fromString
public java.nio.ByteBuffer fromString(java.lang.String source) throws MarshalException
Description copied from class:AbstractType
get a byte representation of the given string.- Specified by:
fromString
in classAbstractType<Duration>
- Throws:
MarshalException
-
isValueCompatibleWithInternal
public boolean isValueCompatibleWithInternal(AbstractType<?> otherType)
Description copied from class:AbstractType
Needed to handle ReversedType in value-compatibility checks. Subclasses should implement this instead of isValueCompatibleWith().- Overrides:
isValueCompatibleWithInternal
in classAbstractType<Duration>
-
