Abstract Annotation Group

This is an abstract class to augment the base TiledbGroup class with fields necessary for the child Annotation- classes. Currently it only adds the dimension_name field.

Super classes

tiledbsc::TileDBObject -> tiledbsc::TileDBGroup -> AnnotationGroup

Public fields

dimension_name

Optional name of the dimension shared by all arrays within the group (typically obs_id or var_id).

Method new()

Create a new TileDBGroup-based Annotation class.

Usage

AnnotationGroup$new(
  uri,
  dimension_name = NULL,
  verbose = TRUE,
  config = NULL,
  ctx = NULL
)

Arguments

uri

URI for the TileDB group.

dimension_name

Optional name of the dimension shared by all of the group's member arrays.

verbose

Print status messages

config

optional configuration

ctx

optional tiledb context

---

Method set_query()

Set dimension values to slice from the array members.

Usage

AnnotationGroup$set_query(dims = NULL, attr_filter = NULL)

Arguments

dims

a named list of character vectors. Each must correspond to a dimension shared by all array members.

attr_filter

a TileDB query condition for attribute filtering pushdown.

---

Method reset_query()

Reset the group member queries.

Usage

AnnotationGroup$reset_query(dims = TRUE, attr_filter = TRUE)

Arguments

dims

Clear the defined dimension ranges?

attr_filter

Clear the defined attribute filters?

Returns

NULL

---

Method clone()

The objects of this class are cloneable with this method.

Usage

AnnotationGroup$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
