public int getParameterIndex()

Returns:

The parameter index of this injection point within the setter's parameters

isNullable

public boolean isNullable()

Specified by:

isNullable in interface InjectionPoint

Returns:

True if this injection point accepts null values

getType

public Type getType()

Description copied from interface: InjectionPoint

Return the type required to satisfy the injection point.

Specified by:

getType in interface InjectionPoint

Returns:

The type of the injection point

getErasedType

public Class<?> getErasedType()

Specified by:

getErasedType in interface InjectionPoint

Returns:

Return the erased type of InjectionPoint.getType()

getQualifier

@Nullable
public Annotation getQualifier()
