Method Detail

getRequiredType

public Type getRequiredType()
Description copied from interface: Injectee
This is the required type of the injectee. The object that is injected into this point must be type-safe with regards to this type

Specified by:
getRequiredType in interface Injectee
Returns:
The type that this injectee is expecting. Any object injected into this injection point must be type-safe with regards to this type

getRequiredQualifiers

public Set<Annotation> getRequiredQualifiers()
Description copied from interface: Injectee
This is the set of required qualifiers for this injectee. All of these qualifiers must be present on the implementation class of the object that is injected into this injectee. Note that the fields of the annotation must also match

Specified by:
getRequiredQualifiers in interface Injectee
Returns:
Will not return null, but may return an empty set. The set of all qualifiers that must match.

getPosition

public int getPosition()
Description copied from interface: Injectee
If this Injectee is a constructor or method parameter, this will return the index of the parameter. If this Injectee is a field, this will return -1

Specified by:
getPosition in interface Injectee
Returns:
the position of the parameter, or -1 if this is a field

getInjecteeClass

public Class<?> getInjecteeClass()
Description copied from interface: Injectee
Returns the parent class for this injectee. This is the class of the object that will be injected into.

Specified by:
getInjecteeClass in interface Injectee
Returns:
The class of the object that will be injected into

getParent

public AnnotatedElement getParent()
Description copied from interface: Injectee
If this Injectee is in a constructor this will return the constructor being injected into. If this Injectee is in a method this will return the method being injected into. If this injectee represents a field, this will return the field being injected into

Specified by:
getParent in interface Injectee
Returns:
The parent of the injectee

isOptional

public boolean isOptional()
Description copied from interface: Injectee
This method returns true if this injection point is annotated with VOptional. In this case if there is no definition for the injection point in the system it is allowable for the system to merely return null

Specified by:
isOptional in interface Injectee
Returns:
true if the injection point is annotated with VOptional, false otherwise

isSelf

public boolean isSelf()
Description copied from interface: Injectee
This method returns true if this injection point is annotated with VSelf. In this case the required type must have a raw class of ActiveDescriptor, isOptional must be false and the set of required qualifiers must be empty

Specified by:
isSelf in interface Injectee
Returns:
true if the injection point is annotated with VSelf, false otherwise

toString

public String toString()
Overrides:
toString in class Object
