Method Summary | ||
---|---|---|
static ActiveDescriptorBuilder |
activeLink(Class<?> implementationClass)
This method creates an ActiveDescriptorBuilder , whose job it
is to create an unreified ActiveDescriptor . |
|
static Filter |
allFilter()
Returns a filter of type Descriptor that matches all descriptors |
|
static
|
createConstantDescriptor(T constant)
This creates a descriptor that will always return the given object. |
|
static IndexedFilter |
createContractFilter(String contract)
Returns an indexed filter that will return all descriptors that have contract as an advertised contract |
|
static DescriptorImpl |
createDescriptorFromClass(Class<?> clazz)
This returns a DescriptorImpl based on the given class. |
|
static IndexedFilter |
createNameAndContractFilter(String contract,
String name)
Returns an indexed filter that will return all descriptors that have the given name and given contract |
|
static IndexedFilter |
createNameFilter(String name)
Returns an indexed filter that will return all descriptors that have the given name |
|
static IndexedFilter |
createSpecificDescriptorFilter(ActiveDescriptor<?> descriptor)
This method creates a filter that will match one and only one descriptor. |
|
static DescriptorImpl |
deepCopyDescriptor(Descriptor copyMe)
Makes a deep copy of the incoming descriptor |
|
static void |
getMetadataValues(Annotation annotation,
Map<String,List<String>> metadata)
This is a helper method that gets the metadata values from the Metadata annotations found in an annotation. |
|
static DescriptorBuilder |
link(Class<?> implementationClass)
This method links an implementation class with a DescriptorBuilder , to
be used to further build the Descriptor . |
|
static DescriptorBuilder |
link(Class<?> implementationClass,
boolean addToContracts)
This method links an implementation class with a DescriptorBuilder , to
be used to further build the Descriptor |
|

be used to further build the Descriptor . |
|
static DescriptorBuilder |
link(String implementationClass,
boolean addToContracts)
This method links an implementation class with a DescriptorBuilder , to
be used to further build the Descriptor . |
