- Creates a property value based on the com.aendvari.cerberus.component.descriptor.MultiPartValue and the
attributes defined in the com.aendvari.cerberus.component.descriptor.ComponentDescriptor.
dependenciesAvailable
private boolean dependenciesAvailable(com.aendvari.cerberus.component.descriptor.ComponentDescriptor descriptor, com.aendvari.cerberus.component.descriptor.MultiPartValue value)
- Checks that the attributes used in the supplied com.aendvari.cerberus.component.descriptor.MultiPartValue
have been defined in the com.aendvari.cerberus.component.descriptor.ComponentDescriptor.
assembleComponentAttributes
private void assembleComponentAttributes(com.aendvari.cerberus.component.descriptor.ComponentDefinition definition, com.aendvari.cerberus.component.descriptor.ComponentInstance instance, com.aendvari.cerberus.component.descriptor.ComponentDescriptor descriptor) throws AssemblyException
- Creates and stores attribute values in the com.aendvari.cerberus.component.descriptor.ComponentDescriptor.
Any attributes referenced by the com.aendvari.cerberus.component.descriptor.MultiPartValue are taken from the other
attributes in the com.aendvari.cerberus.component.descriptor.ComponentDescriptor. Those attributes must have their
values specified before being used by another attribute.
mapMessage
private void mapMessage(com.aendvari.cerberus.component.descriptor.ComponentDescriptor descriptor, com.aendvari.cerberus.component.descriptor.ComponentMessage definitionMessage, com.aendvari.cerberus.component.descriptor.ComponentMessage resolveMessage, java.util.Collection unresolved)
