Constructor Detail

XMLWriterBase

public XMLWriterBase(java.lang.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")

XMLWriterBase

public XMLWriterBase(XMLWriterBase base,
                     java.lang.String[] uris)
Copy constructor. This initializes the extension namespace information from an existing instance.

Parameters:
base - existing instance
uris - ordered array of URIs for namespaces used in document
Method Detail

writeXMLDecl

public 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

public void startTagOpen(int index,
                         java.lang.String name)
                  throws java.io.IOException
Generate open start tag. This allows attributes 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

public 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

public void addAttribute(int index,
                         java.lang.String name,
                         java.lang.String value)
                  throws java.io.IOException
Add attribute to current open start tag. This is only valid after a call to startTagOpen(int, java.lang.String) or startTagNamespaces(int, java.lang.String, int[], java.lang.String[]) and before the corresponding call to closeStartTag().

Parameters:
index - namespace URI index number
name - unqualified attribute name
value - text value for attribute
Throws:
java.io.IOException - on error writing to document

closeStartTag

public void closeStartTag()
                   throws java.io.IOException
Close the current open start tag. This is only valid after a call to startTagOpen(int, java.lang.String).

Throws:
java.io.IOException - on error writing to document

closeEmptyTag

public void closeEmptyTag()
                   throws java.io.IOException
Close the current open start tag as an empty element. This is only valid after a call to startTagOpen(int, java.lang.String).

Throws:
java.io.IOException - on error writing to document

startTagClosed

public void startTagClosed(int index,
                           java.lang.String name)
                    throws java.io.IOException
Generate closed start tag. No attributes or namespaces can be added to a start tag written using this call.

Parameters:
index - namespace URI index number
name - unqualified element name
Throws:
java.io.IOException - on error writing to document

endTag

public void endTag(int index,
                   java.lang.String name)
            throws java.io.IOException
Generate end tag.

Parameters:
index - namespace URI index number
name - unqualified element name
Throws:
java.io.IOException - on error writing to document

writeComment

public void writeComment(java.lang.String text)
                  throws java.io.IOException
Write comment to document.

Parameters:
text - comment text
Throws:
java.io.IOException - on error writing to document

writeEntityRef

public void writeEntityRef(java.lang.String name)
                    throws java.io.IOException
Write entity reference to document.

Parameters:
name - entity name
Throws:
java.io.IOException - on error writing to document

writeDocType

public void writeDocType(java.lang.String name,
                         java.lang.String sys,
                         java.lang.String pub,
                         java.lang.String subset)
                  throws java.io.IOException

Parameters:
name - root element name
sys - system ID (null if none, must be non-null for public ID to be used)
pub - public ID (null if none)
subset - internal subset (null if none)

Write processing instruction to document.

Parameters:
target - processing instruction target name
data - processing instruction data
Throws:
java.io.IOException - on error writing to document

flush

public abstract void flush()
                    throws java.io.IOException
Flush document output. Forces out all output generated to this point.

close

public abstract void close()
                    throws java.io.IOException
Close document output. Completes writing of document output, including closing the output medium.

Throws:
java.io.IOException - on error writing to document

reset

public 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. It is automatically called when output is set.

Specified by:
reset in interface IXMLWriter
Overrides:
reset in class XMLWriterNamespaceBase

createChildWriter

public abstract IXMLWriter createChildWriter(java.lang.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 XMLWriterBase(String[]))
Returns:
child writer
