tiledb_vfs_read: Read from a TileDB VFS Filehandle

In tiledb: Universal Storage Engine for Sparse and Dense Multidimensional Arrays

Read from a TileDB VFS Filehandle

Description

This interface currently defaults to reading an integer vector. This is suitable for R objects as a raw vector used for (de)serialization can be mapped easily to an integer vector. It is also possible to memcpy to the contiguous memory of an integer vector should other (non-R) data be transferred.

Usage

tiledb_vfs_read(fh, offset, nbytes, ctx = tiledb_get_context())

Arguments

fh	A TileDB VFS Filehandle external pointer as returned from tiledb_vfs_open
offset	A scalar integer64 value with the byte offset from the beginning of the file with a of zero.
nbytes	A scalar integer64 value with the number of bytes to be read.
ctx	(optional) A TileDB Ctx object

Value

The binary file content is returned as an integer vector.
