Method Detail

isWrapperType

public static boolean isWrapperType(java.lang.String typeName)

Checks if the fully-qualified protobuf type name is a wrapper type.

createFunctionType

@Internal
public static OpaqueType createFunctionType(CelType resultType,
                                            java.lang.Iterable<CelType> argumentTypes)

Create an abstract type with an expected result type (first argument in the parameter) and the argument types.

CEL Library Internals. Do Not Use.

format

public static java.lang.String format(CelType type)

Method to adapt a simple Type into a String representation.

This method can also format global functions. See the formatFunction(dev.cel.common.types.CelType, java.lang.Iterable<dev.cel.common.types.CelType>, boolean, boolean) methods for richer control over function formatting.

formatFunction

public static java.lang.String formatFunction(CelType resultType,
                                              java.lang.Iterable<CelType> argTypes,
                                              boolean isInstance,
                                              boolean typeParamToDyn)

Format a function signature string from the input argTypes and resultType.

When isInstance is true, the argTypes[0] type is used as the receiver type.

When resultType is null, the function signature omits the result type. This is useful for computing overload signatures.

When typeParamToDyn is true, parameterized type argument are represented as Types.DYN values.

isWellKnownType

public static boolean isWellKnownType(java.lang.String typeName)

getWellKnownCelType

public static java.util.Optional<CelType> getWellKnownCelType(java.lang.String typeName)
