Enum Constant Summary

Enum Constants

Enum Constant	Description
ALL_RUNTIME	All annotations marked as RetentionPolicy.RUNTIME will qualify, which implicitly will also cover all usages of EXPLICIT.
ALLOW_LISTED	A call to InterceptorCreator.allowListedAnnotationTypes() will be used to determine which annotations qualify.
BLENDED	Applies a blend of EXPLICIT and CUSTOM to determine which annotations qualify (i.e., if the annotation is not explicitly marked, then a call is still issued to InterceptorCreator.isAllowListed(io.helidon.common.types.TypeName).
CUSTOM	A call to InterceptorCreator.isAllowListed(io.helidon.common.types.TypeName) will be used on a case-by-case basis to check which annotation types qualify.
EXPLICIT	Meta-annotation based.
NONE	No annotations will qualify in triggering interceptor creation.

Method Summary

Modifier and Type	Method	Description
static InterceptorCreator.Strategy	valueOf(String name)	Returns the enum constant of this class with the specified name.
static InterceptorCreator.Strategy[]	values()	Returns an array containing the constants of this enum class, in the order they are declared.

Enum Constant Details

EXPLICIT

public static final InterceptorCreator.Strategy EXPLICIT

Meta-annotation based. Only annotations annotated with InterceptedTrigger will qualify.

ALL_RUNTIME

public static final InterceptorCreator.Strategy ALL_RUNTIME

All annotations marked as RetentionPolicy.RUNTIME will qualify, which implicitly will also cover all usages of EXPLICIT.

ALLOW_LISTED

public static final InterceptorCreator.Strategy ALLOW_LISTED

A call to InterceptorCreator.allowListedAnnotationTypes() will be used to determine which annotations qualify. The implementation may then cache this result internally for optimal processing.

CUSTOM

public static final InterceptorCreator.Strategy CUSTOM

A call to InterceptorCreator.isAllowListed(io.helidon.common.types.TypeName) will be used on a case-by-case basis to check which annotation types qualify.

NONE

public static final InterceptorCreator.Strategy NONE

No annotations will qualify in triggering interceptor creation.

BLENDED

public static final InterceptorCreator.Strategy BLENDED

Applies a blend of EXPLICIT and CUSTOM to determine which annotations qualify (i.e., if the annotation is not explicitly marked, then a call is still issued to InterceptorCreator.isAllowListed(io.helidon.common.types.TypeName). This strategy is typically the default strategy type in use.

Method Details

values

public static InterceptorCreator.Strategy[] values()

Returns an array containing the constants of this enum class, in the order they are declared.

Returns:

an array containing the constants of this enum class, in the order they are declared

valueOf

public static InterceptorCreator.Strategy valueOf(String name)

Returns the enum constant of this class with the specified name. The string must match exactly an identifier used to declare an enum constant in this class. (Extraneous whitespace characters are not permitted.)

Parameters:

name - the name of the enum constant to be returned.

Returns:

the enum constant with the specified name

Throws:

IllegalArgumentException - if this enum class has no constant with the specified name

NullPointerException - if the argument is null
