Class DefaultRuntimePropertiesPluginImpl

java.lang.Object

org.azyva.dragom.execcontext.plugin.impl.DefaultRuntimePropertiesPluginImpl

All Implemented Interfaces:

org.azyva.dragom.execcontext.plugin.ExecContextPlugin, org.azyva.dragom.execcontext.plugin.RuntimePropertiesPlugin

public class DefaultRuntimePropertiesPluginImpl
extends Object
implements org.azyva.dragom.execcontext.plugin.RuntimePropertiesPlugin

This default implementation of RuntimePropertiesPlugin considers the following sources for the properties, in precedence order (the first one that provides a requested property is used):

• Transient data within the ExecContext (ExecContext.getTransientData(java.lang.String)) having the prefix "runtime-property"
• Tool properties (ToolLifeCycleExecContext.getToolProperty(java.lang.String)) having the prefix "runtime-property", if the ExecContext implements ToolLifeCycleExecContext
• ExecContext properties (ExecContext.getProperty(java.lang.String)) having the prefix "runtime-property"
• ExecContext initialization properties (ExecContext.getInitProperty(java.lang.String)) having the prefix "runtime-property"
• System properties (System.getProperty) having the prefix "org.azyva.dragom.runtime-property"
• Node properties within the Model (@link Node#getProperty}.

The name of the property following the prefix is the the NodePath of the node with "." separating the nodes and with the last token being the actual property name. For example the following tool initialization property:

org.azyva.dragom.runtime-property.Domain1.app-a.MY_PROPERTY=my-value

defines a property MY_PROPERTY associated with the module Domain1/app-a whose value is my-value.

Property inheritance is considered, meaning that a property defined for a parent Node is used if the property is not defined specifically for the specified Node. For all sources except the Model this is done by sequentially removing Node's from the end of the NodePath. For the Model, this is automatically done by the fact that the property is requested on the Node specified by the Node.

A property being defined only for a specific Node is not explicitly supported, also the Model may support this.

Properties are always set as transient data (ExecContext.setTransientData(java.lang.String, java.lang.Object)).
