Modifier and Type	Method and Description
protected List<Class<? extends Annotation>>	determineQualifiers(Annotation bindingAnnotation, Annotation... allAnnotations) Returns the qualifiers for this method, setting the Default qualifier if none are found Qualifiers can be either explicitly applied to the method, or implicit on account of being found in the annotation itself (for example @Plus would have a default binding scope of @PlusOperator)
protected boolean	isFromMatch(Constructor<?> constructor) Subclasses can override this template method with their own matching strategy
protected boolean	isFromMatch(Method method) Subclasses can override this template method with their own matching strategy
protected boolean	isToMatch(Method method) Subclasses can override this template method with their own matching strategy
<I,O> Map<ConverterKey<?,?>,Constructor<O>>	matchFromConstructors(Class<O> cls) Match constructors that can perform a from operation
<I,O> Map<ConverterKey<?,?>,Method>	matchFromMethods(Class<?> cls) Match methods that can perform a from operation

I - Input type

O - Output type

Parameters:

cls - The class being inspected

Returns:

The methods

matchFromConstructors

public <I,O> Map<ConverterKey<?,?>,Constructor<O>> matchFromConstructors(Class<O> cls)

Description copied from interface: ConverterProvider

Match constructors that can perform a from operation

Specified by:

matchFromConstructors in interface ConverterProvider

Type Parameters:

I - Input type

The constructors

matchFromMethods

public <I,O> Map<ConverterKey<?,?>,Method> matchFromMethods(Class<?> cls)

Description copied from interface: ConverterProvider

Match methods that can perform a from operation

Specified by:

matchFromMethods in interface ConverterProvider

Type Parameters:

I - Input type

O - Output type

Parameters:

cls - The class being inspected

Returns:

The methods

isToMatch

protected boolean isToMatch(Method method)

Subclasses can override this template method with their own matching strategy

Parameters:

method - The method to be determined

Returns:

True if match

isFromMatch

protected boolean isFromMatch(Constructor<?> constructor)

Subclasses can override this template method with their own matching strategy

Parameters:

constructor - The constructor to be determined

Returns:

True if match

isFromMatch

protected boolean isFromMatch(Method method)

Subclasses can override this template method with their own matching strategy

Parameters:

method - The method to be determined

Returns:

True if match

determineQualifiers

protected List<Class<? extends Annotation>> determineQualifiers(Annotation bindingAnnotation,
                                                                Annotation... allAnnotations)

Returns the qualifiers for this method, setting the Default qualifier if none are found Qualifiers can be either explicitly applied to the method, or implicit on account of being found in the annotation itself (for example @Plus would have a default binding scope of @PlusOperator)

Parameters:

bindingAnnotation - The Annotation for the binding to check if it specifies a binding scope.

allAnnotations - Array of Annotations on the target method to check if they specify a scope

Returns:

True if method can be matched for the given scope
