Constructor Detail

ConstructorParameterInjectionPoint

public ConstructorParameterInjectionPoint(@Nonnull
                                          Constructor<?> ctor,
                                          int pIndex)

Create a ConstructorParameterInjectionPoint that wraps the given parameter index for the given constructor, ctor.

Parameters:

ctor - The constructor to wrap

pIndex - The parameter index of this injection point within ctor's parameters

Throws:

NullPointerException - if ctor is null

IndexOutOfBoundsException - if pIndex is not a valid index into the constructor's parameters

Method Detail

getMember

@Nonnull
public Constructor<?> getMember()

Description copied from interface: InjectionPoint

Return the Member that produced this injection point. Synthetic injection points can have a null member.

Specified by:

getMember in interface InjectionPoint

Returns:

The constructor wrapped by this injection point

getParameterIndex

public int getParameterIndex()

Returns:

The parameter index of this injection point within the constructor'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()

Description copied from interface: InjectionPoint

Return the qualifier annotation added to the injection point. The returned annotation's type will have been annotated with Qualifier. If the injection point is not qualified, this will return null.

Specified by:

getQualifier in interface InjectionPoint

Returns:

Any qualifier applied to the injection point

getAttribute

@Nullable
public <A extends Annotation> A getAttribute(Class<A> atype)

Description copied from interface: InjectionPoint

Return the attribute of type A that is applied to the injection point. If the injection point does not have an attribute of type A, then null is returned.

Specified by:

getAttribute in interface InjectionPoint

Parameters:

atype - Attribute annotation type. It must be annotated with Attribute.

Returns:

The instance of A applied to the injection point, or null

getAttributes

@Nonnull
public Collection<Annotation> getAttributes()

Specified by:

getAttributes in interface InjectionPoint

Returns:

Immutable collection of attribute annotations (does not include the qualifier)

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
