case class FileTagDao[T](rootDir: Path, maxTagLen: Int, maxTagValueLen: Int)(implicit persist: Persist[T], hasId: HasId[T], fromBytes: FromBytes[T]) extends TagDao[T] with Product with Serializable

Stores things in the format:

When a tag value is not alphanumeric, or is longer than 'maxTagValueLen':

<root dir>/tags/<tag>/<value hash>/<id>/.value = <value> <root dir>/tags/<tag>/<value hash>/<id>/.data = <data>

or, when the tag value IS alphanumber and within 'maxTagValueLen':

<root dir>/tags/<tag>/<value>/<id>/.data

It also stores:

<root dir>/ids/<id>/<tag> = <value>

for queries on just the id (e.g. list tags), or when the id and tag are known

T

the value type

rootDir

the directory to store the data

maxTagLen

the maximum allowed length of tags

persist

the ability to persist T values

hasId

the ability to determine an ID for T values

fromBytes

the ability to read T values from byte arrays
