YamlSlurper (Groovy 6.0.0-RC-2)

groovy.yaml.YamlSlurper

```
public class YamlSlurper
extends Object
```
Represents a YAML parser
YAML anchors and aliases are not resolved: an alias is returned as a plain string holding the anchor's name, and a merge key (<<) is left as a literal entry. This comes from the Jackson YAML backend and is a deliberate limitation there. The Processing YAML user guide covers it, along with what to use when a document relies on anchors.
Since:
3.0.0

  - <T> public T parseAs(Class<T> type, Reader reader)
    
    Parse YAML from a reader into a typed object.
    Parameters:

    Type Parameters:
    T - the target type
    Returns:
    a typed object
    Since:
    6.0.0
  - <T> public T parseAs(Class<T> type, InputStream stream)
    
    Parse YAML from an input stream into a typed object.
    Parameters:
    type - the target type
    stream - the input stream of YAML
    Type Parameters:
    T - the target type
    Returns:
    a typed object
    Since:
    6.0.0
  - <T> public T parseAs(Class<T> type, File file)
    
    Parse YAML from a file into a typed object.
    Parameters:
    type - the target type
    file - the YAML file
    Type Parameters:
    T - the target type
    Returns:
    a typed object
    Since:
    6.0.0
  - <T> public T parseAs(Class<T> type, Path path)
    
    Parse YAML from a path into a typed object.
    Parameters:
    type - the target type
    path - the path to the YAML file
    Type Parameters:
    T - the target type
    Returns:
    a typed object
    Since:
    6.0.0
  - public Object parseText(String yaml)
    
    Parse the content of the specified yaml into a tree of Nodes.
    Parameters:
    yaml - the content of yaml
    Returns:
    the root node of the parsed tree of Nodes
  - <T> public T parseTextAs(Class<T> type, String yaml)
    
    Parse the content of the specified YAML text into a typed object using Jackson databinding. Supports @JsonProperty and @JsonFormat annotations for property mapping and type conversion.
    Parameters:
    type - the target type
    yaml - the content of YAML
    Type Parameters:
    T - the target type
    Returns:
    a typed object
    Since:
    6.0.0
  - public YamlSlurper setDateHandling(JsonDateHandling dateHandling)
    
    Chooses what a string in full ISO-8601 or JSON-date form becomes, matching the date handling JsonSlurper offers. The default is JsonDateHandling.STRING: a date-like string is left as a String, which is what this slurper has always produced. A date carrying no time, such as "2026-09-04", is left as a String whatever is chosen here.
    Choosing anything other than JsonDateHandling.STRING switches the underlying parser to JsonParserType.INDEX_OVERLAY so the conversion takes effect; as a consequence, the iteration order of a map with more than a handful of entries is no longer the document order. Pass null or JsonDateHandling.STRING to restore the default parser and string handling.
    Parameters:
    dateHandling - what a date-like string should become
    Returns:
    this slurper, for chaining
