org.htmlparser
Class StringNodeFactory

java.lang.Object
  org.htmlparser.PrototypicalNodeFactory
      org.htmlparser.StringNodeFactory

All Implemented Interfaces:

NodeFactory, java.io.Serializable

Deprecated. Use PrototypicalNodeFactory#setTextPrototype(Text)

A more efficient implementation of affecting all string nodes, is to replace the Text node prototype in the PrototypicalNodeFactory with a custom TextNode that performs the required operation.

For example, if you were using:

 StringNodeFactory factory = new StringNodeFactory();
 factory.setDecode(true);
 

to decode all text issued from Text.toPlainTextString(), you would instead create a subclass of TextNode and set it as the prototype for text node generation:

 PrototypicalNodeFactory factory = new PrototypicalNodeFactory ();
 factory.setTextPrototype (new TextNode () {
     public String toPlainTextString()
     {
         return (org.htmlparser.util.Translate.decode (super.toPlainTextString ()));
     }
 });
 

Similar constructs apply to removing escapes and converting non-breaking spaces, which were the examples previously provided.

Using a subclass avoids the wrapping and delegation inherent in the decorator pattern, with subsequent improvements in processing speed and memory usage.

Field Detail

mDecode

protected boolean mDecode

Deprecated.

Flag to toggle decoding of strings. Decoding occurs via the method, org.htmlparser.util.Translate.decode()

mRemoveEscapes

protected boolean mRemoveEscapes

Deprecated.

Flag to toggle removal of escape characters, like \n and \t. Escape character removal occurs via the method, org.htmlparser.util.ParserUtils.removeEscapeCharacters()

mConvertNonBreakingSpaces

protected boolean mConvertNonBreakingSpaces

Deprecated.

Flag to toggle converting non breaking spaces (from to space " "). If true, this will happen inside StringNode's toPlainTextString.
