Class YamlObject<T>

Object
YamlObject<T>
Direct Known Subclasses:
YamlMap, YamlSeq
public class YamlObject<T> extends Object
Base class for Yaml object wrappers.

Yaml is represented as atomic types (literals, expressions) and YamlObjects (for wrapping lists and maps). The factory method create(Object) will sort out the details. These YamlObjects are used to stage data when parsing a Yaml document.

  • Field Details

    • raw

      protected T raw
      underlying raw object

  • Constructor Details

    • YamlObject

      protected YamlObject(T raw)

  • Method Details

    • create

      public static <W> YamlObject<W> create(W raw)
      Convert raw object to Yaml wrapper.

      Other data (Literals, Expressions) are considered atomic and do not provide a YamlObject representation.
      Returns:
      Yaml object wrapper, or null if the provided raw object is null.

    • map

      public YamlMap map()
      Casts this object to a YamlMap.

    • seq

      public YamlSeq seq()
      Casts this object to a YamlSeq.

    • lookup

      public Object lookup(String path)
      Raw value access via path.

      Indended for quick value lookup during test cases.

      • raw("1"): first value in a sequence
      • raw("x"): value for "x" in a map
      • raw("rules/2/symbolizers/3"): third symbolizer in second rule
      Returns:
      raw value, or null if not available

    • raw

      public T raw()
      Returns the raw object.

    • lookupY

      public Object lookupY(String path)
      See lookup(java.lang.String). Ensures that the result is wrapped as a YamlObject if it is a map, list, or array.

    • convert

      protected <C> C convert(Object obj, Class<C> clazz)
      Converts an object to the specified class.

    • toString

      public String toString()
      Yaml representation.
      Overrides:
      toString in class Object
      Returns:
      Yaml representation
