Open a TileDB Resource at Write Mode

Source: R/open_write.R
open_write.Rd

Open a URI, tiledb::tiledb_array(), tiledb::tiledb_group(), TileDBArray or TileDBGroup at write mode with an optional timestamp.

Usage

# S3 method for class 'TileDBArray'
open_write(object, timestamp = NULL, ...)

# S3 method for class 'tiledb_array'
open_write(object, timestamp = NULL, ...)

# S3 method for class 'TileDBGroup'
open_write(object, timestamp = NULL, ...)

# S3 method for class 'tiledb_group'
open_write(object, timestamp = NULL, ...)

# S3 method for class 'character'
open_write(object, timestamp = NULL, ctx = NULL, ...)

Arguments

object

An R object that contains a TileDB resource pointer.

timestamp

Optional datetime object of class "POSIXct" to write at this timestamp.

...

Other arguments passed to methods. Not used.

ctx

Optional tiledb::tiledb_ctx() object.

Value

An object of class tiledb_array or tiledb_group depending on the method; the object is opened in ‘WRITE’ mode.

Details

Opening a character string should be a valid URI path for a TileDB resource.

Objects other than a URI character are implicitly closed if found opened and re-opened at write mode.

Note that when using the timestamp argument, the TileDBArray, TileDBGroup and their subclasses will have different timestamps from the returning TileDB object. This is by design, you can not write at timestamp using TileDBArray and TileDBGroup interface only via open_write() method.
