Method Detail

create

public static RowDataProjection create(Schema schema,
                                       Schema projectedSchema)

Creates a projecting wrapper for RowData rows.

This projection will not project the nested children types of repeated types like lists and maps.

Parameters:

schema - schema of rows wrapped by this projection

projectedSchema - result schema of the projected rows

Returns:

a wrapper to project rows

create

public static RowDataProjection create(org.apache.flink.table.types.logical.RowType rowType,
                                       Types.StructType schema,
                                       Types.StructType projectedSchema)

Creates a projecting wrapper for RowData rows.

This projection will not project the nested children types of repeated types like lists and maps.

Parameters:

rowType - flink row type of rows wrapped by this projection

schema - schema of rows wrapped by this projection

projectedSchema - result schema of the projected rows

Returns:

a wrapper to project rows
