Class SMOutputContext

java.lang.Object
  org.codehaus.staxmate.out.SMOutputContext

public final class SMOutputContext
extends java.lang.Object

Class that encapsulates details about context in which StaxMate output is done. The most important of the details is the stream writer to use (since that is eventually invoked to do the real output), and its properties.

Usually the process of outputting XML content with StaxMate starts by instantiating an SMOutputContext. It can then be used to create output fragments; all of which bind to that context. Context is thus what "connects" various fragments when they are buffered (when there may or may not be child/parent relationships yet defined).

Context is also used (in addition to storing output relevant settings and acting as a fragment factory) as the owner of various other objects, most notable namespaces. All local namespaces are owned by one and only one context.

Method Detail

setIndentation

public void setIndentation(java.lang.String indentStr,
                           int startOffset,
                           int step)

This method can be called to enable or disable heuristic indentation for the output done using this output context.

Here are some example calls:

context.setIndentation("\n ", 1, 2); // indent by lf and 2 spaces per level context.setIndentation(null, 0, 0); // disable indentation context.setIndentation("\r\n\t\t\t\t\t\t\t\t", 2, 1); // indent by windows lf and 1 tab per level

Parameters:

indentStr - String to use for indentation; if non-null, will enable indentation, if null, will disable it. Used in conjunction with the other arguments

startOffset - Initial character offset for the first level of indentation (current context; usually root context): basically, number of leading characters from indentStr to output.

step - Number of characters to add from the indentation String for each new level (and to subtract when closing levels).

createInstance

                                      throws javax.xml.stream.XMLStreamException

Throws:

createInstance

                                      throws javax.xml.stream.XMLStreamException

Throws:

javax.xml.stream.XMLStreamException

createDocument

public SMOutputDocument createDocument()
                                throws javax.xml.stream.XMLStreamException

Method used to create a StaxMate output fragment that corresponds to a single well-formed XML document. Assumption, then, is that the underlying stream writer has only been created, but no writes have yet been done.

This version of the method calls the matching no-arguments method in the stream writer.

Throws:

javax.xml.stream.XMLStreamException

createDocument

public SMOutputDocument createDocument(java.lang.String version,
                                       java.lang.String encoding)
                                throws javax.xml.stream.XMLStreamException

Method used to create a StaxMate output fragment that corresponds to a single well-formed XML document. Assumption, then, is that the underlying stream writer has only been created, but no writes have yet been done.

This version of the method calls the matching stream writer method which takes full xml declaration information.

Throws:

javax.xml.stream.XMLStreamException

createDocument

public SMOutputDocument createDocument(java.lang.String version,
                                       java.lang.String encoding,

Throws:

createRootFragment

public SMRootFragment createRootFragment()
                                  throws javax.xml.stream.XMLStreamException

Method to use when outputting an XML sub-tree, in which case the underlying stream writer may be (or has been) used for outputting XML content in addition to content that is output using StaxMate. Resulting fragment is not buffered, and will thus be fully streamed (except for buffering caused by adding buffered children)

Throws:

javax.xml.stream.XMLStreamException

createBufferedFragment
