Class BaseMarkupSerializer

java.lang.Object
org.apache.xml.serialize.BaseMarkupSerializer
All Implemented Interfaces:
DOMSerializer, Serializer, ContentHandler, DocumentHandler, DTDHandler, DeclHandler, LexicalHandler

public abstract class BaseMarkupSerializer extends Object implements ContentHandler, DocumentHandler, LexicalHandler, DTDHandler, DeclHandler, DOMSerializer, Serializer
Deprecated.
This class was deprecated in Xerces 2.9.0. It is recommended that new applications use the DOM Level 3 LSSerializer or JAXP's Transformation API for XML (TrAX) for serializing XML. See the Xerces documentation for more information.
Base class for a serializer supporting both DOM and SAX pretty serializing of XML/HTML/XHTML documents. Derives classes perform the method-specific serializing, this class provides the common serializing mechanisms.

The serializer must be initialized with the proper writer and output format before it can be used by calling setOutputCharStream(java.io.Writer) or setOutputByteStream(java.io.OutputStream) for the writer and setOutputFormat(org.apache.xml.serialize.OutputFormat) for the output format.

The serializer can be reused any number of times, but cannot be used concurrently by two threads.

If an output stream is used, the encoding is taken from the output format (defaults to UTF-8). If a writer is used, make sure the writer uses the same encoding (if applies) as specified in the output format.

The serializer supports both DOM and SAX. DOM serializing is done by calling serialize(Document) and SAX serializing is done by firing SAX events and using the serializer as a document handler. This also applies to derived class.

If an I/O exception occurs while serializing, the serializer will not throw an exception directly, but only throw it at the end of serializing (either DOM or SAX's DocumentHandler.endDocument().

For elements that are not specified as whitespace preserving, the serializer will potentially break long text lines at space boundaries, indent lines, and serialize elements on separate lines. Line terminators will be regarded as spaces, and spaces at beginning of line will be stripped.

When indenting, the serializer is capable of detecting seemingly element content, and serializing these elements indented on separate lines. An element is serialized indented when it is the first or last child of an element, or immediate following or preceding another element.

      Throws:
      IOException - An I/O exception occured while serializing

      Throws:
      IOException - An I/O exception occurred while serializing
    • characters

      protected void characters(String text) throws IOException
      Deprecated.
      Called to print the text contents in the prevailing element format. Since this method is capable of printing text as CDATA, it is used for that purpose as well. White space handling is determined by the current element state. In addition, the output format can dictate whether the text is printed as CDATA or unescaped.
      Parameters:
      text - The text to print
      Throws:
      IOException - An I/O exception occured while serializing
    • getEntityRef

      Character entity name, or null
    • serializeElement

      protected abstract void serializeElement(Element elem) throws IOException

      Parameters:
      elem - The element to serialize
      Throws:
      IOException - An I/O exception occured while serializing
    • serializePreRoot

      protected void serializePreRoot() throws IOException
      Deprecated.
      Comments and PIs cannot be serialized before the root element, because the root element serializes the document type, which generally comes first. Instead such PIs and comments are accumulated inside a vector and serialized by calling this method. Will be called when the root element is serialized and when the document finished serializing.
      Throws:
      IOException - An I/O exception occured while serializing

    • printText

      protected void printText(char[] chars, int start, int length, boolean preserveSpace, boolean unescaped) throws IOException
      Deprecated.
      Called to print additional text with whitespace handling. If spaces are preserved, the text is printed as if by calling printText(String,boolean,boolean) with a call to Printer.breakLine() for each new line. If spaces are not preserved, the text is broken at space boundaries if longer than the line width; Multiple spaces are printed as such, but spaces at beginning of line are removed.
      Parameters:
      chars - The text to print
      start - The start offset
      length - The number of characters
      preserveSpace - Space preserving flag
      unescaped - Print unescaped

      protected void printDoctypeURL(String url) throws IOException
      Deprecated.
      Print a document type public or system identifier URL. Encapsulates the URL in double quotes, escapes non-printing characters and print it equivalent to printText(char[], int, int, boolean, boolean).
      Parameters:
      url - The document type url to print
      Throws:
      IOException
    • printEscaped

      IOException
