Builds a list of Transformers.

Parameters:

names - - a list of transformers separated by commands

muleContext - the current muleContext. This is used to look up transformers in the registry

Returns:

a list (possibly empty) of transformers or

Throws:

DefaultMuleException - if any of the transformers cannot be found

Checks whether a given value is a valid output for a transformer.

Parameters:

transformer - the transformer used to validate

value - the output value

Throws:

TransformerException - if the out[ut value is of a unexpected type.
