of

@Nonnull
public static RelationalStructMetaData of(@Nonnull
 DataType.StructType type)

getTypeName

public String getTypeName()

Description copied from interface: StructMetaData

Returns the name of the struct type. The user can set the struct type name in SQL explicitly by using struct <name> (...) clause.
For example: SELECT struct Foo (a, b) from T will give the struct (a, b) the name foo.

Specified by:

getTypeName in interface StructMetaData

Returns:

The name of the struct type.
