----------------------------------
Summary: [Python] [Gandiva] Expose ToString and result type
information
Key: ARROW-11342
URL: https://issues.apache.org/jira/browse/ARROW-11342
Project: Apache Arrow
Issue Type: Improvement
Reporter: Will Jones
Assignee: Will Jones
To make it easier to build and introspect the expression trees, I would like to
expose the ToString() methods on Node, Expression, and Condition, as well as
the methods exposing the fields and types inside.
{code:python}
import pyarrow as pa
import pyarrow.gandiva as gandiva
builder = gandiva.TreeExprBuilder()
print(builder.make_literal(1000.0, pa.float64()))
<pyarrow.gandiva.Node object at 0x7f36fd37ecf0>
{code}
