- ## Method Details

  - ### addConnectorTo

    Connector addConnectorTo(Node target)
    adds a new Connector to the given target node and returns the new connector for optional further editing (style); also enlists the Connector on the target Node object.

  - ### addConnectorTo

    Connector addConnectorTo(String targetNodeId)
    as above, using String targetNodeId instead of Node object to establish the connector.

  - ### createChild

    Node createChild()
    inserts *new* node as child, takes care of all construction work and internal stuff inserts as last child.

  - ### createChild

    Node createChild(Object value)
    like `createChild()` but sets the node text to the given text.

         // instead of
         def child = node.createChild(); child.setObject(value);
         // use
         def child = node.createChild(value);

    Since:
      1.2

  - ### createChild

    Node createChild(int position)
    inserts *new* node as child, takes care of all construction work and internal stuff

  - ### appendChild

    Node appendChild(NodeRO node)
    inserts a copy of node as a new child.
    Since:
      1.2

  - ### appendBranch

    Node appendBranch(NodeRO node)
    inserts a copy of the branch starting with node as a new child branch.
    Since:
      1.2

  - ### appendAsCloneWithSubtree

    Node appendAsCloneWithSubtree(NodeRO toBeCloned)
    inserts the node as a clone of toBeCloned including its current and/or future subtree. That is all changes of descendent nodes of toBeCloned are reflected in the subtree of the new node and vice versa.
    Note: Cloning works symmetrically so we could better speak of two shared nodes instead of clone and cloned since none of both is privileged.
    Returns:
      the new child node
    Throws:
      `IllegalArgumentException` - if a) this node (the to-be-parent) is contained in the subtree of toBeCloned, b) toBeCloned is the root node, c) toBeCloned comes from a different map.
    Since:
      1.5

  - ### appendAsCloneWithoutSubtree

    Note: Cloning works symmetrically so we could better speak of two shared nodes instead of clone and cloned since none of both is privileged.
    Returns:
      the new child node
    Throws:
      `IllegalArgumentException` - if a) this node (the to-be-parent) is contained in the subtree of toBeCloned, b) toBeCloned is the root node, c) toBeCloned comes from a different map.
    Since:
      1.5

  - ### pasteAsClone

    void pasteAsClone()
    inserts the node(s) copied from clipboard as clone(s). Errors like if the clipboard doesn't contain proper content will only be reported to the log. You should prefer `appendAsCloneWithSubtree(Proxy.NodeRO)` or `appendAsCloneWithoutSubtree(Proxy.NodeRO)` instead if possible - they give you more control.

    - This methods provides automatic conversion to String in a way that node.getNote().getXyz() methods will be able to convert the string properly to the wanted type.
    - Special conversion is provided for dates and calendars: They will be converted in a way that node.note.date and node.note.calendar will work. All other types are converted via value.toString().
    - If the conversion result is not valid HTML it will be automatically converted to HTML.

           // converts numbers and other stuff with toString()
           node.note = 1.2
           assert node.note.text == "<html><body><p>1.2"
           assert node.note.plain == "1.2"
           assert node.note.num == 1.2d
           // == dates
           // a date in some non-UTC time zone
           def date = new java.text.SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSSZ").
               parse("1970-01-01 00:00:00.000-0200")
           // converts to "1970-01-01T02:00:00.000+0000" (GMT)
           // - note the shift due to the different time zone
           // - the missing end tags don't matter for rendering
           node.note = date
           assert node.note == "<html><body><p>1970-01-01T02:00:00.000+0000"

    Since:
      1.9.0

  - ### setText

         node.text = '006'
         assert node.object.class.simpleName == "String"
         node.object = '006'
         assert node.text == '6'
         assert node.object.class.simpleName == "Long"

    Since:
      1.2, semantics changed for Strings with 1.2.17
    See Also:
      - `setObject(Object)`

  - ### setObject

    void setObject(Object value)
    A node's text object is normally String valued but it can be of any type since every Object can be converted to String for display. This methods provides automatic conversion to String in a way that node.to.getXyz() methods will be able to convert the string properly to the wanted type.

    Special support is provided for numbers, dates and calendars that are stored unconverted. For display of them a standard formatter is used (use #setFormat() to change it). You may also pass `IFormattedObject` instances (`FormattedDate`, `FormattedNumber` or `FormattedObject`) directly to determine the format in one pass.

    All other types are converted via value.toString().

    Numbers

         double number = 1.2222222d
         node.object = number
         // to enable math with node.object its type is not FormattedNumber
         assert node.object.class.simpleName == "Double"
         assert node.to.object.class.simpleName == "Double"
         // use globally bound TextUtils object
         def defaultNumberFormat = textUtils.defaultNumberFormat
         assert node.format != null
         // e.g. "1.22"
         assert node.text == defaultNumberFormat.format(number)
         assert node.to.num == number
         assert node.to.num + 1.0 == number + 1.0
         assert node.object + 1.0 == number + 1.0

    Dates

         def date = new Date(0) // when Unix time began
         node.object = date
         assert node.object.class.simpleName == "FormattedDate"
         assert node.to.object.class.simpleName == "FormattedDate"
         // use globally bound TextUtils object
         def defaultDateFormat = textUtils.defaultDateFormat
         assert node.object.toString() == defaultDateFormat.format(date)
         assert node.format == defaultDateFormat.pattern
         // e.g. "01/01/1970"
         assert node.text == defaultDateFormat.format(date)
         assert node.to.date == date

    Date/Time

         def date = new Date(0) // when Unix time began
         // the default format for dates does not contain a time component. Use node.dateTime to override it.
         node.dateTime = date
         assert node.object.class.simpleName == "FormattedDate"
         assert node.to.object.class.simpleName == "FormattedDate"
         // use globally bound TextUtils object
         def defaultDateFormat = textUtils.defaultDateTimeFormat
         assert node.object.toString() == defaultDateFormat.format(date)
         assert node.format == defaultDateFormat.pattern
         // e.g. "01/01/1970 01:00"
         assert node.text == defaultDateFormat.format(date)
         assert node.to.date == date

    Parameters:

    Since:
      1.2

  - ### setDateTime

    void setDateTime(Date date)

  - ### setFormat

    void setFormat(String format)
    sets the format string of the formatter. It has to be appropriate for the data type of the contained object, otherwise the format is simply ignored. For instance use "dd.MM.yyyy" for dates but not for numbers:

         node.object = new Date()
         node.format = "dd.MMM.yyyy"  // ok: "13.07.2011"
         node.format = "#.00"  // still "13.07.2011". See log: "cannot format 13.07.2011 with #.00: multiple points"

    Numbers:

         node.object = 1.122
         node.format = "#.##"   // ok: "1.12" (US, GB, ...) or "1,12" (Germany, ...)
         node.format = "#.0000" // ok: "1.1220" (US, GB, ...) or "1,1220" (Germany, ...)

           assert node.attributes.size() == 1
           assert node.attributes.getFirst("one attrib") == "1.22" // note the type conversion
