Method Details

allowsEmpty

public boolean allowsEmpty()

Description copied from class: AbstractType

Defines if the type allows an empty set of bytes (new byte[0]) as valid input. The AbstractType.validate(Object, ValueAccessor) and AbstractType.compose(Object, ValueAccessor) methods must allow empty bytes when this returns true, and must reject empty bytes when this is false.

As of this writing, the main user of this API is for testing to know what types allow empty values and what types don't, so that the data that gets generated understands when ByteBufferUtil.EMPTY_BYTE_BUFFER is allowed as valid data.

Overrides:

allowsEmpty in class AbstractType<String>

concat

public ByteBuffer concat(String left,
 String right)
