Key

public Key(String rawJsonKey,
 Object spec)

Method Details

parseSpec

public static Set<Key> parseSpec(Map<String,Object> spec)

Factory-ish method that recursively processes a Mapinvalid input: '<'String, Object> into a Set objects.

Parameters:

spec - Simple Jackson default Mapinvalid input: '<'String,Object> input

Returns:

Set of Keys from this level in the spec

processSpec

private static Set<Key> processSpec(boolean parentIsArray,
 Map<String,Object> spec)

Recursively walk the spec input tree. Handle arrays by telling DefaultrKeys if they need to be ArrayKeys, and to find the max default array length.

applyChildren

public void applyChildren(Object defaultee)

This is the main "recursive" method. The defaultee should never be null, because the defaultee wasn't null, it was null and we created it, OR there was a mismatch between the Defaultr Spec and the input, and we didn't recurse.

getLiteralIntKey

protected abstract int getLiteralIntKey()

applyChild

protected abstract void applyChild(Object container)

Apply this Key to the defaultee. If this Key is a WildCard key, this may apply to many entries in the container.

getOrCount

public int getOrCount()

isArrayOutput

public boolean isArrayOutput()

getOp

public OPS getOp()

getOutputArraySize

public int getOutputArraySize()

createOutputContainerObject

public Object createOutputContainerObject()
