Type Members

1. class FileIdDao[T] extends IdDao[String, T]

   

2. 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:

   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

3. case class FileTimestampDao[T](rootDir: Path)(implicit saveValue: Persist[T], fromBytes: FromBytes[T], idFor: HasId[T]) extends TimestampDao[T] with Product with Serializable

   

   Writes stuff (T values) down under the given directory structures:

   Writes stuff (T values) down under the given directory structures:

   <dir>/dates/<date>/<hour>/<minute>/<second>_<nano>_<id> = *data*

   where *data* is determined by the given Persist, which is either the data itself or a linked file.

   The implicit Persist may only link to the former instead of serializing the data

   T

   the value to save/retrieve

   rootDir

   the directory under which all the data will be stored

   saveValue

   the Persist instance to use in saving (or linking) the data.

   fromBytes

   a means of deserializing a T from bytes

   idFor

   the ability to name the T values w/ an ID (as multiple Ts can exist for the same instant)
