fixedSize

public int fixedSize()

Description copied from interface: FixedWidthType

The fixed amount of memory a value object instance of type t requires. (t is the type described by our DataType interface or something that implements FixedWidthType) Implementations here may not be 100% accurate because sizes may vary between JVM implementations and then there is also stuff like padding and other JVM magic.

Specified by:

fixedSize in interface FixedWidthType
