Hi
Yes there is only one implementation but it is used as a dependency and
configured to be resolved by name. The reader is configured in code
Component.For<ICsvReader>()
.ImplementedBy<CommaSeparetedCsvReader>()
.DependsOn(new { SkipHeader = true, HeaderRowsToSkip = 2 } )
.Named("CommaSeparetedCsvReader_Skips2Rows")
.Lifestyle.Transient
Component.For<ICsvReader>()
.ImplementedBy<CommaSeparetedCsvReader>()
.DependsOn(new { SkipHeader = true, HeaderRowsToSkip = 1 } )
.Named("CommaSeparetedCsvReader_Skips1Row")
.Lifestyle.Transient
Component.For<ICsvReader>()
.ImplementedBy<CommaSeparetedCsvReader>()
.Named("CommaSeparetedCsvReader")
.Lifestyle.Transient
These are used as dependency in a processor class. It is configured in XML,
so that in can be manipulated at runtime
<component id="Processor
type="Processor">
<parameters>
<reader>CommaSeparetedCsvReader_Skips2Rows</reader>
</parameters>
</component>
Ideally I would like to register only the CommaSeparetedCsvReader component
but when an attempt is made to resolve CommaSeparetedCsvReader_Skips2Rows
it should strip the suffix, parse it and change the properties accordingly.
Is it possible to somehow modify the Resolve() behavior?
Thanks
Tom
