protected org.yaml.snakeyaml.Yaml |
createYaml()
Create the
Yaml instance to use. |
protected Map<String,Object> |
getFlattenedMap(Map<String,Object> source)
Return a flattened version of the given map, recursively following any nested Map
or Collection values.
|
protected void |
process(YamlProcessor.MatchCallback callback)
Provide an opportunity for subclasses to process the Yaml parsed from the supplied
resources.
|
void |
setDocumentMatchers(YamlProcessor.DocumentMatcher... matchers)
A map of document matchers allowing callers to selectively use only
some of the documents in a YAML resource.
|
void |
setMatchDefault(boolean matchDefault)
Flag indicating that a document for which all the
document matchers abstain will
nevertheless match. |
void |
setResolutionMethod(YamlProcessor.ResolutionMethod resolutionMethod)
Method to use for resolving resources.
|
void |
setResources(Resource... resources)
Set locations of YAML
resources to be loaded. |
public void setDocumentMatchers(YamlProcessor.DocumentMatcher... matchers)
--- lines, and each document is converted
to properties before the match is made. E.g.
environment: dev
url: http://dev.bar.com
name: Developer Setup
---
environment: prod
url:http://foo.bar.com
name: My Cool App
when mapped with
documentMatchers = YamlProcessor.mapMatcher({"environment": "prod"})
would end up as
environment=prod
url=http://foo.bar.com
name=My Cool App
url=http://dev.bar.com
