with_attributes

The with_attributes method returns a table that is identical to the source table, but with the specified attributes added.

note

The table attributes are immutable once defined, and are mostly used internally by the Deephaven engine. For advanced users, certain predefined plug-in attributes provide a way to extend Deephaven with custom-built plug-ins.

Syntax​

with_attributes(attrs: Dict[str, Any]) -> Table

Parameters​

ParameterTypeDescription
attrs>Dict[str, Any]

A Dict of table attribute names and their values.

Returns​

A table with the specified attributes added.

Examples​

In this example, we create a source table, then create a result table with a call to with_attributes(). This returns a result table that is identical to our source table, but with the attribute we specify ("MyAttribute") added.

from deephaven import new_table
from deephaven.column import double_col, string_col

source = new_table(
    [
        double_col("Doubles", [3.1, 5.45, -1.0]),
        string_col("Strings", ["Creating", "New", "Tables"]),
    ]
)

attr_dict = {"MyAttribute": "MyBooleanValue"}

result = source.with_attributes(attr_dict)

print(source.attributes())
print(result.attributes())
