Method Detail

constructSingleDocument

public Object constructSingleDocument(Optional<Node> optionalNode)

Ensure that the stream contains a single document and construct it

Parameters:

optionalNode - - composed Node

Returns:

constructed instance

construct

protected Object construct(Node node)

Construct complete YAML document. Call the second step in case of recursive structures. At the end cleans all the state.

Parameters:

node - root Node

Returns:

Java instance

constructObject

protected Object constructObject(Node node)

Construct object from the specified Node. Return existing instance if the node is already constructed.

Parameters:

node - Node to be constructed

Returns:

Java instance

constructObjectNoCheck

protected Object constructObjectNoCheck(Node node)

findConstructorFor

protected Optional<ConstructNode> findConstructorFor(Node node)

Select ConstructNode inside the provided Node or the one associated with the Tag

Parameters:

node - Node to construct an instance from

Returns:

ConstructNode implementation for the specified node

constructScalar

protected String constructScalar(ScalarNode node)

createDefaultList

protected List<Object> createDefaultList(int initSize)

createDefaultSet

protected Set<Object> createDefaultSet(int initSize)

createDefaultMap
