Class StructNodeFactory

  • public final class StructNodeFactory
extends java.lang.Object
    Helper factory class for creating correct node objects. It is not used by main code and exists only for tests and to simplify manual tree modifications in custom UpdateListener implementations.

    In contrast to comments parser model, structural model (snakeyaml's) use exact parsed values and ignores all comments.

                                        int lineNum,
                                        java.lang.String key,
                                        java.lang.String value)
        Could be used to create any node type: with both key and value it would be property, without value - subtree root and without both key and value - stub for virtualized list item.
        Parameters:
        root - root node (may be null)
        padding - padding
        lineNum - target line number
        key - property name (may be null)
        value - property value (may be null for subtree root)
        Returns:
        created node

      • createListObject

        public static StructNode createListObject​(StructNode root,
                                          int padding,

                                         java.lang.String value)
        Creates scalar list value.
        Parameters:
        root - root node (may be null)
        padding - padding
        lineNum - target dash line number
        value - property value lines (may be null)
        Returns:
