Overview ¶

Package datatype provides interfaces for arbitrary datatypes supported in DVID. Each datatype implements the interface and handles conversion of its data into the key-value pairs or other base storage elements. Each data type provides a domain-specific HTTP API and possibly command-line actions.

Data types are declared in the main dvid.go file under imports. An example:

import (

// Declare the data types this DVID executable will support
_ "github.com/janelia-flyem/dvid/datatype/imageblk"
_ "github.com/janelia-flyem/dvid/datatype/labelblk"
_ "randomsite.org/datatypes/myfoo"

)

Philosophy note: Rather than creating base packages that handle all sorts of similar data (e.g., uint8, uint16, rgab8, float32, n-dimensional float32), DVID code tries to be as simple as possible even if it means copying and replacing types. This will lend itself to using Go generate versus generics-style of programming. For now, though, it will simplify the code of each package.
