    • Method Detail

      • init

        void init()
           throws java.io.IOException
        Initialize writer.
        Throws:
        java.io.IOException
      • getNestingDepth

        int getNestingDepth()
        Get the current element nesting depth. Elements are only counted in the depth returned when they're officially open - after the start tag has been output and before the end tag has been output.
        Returns:
        number of nested elements at current point in output
      • getNamespaceCount

        int getNamespaceCount()
        Get the number of namespaces currently defined. This is equivalent to the index of the next extension namespace added.
        Returns:
        namespace count
      • setIndentSpaces

        void setIndentSpaces​(int count,
                             java.lang.String newline,
                             char indent)
        Set nesting indentation. This is advisory only, and implementations of this interface are free to ignore it. The intent is to indicate that the generated output should use indenting to illustrate element nesting.
        Parameters:
        count - number of character to indent per level, or disable indentation if negative (zero means new line only)
        newline - sequence of characters used for a line ending (null means use the single character '\n')
        indent - whitespace character used for indentation
      • writeXMLDecl

        void writeXMLDecl​(java.lang.String version,
                          java.lang.String encoding,
                          java.lang.String standalone)
                   throws java.io.IOException
        Write XML declaration to document. This can only be called before any other methods in the interface are called.
        Parameters:
        version - XML version text
        encoding - text for encoding attribute (unspecified if null)
        standalone - text for standalone attribute (unspecified if null)
        Throws:
        java.io.IOException - on error writing to document
      • startTagOpen

        void startTagOpen​(int index,
                          java.lang.String name)
                   throws java.io.IOException
        Generate open start tag. This allows attributes and/or namespace declarations to be added to the start tag, but must be followed by a closeStartTag() call.
        Parameters:
        index - namespace URI index number
        name - unqualified element name
        Throws:
        java.io.IOException - on error writing to document
      • startTagNamespaces

        void startTagNamespaces​(int index,
                                java.lang.String name,
                                int[] nums,
                                java.lang.String[] prefs)
                         throws java.io.IOException
        Generate start tag for element with namespaces. This creates the actual start tag, along with any necessary namespace declarations. Previously active namespace declarations are not duplicated. The tag is left incomplete, allowing other attributes to be added.
        Parameters:
        index - namespace URI index number
        name - element name
        nums - array of namespace indexes defined by this element (must be constant, reference is kept until end of element)
        prefs - array of namespace prefixes mapped by this element (no null values, use "" for default namespace declaration)
        Throws:
        java.io.IOException - on error writing to document
      • addAttribute

        void addAttribute​(int index,

                   throws java.io.IOException
        Add attribute to current open start tag. This is only valid after a call to startTagOpen(int, java.lang.String) and before the corresponding call to closeStartTag().

        java.io.IOException - on error writing to document
      • closeEmptyTag

        void closeEmptyTag()
                    throws java.io.IOException

      • indent

        void indent()
             throws java.io.IOException
        Request output indent. The writer implementation should normally indent output as appropriate. This method can be used to request indenting of output that might otherwise not be indented. The normal effect when used with a text-oriented writer should be to output the appropriate line end sequence followed by the appropriate number of indent characters for the current nesting level.
        Throws:
        java.io.IOException - on error writing to document
      • flush

        void flush()

        Flush document output. Writes any buffered data to the output medium. This does not flush the output medium itself, only any internal buffering within the writer.
        Throws:
        java.io.IOException - on error writing to document
      • close

        void close()
            throws java.io.IOException
        Close document output. Completes writing of document output, including flushing and closing the output medium.
        Throws:
        java.io.IOException - on error writing to document
      • reset

        void reset()
        Reset to initial state for reuse. The writer is serially reusable, as long as this method is called to clear any retained state information between uses.
      • getNamespaces

        java.lang.String[] getNamespaces()
        Get namespace URIs for mapping. This gets the full ordered array of namespaces known in the binding used for this marshalling, where the index number of each namespace URI is the namespace index used to lookup the prefix when marshalling a name in that namespace. The returned array must not be modified.
        Returns:
        array of namespaces
      • getNamespaceUri

        java.lang.String getNamespaceUri​(int index)
        Get URI for namespace.
        Parameters:
        index - namespace URI index number
        Returns:
        namespace URI text, or null if the namespace index is invalid
      • getNamespacePrefix

        java.lang.String getNamespacePrefix​(int index)
        Get current prefix defined for namespace.
        Parameters:
        index - namespace URI index number
        Returns:
        current prefix text, or null if the namespace is not currently mapped
      • getPrefixIndex

        int getPrefixIndex​(java.lang.String prefix)
        Get index of namespace mapped to prefix. This can be an expensive operation with time proportional to the number of namespaces defined, so it should be used with care.
        Parameters:
        prefix - text to match (non-null, use "" for default prefix)
        Returns:
        index namespace URI index number mapped to prefix
      • pushExtensionNamespaces

        void pushExtensionNamespaces​(java.lang.String[] uris)
        Append extension namespace URIs to those in mapping.
        Parameters:
        uris - namespace URIs to extend those in mapping
      • getExtensionNamespaces

        java.lang.String[][] getExtensionNamespaces()
        Get extension namespace URIs added to those in mapping. This gets the current set of extension definitions. The returned arrays must not be modified.
        Returns:
        array of arrays of extension namespaces (null if none)
      • openNamespaces

        int[] openNamespaces​(int[] nums,
                             java.lang.String[] prefs)
                      throws java.io.IOException
        Open the specified namespaces for use. This method is normally only called internally, when namespace declarations are actually written to output. It is exposed as part of this interface to allow for special circumstances where namespaces are being written outside the usual processing. The namespaces will remain open for use until the current element is closed.
        Parameters:
        nums - array of namespace indexes defined by this element (reference kept until namespaces are closed, values may be modified by this method)
        prefs - array of namespace prefixes mapped by this element (no null values, use "" for default namespace declaration)
        Returns:
        array of indexes for namespaces not previously active (the ones actually needing to be declared, in the case of text output)
        Throws:
        java.io.IOException - on error writing to document
      • pushTranslationTable

        void pushTranslationTable​(int[] table)
        Push a translation table to be used for converting namespace index numbers passed as arguments to values used for internal lookup. This allows a layer of indirection between the client code and the namespace definitions, designed for use in supporting precompiled bindings. The translated values must match the internal tables.
        Parameters:
        table - translation table to be used (null if no change)
      • popTranslationTable

        void popTranslationTable()
        Pop a translation table used for converting namespace index numbers to values matching the internal lookup.
