Method Detail

kind

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

isAssignableFrom

public boolean isAssignableFrom(CelType other)

Description copied from class: CelType

Determine whether this type is assignable from the other type value.

Defaults to an equality test.

Overrides:

isAssignableFrom in class CelType

targetType

public abstract CelType targetType()

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

withFreshTypeParamVariables

public CelType withFreshTypeParamVariables(java.util.function.Function<java.lang.String,java.lang.String> varNameGenerator)

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:

withFreshTypeParamVariables in class CelType

create

public static NullableType create(CelType targetType)
