Parameters:

name - The name of feature to be retrieved.

Returns:

The value of named feature.

setFeature

public void setFeature(String name,
                       boolean value)

Description copied from interface: XmlSerializer

Set feature identified by name (recommended to be URI for uniqueness). Some well known optional features are defined in http://www.xmlpull.org/v1/doc/features.html. If feature is not recognized or can not be set then IllegalStateException MUST be thrown.

Specified by:

setFeature in interface XmlSerializer

setProperty

public void setProperty(String name,
                        Object value)

Description copied from interface: XmlSerializer

Set the value of a property. (the property name is recommended to be URI for uniqueness). Some well known optional properties are defined in http://www.xmlpull.org/v1/doc/properties.html. If property is not recognized or can not be set then IllegalStateException MUST be thrown.

Specified by:

setProperty in interface XmlSerializer

setPrefix

public void setPrefix(String prefix,
                      String namespace)
               throws IOException

Description copied from interface: XmlSerializer

Binds the given prefix to the given namespace. This call is valid for the next element including child elements. The prefix and namespace MUST be always declared even if prefix is not used in element (startTag() or attribute()) - for XML 1.0 it must result in declaring xmlns:prefix='namespace' (or xmlns:prefix="namespace" depending what character is used to quote attribute value).

NOTE: this method MUST be called directly before startTag() and if anything but startTag() or setPrefix() is called next there will be exception.

NOTE: prefixes "xml" and "xmlns" are already bound and can not be redefined see: Namespaces in XML Errata.

NOTE: to set default namespace use as prefix empty string.

Specified by:

setPrefix in interface XmlSerializer

Parameters:

prefix - must be not null (or IllegalArgumentException is thrown)

namespace - must be not null

Throws:

IOException

setOutput

public void setOutput(Writer writer)

Description copied from interface: XmlSerializer

Set the output to the given writer.

WARNING no information about encoding is available!

Specified by:

setOutput in interface XmlSerializer

setOutput

public void setOutput(OutputStream os,
                      String encoding)
               throws IOException

Description copied from interface: XmlSerializer

Set to use binary output stream with given encoding.

Specified by:

setOutput in interface XmlSerializer

Throws:

IOException

startDocument

public void startDocument(String encoding,
                          Boolean standalone)
                   throws IOException

Description copied from interface: XmlSerializer

Write <?xml declaration with encoding (if encoding not null) and standalone flag (if standalone not null) This method can only be called just after setOutput.

Specified by:

startDocument in interface XmlSerializer

Throws:

IOException

startTag

public XmlSerializer startTag(String namespace,
                              String name)
                       throws IOException

Description copied from interface: XmlSerializer

Writes a start tag with the given namespace and name. If there is no prefix defined for the given namespace, a prefix will be defined automatically. The explicit prefixes for namespaces can be established by calling setPrefix() immediately before this method. If namespace is null no namespace prefix is printed but just name. If namespace is empty string then serializer will make sure that default empty namespace is declared (in XML 1.0 xmlns='') or throw IllegalStateException if default namespace is already bound to non-empty string.

Specified by:

startTag in interface XmlSerializer

Throws:

IOException

attribute

public XmlSerializer attribute(String namespace,
                               String name,
                               String value)
                        throws IOException

Description copied from interface: XmlSerializer

Write an attribute. Calls to attribute() MUST follow a call to startTag() immediately. If there is no prefix defined for the given namespace, a prefix will be defined automatically. If namespace is null or empty string no namespace prefix is printed but just name.

Specified by:

attribute in interface XmlSerializer

Throws:

IOException

flush

public void flush()
           throws IOException

Description copied from interface: XmlSerializer

Write all pending output to the stream. If method startTag() or attribute() was called then start tag is closed (final >) before flush() is called on underlying output stream.

NOTE: if there is need to close start tag (so no more attribute() calls are allowed) but without flushing output call method text() with empty string (text("")).

Specified by:

flush in interface XmlSerializer

Throws:

IOException

endTag

public XmlSerializer endTag(String namespace,
                            String name)
                     throws IOException

Description copied from interface: XmlSerializer

Write end tag. Repetition of namespace and name is just for avoiding errors.

Background: in kXML endTag had no arguments, and non matching tags were very difficult to find... If namespace is null no namespace prefix is printed but just name. If namespace is empty string then serializer will make sure that default empty namespace is declared (in XML 1.0 xmlns='').

Specified by:

endTag in interface XmlSerializer

Throws:

IOException

getNamespace

public String getNamespace()

Description copied from interface: XmlSerializer

Returns the namespace URI of the current element as set by startTag().

NOTE: that means in particular that:

• if there was startTag("", ...) then getNamespace() returns ""
• if there was startTag(null, ...) then getNamespace() returns null

Specified by:

getNamespace in interface XmlSerializer

Returns:

namespace set by startTag() that is currently in scope

getName

public String getName()

Description copied from interface: XmlSerializer

Returns the name of the current element as set by startTag(). It can only be null before first call to startTag() or when last endTag() is called to close first startTag().

Specified by:

getName in interface XmlSerializer

Returns:

namespace set by startTag() that is currently in scope

getDepth

public int getDepth()

Description copied from interface: XmlSerializer

Returns the current depth of the element. Outside the root element, the depth is 0. The depth is incremented by 1 when startTag() is called. The depth is decremented after the call to endTag() event was observed.

 <!-- outside -->     0
 <root>               1
   sometext                 1
     <foobar>         2
     </foobar>        2
 </root>              1
 <!-- outside -->     0
 

Specified by:
