Method Detail

value

public abstract Message value()

Description copied from class: CelValue

The underlying value. This is typically the Java native value or a derived instance of CelValue (ex: an element in lists or key/value pair in maps).

Specified by:

value in class CelValue

celType

public abstract CelType celType()

Description copied from class: CelValue

The CelType that represents this value.

Specified by:

celType in class CelValue

isZeroValue

public boolean isZeroValue()

Description copied from class: CelValue

Returns true if the CelValue.value() is a zero value for its type.

Specified by:

isZeroValue in class CelValue

select

public CelValue select(StringValue field)

Description copied from interface: SelectableValue

Performs field selection. The behavior depends on the concrete implementation of the value being selected. For structs and maps, this must throw an exception if the field does not exist. For optional values, this will return an optional.none().

find

public java.util.Optional<CelValue> find(StringValue field)

Description copied from interface: SelectableValue

Finds the field. This will return an Optional.empty() if the field does not exist. This can be used for presence testing.

create

public static ProtoMessageValue create(Message value,
                                       CelDescriptorPool celDescriptorPool,
                                       ProtoCelValueConverter protoCelValueConverter)
