Description copied from interface: SourceRateExpression

Changes the name for this expression

Specified by:

as in interface SourceRateExpression<R>

Specified by:

as in interface SourceRateReadWriteExpression<R,W>

Parameters:

name - new name

Returns:

this

Specified by:

fillWriteRecipe in interface WriteExpression<W>

Parameters:

director - the director for the reader

builder - the recipe to fill
