Constructor Detail

GenericXMLWriter

public GenericXMLWriter(String[] uris)

Constructor.

Parameters:

uris - ordered array of URIs for namespaces used in document (must be constant; the value in position 0 must always be the empty string "", and the value in position 1 must always be the XML namespace "http://www.w3.org/XML/1998/namespace")

GenericXMLWriter

public GenericXMLWriter(GenericXMLWriter base,
                        String[] uris)

Copy constructor. This takes the writer from a supplied instance, while setting a new array of namespace URIs. It's intended for use when invoking one binding from within another binding.

Parameters:

base - instance to be used as base for writer

uris - ordered array of URIs for namespaces used in document (see GenericXMLWriter(String[]))

Method Detail

setOutput

public void setOutput(Writer outw,
                      ICharacterEscaper escaper)

Set output writer and escaper. If an output writer is currently open when this is called the existing writer is flushed and closed, with any errors ignored.

Parameters:

outw - writer for document data output

escaper - character escaper for chosen encoding

setIndentSpaces

public void setIndentSpaces(int count,
                            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

writeMarkup

protected void writeMarkup(String text)
                    throws IOException

Write markup text to output. Markup text can be written directly to the output without the need for any escaping.

Specified by:

writeMarkup in class XMLWriterBase

Parameters:

text - markup text to be written

Throws:

IOException - if error writing to document

writeMarkup

protected void writeMarkup(char chr)
                    throws IOException

Write markup character to output. Markup text can be written directly to the output without the need for any escaping.

Specified by:

writeMarkup in class XMLWriterBase

Parameters:

chr - markup character to be written

Throws:

IOException - if error writing to document

defineNamespace

protected void defineNamespace(int index,
                               String prefix)

Report that namespace has been defined.

Specified by:

defineNamespace in class XMLWriterNamespaceBase

Parameters:

index - post-translation namespace URI index number

prefix - prefix used for namespace

undefineNamespace

protected void undefineNamespace(int index)

Report that namespace has been undefined.

Specified by:

undefineNamespace in class XMLWriterNamespaceBase

Parameters:

index - post-translation namespace URI index number

writePrefix

protected void writePrefix(int index)
                    throws IOException

Write namespace prefix to output. This internal method is used to handle translation of namespace indexes to internal form, and also to throw an exception when an undeclared prefix is used.

Specified by:

writePrefix in class XMLWriterBase

Parameters:

index - namespace URI index number

Throws:

IOException - if error writing to document

writeAttributeText

protected void writeAttributeText(String text)
                           throws IOException

Write attribute text to output. This needs to write the text with any appropriate escaping.

Specified by:

writeAttributeText in class XMLWriterBase

Parameters:

text - attribute value text to be written

Throws:

IOException - if error writing to document

writeTextContent

public void writeTextContent(String text)
                      throws IOException

Write ordinary character data text content to document. This needs to write the text with any appropriate escaping.

Parameters:

text - content value text

Throws:

IOException - on error writing to document

writeCData

public void writeCData(String text)
                throws IOException

Write CDATA text to document. This needs to write the text with any appropriate escaping.

Parameters:

text - content value text

Throws:

IOException - on error writing to document

indent

public void indent(int bias)
            throws IOException

Request output indent. Output the line end sequence followed by the appropriate number of indent characters.

Specified by:

indent in class XMLWriterBase

Parameters:

bias - indent depth difference (positive or negative) from current element nesting depth

Throws:

IOException - on error writing to document

indent

public void indent()
            throws IOException

Request output indent. Output the line end sequence followed by the appropriate number of indent characters for the current nesting level.

Throws:

IOException - on error writing to document

flush

public void flush()
           throws IOException

Flush document output. Forces out all output generated to this point.

Specified by:

flush in interface IXMLWriter

Specified by:

flush in class XMLWriterBase

Throws:

IOException - on error writing to document

close

public void close()
           throws IOException

Close document output. Completes writing of document output, including closing the output medium.

Specified by:

close in interface IXMLWriter

Specified by:

close in class XMLWriterBase

Throws:

IOException - on error writing to document

createChildWriter

public IXMLWriter createChildWriter(String[] uris)

Create a child writer instance to be used for a separate binding. The child writer inherits the stream and encoding from this writer, while using the supplied namespace URIs.

Parameters:

uris - ordered array of URIs for namespaces used in document (see GenericXMLWriter(String[]))

Returns:

child writer
