An opaque type's properties may only be accessed via function calls associated with the type.

Apart from protobuf messages, opaque types are the preferred extension mechanism for introducing first-order types into CEL.

public abstract CelKind kind()

Description copied from class: CelType

Return the type CelKind.

Specified by:

kind in class CelType

name

public abstract java.lang.String name()

Description copied from class: CelType

Return the type name.

For struct types this should be the fully qualified name. Be wary of introducing unqualified type names as they may collide with future CEL type.

Specified by:

name in class CelType

parameters

public abstract com.google.common.collect.ImmutableList<CelType> parameters()

Description copied from class: CelType

Return the type parameters. e.g. a map's key and value CelType.

Overrides:

parameters in class CelType

withParameters

public CelType withParameters(com.google.common.collect.ImmutableList<CelType> parameters)

Description copied from class: CelType

Instantiate a new copy of this type with alternative parameters.

If the CelType does not have any parameters, then the return value defaults to the original type instance.

Overrides:

withParameters in class CelType

public static OpaqueType create(java.lang.String typeName,
                                CelType... parameters)
