Method Detail

of

public static TestBoundedTable of(java.lang.Object... args)

Convenient way to build a mocked bounded table.

e.g.

 TestUnboundedTable
   .of(Types.BIGINT, "order_id",
       Types.INTEGER, "site_id",
       Types.DOUBLE, "price",
       Types.TIMESTAMP, "order_time")
 

of

public static TestBoundedTable of(Schema type)

Build a mocked bounded table with the specified type.

addRows

public TestBoundedTable addRows(java.lang.Object... args)

Add rows to the builder.

Sample usage:

 addRows(
   1, 3, "james", -- first row
   2, 5, "bond"   -- second row
   ...
 )
