Interface CanonicalValueSupport<T extends CanonicalValue<T>>

Type Parameters:

T - canonical value type

All Superinterfaces:

CanonicalValueValidator<T,T>

All Known Implementing Classes:

AbstractCanonicalValueSupport, Decimal64.Support, Uint16.Support, Uint32.Support, Uint64.Support, Uint8.Support

 @ThreadSafe
public interface CanonicalValueSupport<T extends CanonicalValue<T>>
extends CanonicalValueValidator<T,T>

Support for a CanonicalValue subclasses. An implementation of this interface must be registered in the system and be available from each CanonicalValue object.

Note: never implement this interface directly, subclass AbstractCanonicalValueSupport instead.

This interface allows a CanonicalValue to be instantiated from a String. The implementation is expected to perform all checks implied by the corresponding YANG data model.

Method Detail

fromString

Variant<T,CanonicalValueViolation> fromString(String str)

Create a instance for a string representation. Implementations of this method are required to perform checks equivalent to the YANG data model restrictions attached to the corresponding YANG type. Non-canonical format strings must be accepted and result in objects equal to objects obtained from the corresponding canonical format.

Parameters:

str - String representation

Returns:

A CanonicalValue instance or CanonicalValueViolation if str does not conform

Throws:

NullPointerException - if str is null

fromCanonicalString

default Variant<T,CanonicalValueViolation> fromCanonicalString(String str)

Create a instance for the canonical string representation. Implementations of this method may perform optimizations based on the assumption the string is canonical, but should still report errors when a mismatch is detected.

Parameters:

str - String representation

Returns:

A CanonicalValue instance or CanonicalValueViolation if str does not conform

Throws:

NullPointerException - if str is null

unsafe

default <X extends CanonicalValue<X>> CanonicalValueSupport<X> unsafe()

Unsafe cast to a factory type.

Returns:

This instance cast to specified type
