tiledbsoma.PointCloudDataFrame.exists

classmethod PointCloudDataFrame.exists(uri: str, context: SOMATileDBContext | None = None, tiledb_timestamp: int | datetime | None = None) → bool

Finds whether an object of this type exists at the given URI.

Parameters:

  • uri – The URI to open.

  • context – If provided, the SOMATileDBContext to use when creating and attempting to access this object.

  • tiledb_timestamp – The TileDB timestamp to open this object at, measured in milliseconds since the Unix epoch. When unset (the default), the current time is used.

Raises:

TypeError – If the uri is not a string.

Examples

>>> with tiledbsoma.open("a_dataframe") as soma_df:
...     print(soma_df.soma_type)
...
SOMADataFrame
>>> tiledbsoma.DataFrame.exists("./a_dataframe")
True
>>> tiledbsoma.SparseNDArray.exists("./a_dataframe")
False
