- ## Method Details

  - ### getNodeMetaData

    default <T> T getNodeMetaData(Object key)
    Gets the node metadata.
    Parameters:
      `key` - the metadata key
    Returns:
      the node metadata value for this key

  - ### getNodeMetaData

    default <T> T getNodeMetaData(Object key, Function<?,? extends T> valFn)
    Gets the node metadata.
    Parameters:
      `key` - the metadata key
      `valFn` - the metadata value supplier
    Returns:
      the node metadata value for this key

  - ### copyNodeMetaData

    default void copyNodeMetaData(NodeMetaDataHandler other)
    Copies all node metadata from the other node to this one
    Parameters:
      `other` - the other node

  - ### setNodeMetaData

    default void setNodeMetaData(Object key, Object value)
    Sets the node metadata.
    Parameters:
      `key` - the metadata key
      `value` - the metadata value
    Throws:
      `GroovyBugError` - if key is null or there is already metadata for key

  - ### putNodeMetaData

    default Object putNodeMetaData(Object key, Object value)
    Sets the node metadata but allows overwriting values.
    Parameters:
      `key` - the metadata key

    Returns:
      the old node metadata value for this key
    Throws:
      `GroovyBugError` - if key is null

  - ### removeNodeMetaData

    default void removeNodeMetaData(Object key)
    Removes a node metadata entry.
    Parameters:
      `key` - the metadata key
    Throws:
      `GroovyBugError` - if the key is null

  - ### getNodeMetaData

    default Map<?,?> getNodeMetaData()
    Returns an unmodifiable view of the current node metadata.
    Returns:
      the node metadata. Always not null.

  - ### getMetaDataMap
