Method Details

getLiteralChildren

public Map<String, ShiftrSpec> getLiteralChildren()

Specified by:

getLiteralChildren in interface OrderedCompositeSpec

getComputedChildren

public List<ShiftrSpec> getComputedChildren()

Specified by:

getComputedChildren in interface OrderedCompositeSpec

determineExecutionStrategy

public ExecutionStrategy determineExecutionStrategy()

Specified by:

apply

public boolean apply(String inputKey,
 Optional<Object> inputOptional,
 WalkedPath walkedPath,
 Map<String,Object> output,
 Map<String,Object> context)

If this Spec matches the inputKey, then perform one step in the Shiftr parallel treewalk. Step one level down the input "tree" by carefully handling the List/Map nature the input to get the "one level down" data. Step one level down the Spec tree by carefully and efficiently applying our children to the "one level down" data.

Specified by:

apply in interface BaseSpec

Returns:

true if this this spec "handles" the inputKey such that no sibling specs need to see it
