…ypes ### What changes were proposed in this pull request? this PR is a follow up of #46685. ### Why are the changes needed? `StructType.treeString` uses `DataType.typeName` to generate the tree string, however, the `typeName` in python is a class method and can not return the same string for parameterized types. ``` In [2]: schema = StructType().add("c", CharType(10), True).add("v", VarcharType(10), True).add("d", DecimalType(10, 2), True).add("ym00", YearM ...: onthIntervalType(0, 0)).add("ym01", YearMonthIntervalType(0, 1)).add("ym11", YearMonthIntervalType(1, 1)) In [3]: print(schema.treeString()) root |-- c: char (nullable = true) |-- v: varchar (nullable = true) |-- d: decimal (nullable = true) |-- ym00: yearmonthinterval (nullable = true) |-- ym01: yearmonthinterval (nullable = true) |-- ym11: yearmonthinterval (nullable = true) ``` it should be ``` In [4]: print(schema.treeString()) root |-- c: char(10) (nullable = true) |-- v: varchar(10) (nullable = true) |-- d: decimal(10,2) (nullable = true) |-- ym00: interval year (nullable = true) |-- ym01: interval year to month (nullable = true) |-- ym11: interval month (nullable = true) ``` ### Does this PR introduce _any_ user-facing change? no, this feature was just added and not release out yet. ### How was this patch tested? added tests ### Was this patch authored or co-authored using generative AI tooling? no Closes #46711 from zhengruifeng/tree_string_fix.
