Field Detail

yamlClassConstructors

protected final Map<NodeId,Construct> yamlClassConstructors

It maps the node kind to the the Construct implementation. When the runtime class is known then the implicit tag is ignored.

yamlConstructors

protected final Map<Tag,Construct> yamlConstructors

It maps the (explicit or implicit) tag to the Construct implementation. It is used:
1) explicit tag - if present.
2) implicit tag - when the runtime class of the instance is unknown (the node has the Object.class)

yamlMultiConstructors

protected final Map<String,Construct> yamlMultiConstructors

It maps the (explicit or implicit) tag to the Construct implementation. It is used when no exact match found.

rootTag

protected Tag rootTag

Constructor Detail

BaseConstructor

public BaseConstructor()

Method Detail

setComposer

public void setComposer(Composer composer)

checkData

public boolean checkData()

Check if more documents available

Returns:

true when there are more YAML documents in the stream

getData

public Object getData()

Construct and return the next document

Returns:

constructed instance

getSingleData

public Object getSingleData(Class<?> type)

Ensure that the stream contains a single document and construct it

Returns:

constructed instance

Throws:

ComposerException - in case there are more documents in the stream

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

getConstructor

protected Construct getConstructor(Node node)

Get the constructor to construct the Node. For implicit tags if the runtime class is known a dedicated Construct implementation is used. Otherwise the constructor is chosen by the tag.

Parameters:

node - Node to be constructed

Returns:

Construct implementation for the specified node

constructScalar

protected Object constructScalar(ScalarNode node)

createDefaultList

protected List<Object> createDefaultList(int initSize)

createDefaultSet

protected Set<Object> createDefaultSet(int initSize)

createArray

protected <T> T[] createArray(Class<T> type,
                              int size)

constructSequence

protected List<? extends Object> constructSequence(SequenceNode node)

constructSet

                                      Collection<Object> collection)

constructArrayStep2

protected Object constructArrayStep2(SequenceNode node,
