DynamicTableSource.Context (Flink : 2.0-SNAPSHOT API)

All Known Subinterfaces:

LookupTableSource.LookupContext, ScanTableSource.ScanContext

All Known Implementing Classes:

LookupRuntimeProviderContext, ScanRuntimeProviderContext

Enclosing interface:

DynamicTableSource
```
@PublicEvolving
public static interface DynamicTableSource.Context
```
Base context for creating runtime implementation via a ScanTableSource.ScanRuntimeProvider and LookupTableSource.LookupRuntimeProvider.
It offers utilities by the planner for creating runtime implementation with minimal dependencies to internal data structures.
Methods should be called in ScanTableSource.getScanRuntimeProvider(ScanTableSource.ScanContext) and LookupTableSource.getLookupRuntimeProvider(LookupTableSource.LookupContext). The returned instances are Serializable and can be directly passed into the runtime implementation class.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`DynamicTableSource.DataStructureConverter`	`createDataStructureConverter(DataType producedDataType)`	Creates a converter for mapping between objects specified by the given `DataType` and Flink's internal data structures that can be passed into a runtime implementation.
`<T> TypeInformation<T>`	`createTypeInformation(DataType producedDataType)`	Creates type information describing the internal data structures of the given `DataType`.
`<T> TypeInformation<T>`	`createTypeInformation(LogicalType producedLogicalType)`	Creates type information describing the internal data structures of the given `LogicalType`.

- Method Detail
  - createTypeInformation
```
<T> TypeInformation<T> createTypeInformation(DataType producedDataType)
```
    Creates type information describing the internal data structures of the given DataType.

    ResolvedSchema.toPhysicalRowDataType()
  - createTypeInformation
```
<T> TypeInformation<T> createTypeInformation(LogicalType producedLogicalType)
```
    Creates type information describing the internal data structures of the given LogicalType.
  - createDataStructureConverter
```
DynamicTableSource.DataStructureConverter createDataStructureConverter(DataType producedDataType)
```
    Creates a converter for mapping between objects specified by the given DataType and Flink's internal data structures that can be passed into a runtime implementation.
    For example, a Row and its fields can be converted into RowData, or a (possibly nested) POJO can be converted into the internal representation for structured types.
