Interface UsesIntermediateObject<CONTEXT>

Type Parameters:

CONTEXT - as Context type. See ContextAware, getInterMediateResults()

All Superinterfaces:

ContextAware<CONTEXT>, Serializable

All Known Implementing Classes:

Method Summary

Modifier and Type	Method and Description
CONTEXT	getInterMediateResults()
Collection<String>	getResultNamesThatAreOptional() By default matching using getResultNamesUsed() is strict.
Collection<String>	getResultNamesUsed() name(s) of the result variable used (optional & mandatory)
void	setIntermediateResults(CONTEXT intermediateResults) The value(s) to set for this Before the Operation is performed.
void	setResultNamesThatAreOptional(Collection<String> resultsThatAreOptional) By default matching using getResultNamesUsed() is strict.

Method Detail

getResultNamesUsed

Collection<String> getResultNamesUsed()

name(s) of the result variable used (optional & mandatory)

Returns:

Collection of String

setIntermediateResults

void setIntermediateResults(CONTEXT intermediateResults)

The value(s) to set for this Before the Operation is performed.

Parameters:

intermediateResults - - Map of keyName and Value

getResultNamesThatAreOptional

Collection<String> getResultNamesThatAreOptional()

By default matching using getResultNamesUsed() is strict. i.e. if a result required is not obtained from the context it should/would result in a RuntimeException.

By specifying the result is optional in this list in ADDITION to getResultNamesUsed() will mute and continue since the instance of AbstractEntityTransformer is aware that it is optional. TODO: Add Unit test case for this scenario

Returns:

Collection of String

setResultNamesThatAreOptional

void setResultNamesThatAreOptional(Collection<String> resultsThatAreOptional)

By default matching using getResultNamesUsed() is strict. i.e. if a result required is not obtained from the context it should/would result in a RuntimeException.

By specifying the result is optional in this list in ADDITION to getResultNamesUsed() will mute and continue since the instance of AbstractEntityTransformer is aware that it is optional.
