Method Details

build

@ScriptApi
public static Table build(Table sourceTable)

Use to start the construction of a Table Supplier.

Parameters:

sourceTable - the source table

Returns:

a Proxy that will supply a table

complete

@ScriptApi
public static Table complete(Table maybeSupplier)

Sets a Table Supplier to be complete. This means that the supplier will generate a table the next time a filter operation is called. This method has no affect on Tables that are not suppliers.

Parameters:

maybeSupplier - a Table that may be a supplier

Returns:

a completed Supplier or unaltered Table

getAppliedEmptyTable

@ScriptApi
public static Table getAppliedEmptyTable(Table maybeSupplier)

Gets an empty version of the supplied table with all current operations applied to it. If the Table is not a Table Supplier then this will return the table unaltered.

Parameters:

maybeSupplier - a Table that may be a supplier

Returns:

an applied empty table or an unaltered table

invoke

public Object invoke(Object proxy,
 Method method,
 Object[] args)
              throws Throwable

Specified by:

invoke in interface InvocationHandler

Throws:

Throwable
