## Class StringOutputter

- java.lang.Object
- - com.icl.saxon.output.Outputter
  - - com.icl.saxon.output.StringOutputter

-     public final class StringOutputter
      extends Outputter

  This class allows output to be generated. It channels output requests to an Emitter which does the actual writing. This is a specialized and simplified version that is used to handle xsl:attribute, xsl:comment, and xsl:processing-instruction.

      Description copied from class: `Outputter`
      Synchronize the state of the Outputter with that of the underlying Emitter
      Specified by:

      Throws:
        `javax.xml.transform.TransformerException`

    - #### getOutputProperties

      Specified by:
        `getOutputProperties` in class `Outputter`

    - #### write

          public void write(java.lang.String s)
                     throws javax.xml.transform.TransformerException

      Produce literal output. This is written as is, without any escaping. The method is provided for Java applications that wish to output literal HTML text. It is not used by the XSL system, which always writes using specific methods such as writeStartTag().
      Specified by:
        `write` in class `Outputter`
      Throws:
        `javax.xml.transform.TransformerException`

    - #### writeContent

          public void writeContent(java.lang.String s)
                            throws javax.xml.transform.TransformerException

      Produce text content output.
      Special characters are escaped using XML/HTML conventions if the output format requires it.
      Specified by:
        `writeContent` in class `Outputter`
      Parameters:
        `s` - The String to be output
      Throws:
        `javax.xml.transform.TransformerException` - for any failure

    - #### writeContent

          public void writeContent(char[] chars,
                          int start,
                          int length)
                            throws javax.xml.transform.TransformerException

      Produce text content output.
      Special characters are escaped using XML/HTML conventions if the output format requires it.
      Specified by:
        `writeContent` in class `Outputter`
      Parameters:
        `chars` - Character array to be output
        `start` - start position of characters to be output
        `length` - number of characters to be output
      Throws:
        `javax.xml.transform.TransformerException` - for any failure

    - #### writeStartTag

          public void writeStartTag(int nameCode)
                             throws javax.xml.transform.TransformerException

      Output an element start tag. With this outputter, this is a recoverable error.
      Specified by:
        `writeStartTag` in class `Outputter`
      Parameters:
        `nameCode` - The element name code
      Throws:
        `javax.xml.transform.TransformerException`

    - #### checkAttributePrefix

          public int checkAttributePrefix(int nameCode)
                                   throws javax.xml.transform.TransformerException

      Check that the prefix for an attribute is acceptable, returning a substitute prefix if not. The prefix is acceptable unless a namespace declaration has been written that assignes this prefix to a different namespace URI. This method also checks that the attribute namespace has been declared, and declares it if not.
      Specified by:
        `checkAttributePrefix` in class `Outputter`
      Throws:
        `javax.xml.transform.TransformerException`

    - #### writeNamespaceDeclaration

          public void writeNamespaceDeclaration(int nscode)
                                         throws javax.xml.transform.TransformerException

      Output a namespace declaration.
      This is added to a list of pending namespaces for the current start tag. If there is already another declaration of the same prefix, this one is ignored. Note that unlike SAX2 startPrefixMapping(), this call is made AFTER writing the start tag.
      Specified by:
        `writeNamespaceDeclaration` in class `Outputter`
      Parameters:
        `nscode` - The namespace code
      Throws:
        `javax.xml.transform.TransformerException` - if there is no start tag to write to (created using writeStartTag), or if character content has been written since the start tag was written.

    - #### copyNamespaceNode

          public void copyNamespaceNode(int nscode)
                                 throws javax.xml.transform.TransformerException

      Copy a namespace node to the current element node (Rules defined in XSLT 1.0 errata)
      Specified by:
        `copyNamespaceNode` in class `Outputter`
      Throws:
        `javax.xml.transform.TransformerException`

    - #### thereIsAnOpenStartTag

          public boolean thereIsAnOpenStartTag()

      Test whether there is an open start tag. This determines whether it is possible to write an attribute node at this point.
      Specified by:
        `thereIsAnOpenStartTag` in class `Outputter`

    - #### writeAttribute

          public void writeAttribute(int nameCode,

                            boolean noEscape)
                              throws javax.xml.transform.TransformerException

      Output an attribute value.
      No-op in this implementation.

        `writeAttribute` in class `Outputter`
      Parameters:
        `name` - The name of the attribute
        `value` - The value of the attribute
        `noEscape` - True if it's known there are no special characters in the value. If unsure, set this to false.
      Throws:
        `javax.xml.transform.TransformerException` - if there is no start tag to write to (created using writeStartTag), or if character content has been written since the start tag was written.

    - #### writeEndTag
