artifact specific undeployment tasks of those artifacts.

Parameters:

artifactName - name of the artifact to be undeployed

See Also:

undeploy(String)

restoreSynapseArtifact
