The TypeResolver determines the CEL type of Java-native values and assists with adapting check-time types to runtime values.

Method Summary

All Methods Instance Methods Abstract Methods Deprecated Methods
Modifier and Type	Method	Description
`@Nullable Value`	`adaptType(@Nullable Type type)`	Deprecated. use `adaptType(CelType)` instead.
`@Nullable Value`	`adaptType(CelType type)`	Adapt the check-time `type` instance to a runtime `Value`.
`@Nullable Value`	`resolveObjectType(java.lang.Object obj, @Nullable Value checkedTypeValue)`	Resolve the CEL type of the `obj`, using the `checkedTypeValue` as hint for type disambiguation.

- Method Detail
  - resolveObjectType
```
@Nullable Value resolveObjectType(java.lang.Object obj,
                                  @Nullable Value checkedTypeValue)
```
    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.
  - adaptType
```
@Nullable Value adaptType(CelType type)
```
    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.
  - adaptType
```
@Deprecated
@Nullable Value adaptType(@Nullable Type type)
```
    Deprecated.
    use adaptType(CelType) instead. This only exists to maintain compatibility with legacy async evaluator.
    
    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.
