- DESCRIPTION:
Retrieves all values (only) present in a teradataml GeoDataFrame.
Values are retrieved as per a numpy.ndarray representation of a teradataml GeoDataFrame.
This format is equivalent to the get_values() representation of a Pandas GeoDataFrame.

num_rows:
Optional Argument.
Specifies the number of rows to retrieve values for from a teradataml GeoDataFrame.
The num_rows parameter specified needs to be an integer value.
Default Value: 99999
Types: int
RETURNS:
Numpy.ndarray representation of a teradataml GeoDataFrame
RAISES:
TeradataMlException
EXAMPLES:
>>> load_example_data("geodataframe","sample_streets")
>>> df1 = GeoDataFrame.from_table('sample_streets')
>>> df1
street_name street_shape
skey
1 Coast Blvd LINESTRING (12 12,18 17)
1 Main Street LINESTRING (2 2,3 2,4 1)
>>>
# Retrieve all values from the teradataml GeoDataFrame
>>> vals = df1.get_values()
>>> vals
array([['Main Street', 'LINESTRING (2 2,3 2,4 1)'],
['Coast Blvd', 'LINESTRING (12 12,18 17)']], dtype=object)
>>>
# Retrieve values for a given number of rows from the teradataml GeoDataFrame
>>> vals = df1.get_values(num_rows = 1)
>>> vals
array([['Coast Blvd', 'LINESTRING (12 12,18 17)']], dtype=object)
