AdvisorDef (Tapestry API - 5.8.6)

All Known Subinterfaces:

AdvisorDef2

All Known Implementing Classes:

AdvisorDefImpl
```
public interface AdvisorDef
```
Definition of a service advisor, which (by default) is derived from a service advisor method. Service advisor methods are static or instance methods on module classes prefixed with "advise". When a service is realized, a list of matching AdvisorDefs is generated, then ordered, and from each a ServiceAdvisor is obtained and invoked. Note: service decorators (via DecoratorDef are applied around the interceptor generated via service advisors, (for compatibility with Tapestry 5.0). In general, you should use service decoration or service advice, not both.

Since:

5.1.0.0

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`ServiceAdvisor`	`createAdvisor(ModuleBuilderSource moduleSource, ServiceResources resources)`	Creates an object that can provide the service advice (in the default case, by invoking the advise method on the module class or instance).
`java.lang.String`	`getAdvisorId()`	Returns the id of the advisor, which is derived from the advisor method name.
`java.lang.String[]`	`getConstraints()`	Returns ordering constraints for this advisor, to order it relative to other advisors.
`boolean`	`matches(ServiceDef serviceDef)`	Used to determine which services may be advised.

- Method Detail
  - getAdvisorId
```
java.lang.String getAdvisorId()
```
    Returns the id of the advisor, which is derived from the advisor method name.
  - getConstraints
```
java.lang.String[] getConstraints()
```
    Returns ordering constraints for this advisor, to order it relative to other advisors.
    
    Returns:
    
    zero or more constraint strings
  - createAdvisor
```
ServiceAdvisor createAdvisor(ModuleBuilderSource moduleSource,
                             ServiceResources resources)
```
    Creates an object that can provide the service advice (in the default case, by invoking the advise method on the module class or instance).
    
    Parameters:
    
    moduleSource - used to obtain the module instance
    
    resources - used to provide injections into the advise method
    
    Returns:
    
    advisor
  - matches
```
boolean matches(ServiceDef serviceDef)
```
    Used to determine which services may be advised. When advising a service, first the advisors that target the service are identified, then ordering occurs, then the ServiceAdvisors are obtained and invoked.
    
    Parameters:
    
    serviceDef - identifies a service that may be advised
    
    Returns:
    
    true if this advisor applies to the service
