## Class EditorKit

- java.lang.Object
- - javax.swing.text.EditorKit

- All Implemented Interfaces:
    Serializable, Cloneable
  Direct Known Subclasses:
    DefaultEditorKit

      public abstract class EditorKit
      extends Object
      implements Cloneable, Serializable

  Establishes the set of things needed by a text component to be a reasonably functioning editor for some type of text content. The EditorKit acts as a factory for some kind of policy. For example, an implementation of html and rtf can be provided that is replaceable with other implementations.

  A kit can safely store editing state as an instance of the kit will be dedicated to a text component. New kits will normally be created by cloning a prototype kit. The kit will have it's `setComponent` method called to establish it's relationship with a JTextComponent.

    - #### EditorKit

          public EditorKit()

      Construct an EditorKit.

  - ### Method Detail

    - #### deinstall

          public void deinstall(JEditorPane c)

        `c` - the JEditorPane

    - #### getContentType

          public abstract String getContentType()

      Gets the MIME type of the data that this kit represents support for.

        the type

    - #### getViewFactory

          public abstract ViewFactory getViewFactory()

      Fetches a factory that is suitable for producing views of any models that are produced by this kit.

        the factory

          public abstract Action[] getActions()

      Fetches the set of commands that can be used on a text component that is using a model and view produced by this kit.
      Returns:
        the set of actions

    - #### createCaret

          public abstract Caret createCaret()

      Fetches a caret that can navigate through views produced by the associated ViewFactory.
      Returns:
        the caret

    - #### createDefaultDocument

          public abstract Document createDefaultDocument()

      Creates an uninitialized text storage model that is appropriate for this type of editor.
      Returns:
        the model

    - #### read

          public abstract void read(InputStream in,
                                    Document doc,
                                    int pos)
                             throws IOException,
                                    BadLocationException

      Inserts content from the given stream which is expected to be in a format appropriate for this kind of content handler.
      Parameters:
        `in` - The stream to read from
        `doc` - The destination for the insertion.
        `pos` - The location in the document to place the content >= 0.
      Throws:
        `IOException` - on any I/O error
        `BadLocationException` - if pos represents an invalid location within the document.

    - #### write

          public abstract void write(OutputStream out,
                                     Document doc,
                                     int pos,
                                     int len)
                              throws IOException,
                                     BadLocationException

      Writes content from a document to the given stream in a format appropriate for this kind of content handler.
      Parameters:
        `out` - The stream to write to
        `doc` - The source for the write.
        `pos` - The location in the document to fetch the content from >= 0.
        `len` - The amount to write out >= 0.
      Throws:
        `IOException` - on any I/O error
        `BadLocationException` - if pos represents an invalid location within the document.

    - #### read

          public abstract void read(Reader in,
                                    Document doc,
                                    int pos)
                             throws IOException,
                                    BadLocationException

      Inserts content from the given stream which is expected to be in a format appropriate for this kind of content handler.

      Since actual text editing is unicode based, this would generally be the preferred way to read in the data. Some types of content are stored in an 8-bit form however, and will favor the InputStream.

      Parameters:
        `in` - The stream to read from
        `doc` - The destination for the insertion.
        `pos` - The location in the document to place the content >= 0.
      Throws:
        `IOException` - on any I/O error
        `BadLocationException` - if pos represents an invalid location within the document.

    - #### write

          public abstract void write(Writer out,
                                     Document doc,
                                     int pos,
                                     int len)
                              throws IOException,
                                     BadLocationException

      Writes content from a document to the given stream in a format appropriate for this kind of content handler.

      Since actual text editing is unicode based, this would generally be the preferred way to write the data. Some types of content are stored in an 8-bit form however, and will favor the OutputStream.

      Parameters:
        `out` - The stream to write to
        `doc` - The source for the write.
        `pos` - The location in the document to fetch the content >= 0.
        `len` - The amount to write out >= 0.
      Throws:
        `IOException` - on any I/O error
        `BadLocationException` - if pos represents an invalid location within the document.
