Method Detail

createTypeId

public static <X> String createTypeId(javax.enterprise.inject.spi.AnnotatedType<X> annotatedType)

Generates a deterministic signature for an AnnotatedType. Two AnnotatedTypes that have the same annotations and underlying type will generate the same signature.

This can be used to create a unique bean id for a passivation capable bean that is added directly through the SPI.

Parameters:

annotatedType - The type to generate a signature for

Returns:

A string representation of the annotated type

createTypeId

public static <X> String createTypeId(Class<X> clazz,
                                      Collection<Annotation> annotations,
                                      Collection<javax.enterprise.inject.spi.AnnotatedMethod<? super X>> methods,
                                      Collection<javax.enterprise.inject.spi.AnnotatedField<? super X>> fields,
                                      Collection<javax.enterprise.inject.spi.AnnotatedConstructor<X>> constructors)

Generates a unique signature for a concrete class. Annotations are not read directly from the class, but are read from the annotations, methods, fields and constructors arguments

Parameters:

clazz - The java class type

annotations - Annotations present on the java class

methods - The AnnotatedMethods to include in the signature

fields - The AnnotatedFields to include in the signature

constructors - The AnnotatedConstructors to include in the signature

Returns:

A string representation of the type

createFieldId

public static <X> String createFieldId(javax.enterprise.inject.spi.AnnotatedField<X> field)

Generates a deterministic signature for an AnnotatedField. Two AnnotatedFields that have the same annotations and underlying field will generate the same signature.

createFieldId

public static <X> String createFieldId(Field field,
                                       Collection<Annotation> annotations)

Creates a deterministic signature for a Field.

Parameters:

field - The field to generate the signature for

annotations - The annotations to include in the signature

createCallableId

public static <X> String createCallableId(javax.enterprise.inject.spi.AnnotatedCallable<X> method)

Generates a deterministic signature for an AnnotatedCallable. Two AnnotatedCallables that have the same annotations and underlying callable will generate the same signature.

createMethodId

public static <X> String createMethodId(Method method,
                                        Set<Annotation> annotations,
                                        List<javax.enterprise.inject.spi.AnnotatedParameter<X>> parameters)

Creates a deterministic signature for a Method.

Parameters:

method - The method to generate the signature for

annotations - The annotations to include in the signature

parameters - The AnnotatedParameters to include in the signature

createConstructorId

public static <X> String createConstructorId(Constructor<X> constructor,
                                             Set<Annotation> annotations,
                                             List<javax.enterprise.inject.spi.AnnotatedParameter<X>> parameters)

Creates a deterministic signature for a Constructor.

Parameters:

constructor - The constructor to generate the signature for

annotations - The annotations to include in the signature

parameters - The AnnotatedParameters to include in the signature

createParameterListId

public static <X> String createParameterListId(List<javax.enterprise.inject.spi.AnnotatedParameter<X>> parameters)

Generates a unique string representation of a list of AnnotatedParameters.

createParameterId

public static <X> String createParameterId(javax.enterprise.inject.spi.AnnotatedParameter<X> annotatedParameter)

Creates a string representation of an AnnotatedParameter.

createParameterId

public static <X> String createParameterId(Type type,
                                           Set<Annotation> annotations)

Creates a string representation of a given type and set of annotations.

compareAnnotatedField

public static boolean compareAnnotatedField(javax.enterprise.inject.spi.AnnotatedField<?> f1,
                                            javax.enterprise.inject.spi.AnnotatedField<?> f2)

Compares AnnotatedFields for equality.

Two AnnotatedFields are considered equal if they have the same underlying field and annotations.

compareAnnotatedCallable

public static boolean compareAnnotatedCallable(javax.enterprise.inject.spi.AnnotatedCallable<?> m1,
                                               javax.enterprise.inject.spi.AnnotatedCallable<?> m2)

Compare AnnotatedCallables for equality.

Two AnnotatedCallables are considered equal if they have the same underlying callable and annotations.

compareAnnotatedTypes

public static boolean compareAnnotatedTypes(javax.enterprise.inject.spi.AnnotatedType<?> t1,
                                            javax.enterprise.inject.spi.AnnotatedType<?> t2)

Compares two AnnotatedTypes for equality.

Two AnnotatedTypes are considered equal if they have the same underlying type and annotations, and all members have the same annotations.
