Method Details

applyCardinality

public boolean applyCardinality(String inputKey,
 Object input,
 WalkedPath walkedPath,
 Object parentContainer)

If this CardinalitySpec matches the inputkey, then do the work of modifying the data and return true.

Specified by:

applyCardinality in class CardinalitySpec

Returns:

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

applyToParentContainer

public Object applyToParentContainer(String inputKey,
 Object input,
 WalkedPath walkedPath,
 Object parentContainer)

This should only be used by composite specs with an '@' child

Returns:

null if no work was done, otherwise returns the re-parented data

performCardinalityAdjustment

private Object performCardinalityAdjustment(String inputKey,
 Object input,
 WalkedPath walkedPath,
 Map parentContainer,
 MatchedElement thisLevel)

Returns:

null if no work was done, otherwise returns the re-parented data

getMatch

private MatchedElement getMatch(String inputKey,
 WalkedPath walkedPath)
