RuntimeTypeProviderLegacyImpl

public RuntimeTypeProviderLegacyImpl(CelOptions celOptions,
                                     CelValueProvider valueProvider,
                                     CelDescriptorPool celDescriptorPool,

Method Detail

createMessage

public java.lang.Object createMessage(java.lang.String messageName,
                                      java.util.Map<java.lang.String,java.lang.Object> values)

Description copied from interface: MessageProvider

Create a message based on the fully qualified message name and field-value mapping.

Specified by:

createMessage in interface MessageProvider

selectField

public java.lang.Object selectField(java.lang.Object message,
                                    java.lang.String fieldName)

Description copied from interface: MessageProvider

Select field from message.

Specified by:

selectField in interface MessageProvider

hasField

public java.lang.Object hasField(java.lang.Object message,
                                 java.lang.String fieldName)

Description copied from interface: MessageProvider

Check whether a field is set on message.

Specified by:

hasField in interface MessageProvider

adapt

public java.lang.Object adapt(java.lang.Object message)

Description copied from interface: MessageProvider

Adapt object to its message value with source location metadata on failure .

Specified by:

adapt in interface MessageProvider

resolveObjectType

public Value resolveObjectType(java.lang.Object obj,
                               Value checkedTypeValue)

Description copied from interface: TypeResolver

Resolve the CEL type of the obj, using the checkedTypeValue as hint for type disambiguation.

The checkedTypeValue indicates the statically determined type of the object at check-time. Often, the check-time and runtime phases agree, but there are cases where the runtime type is ambiguous, as is the case when a Long value is supplied as this could either be an int, uint, or enum type.

Type resolution is biased toward the runtime value type, given the dynamically typed nature of CEL.

Specified by:

resolveObjectType in interface TypeResolver

adaptType

public Value adaptType(CelType type)

Description copied from interface: TypeResolver

Adapt the check-time type instance to a runtime Value.

When the checked type does not have a runtime equivalent, e.g. Type#DYN, the return value will be null.

Specified by:

adaptType in interface TypeResolver

adaptType

public @Nullable Value adaptType(@Nullable Type type)

Description copied from interface: TypeResolver

Adapt the check-time type instance to a runtime Value.

When the checked type does not have a runtime equivalent, e.g. Type#DYN, the return value will be null.

Specified by:

adaptType in interface TypeResolver
