               throws java.io.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 other than startTag() or setPrefix() is called next, an exception will be thrown.

NOTE: prefixes "xml" and "xmlns" are already bound and cannot 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:

java.io.IOException

Description copied from interface: XmlSerializer

Returns prefix that corresponds to the given namespace. If there is no prefix bound to this namespace returns null, but if generatePrefix is false, then returns generated prefix.

NOTE: if the prefix is the empty string "" and the default namespace is bound to this prefix, then the empty string ("") is returned.

NOTE: prefixes "xml" and "xmlns" are already bound, and will have values as defined Namespaces in XML specification

Specified by:

getPrefix in interface XmlSerializer

getPrefix

protected java.lang.String getPrefix(java.lang.String namespace,
                                     boolean generatePrefix,

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 is observed.

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

Specified by:

getDepth in interface XmlSerializer

getNamespace

public java.lang.String getNamespace()

Description copied from interface: XmlSerializer

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

NOTE: that notably means 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 java.lang.String getName()

Description copied from interface: XmlSerializer

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

Specified by:

getName in interface XmlSerializer

Returns:

namespace set by startTag() that is currently in scope

startTag

public XmlSerializer startTag(java.lang.String namespace,
                              java.lang.String name)
                       throws java.io.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, only the name is. If namespace is the empty string, then the serializer will make sure that the default empty namespace is declared (in XML 1.0 xmlns='') or will throw IllegalStateException if the default namespace is already bound to the non-empty string.

Specified by:

startTag in interface XmlSerializer

Throws:

java.io.IOException

attribute

public XmlSerializer attribute(java.lang.String namespace,
                               java.lang.String name,
                               java.lang.String value)
                        throws java.io.IOException

Description copied from interface: XmlSerializer

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

Specified by:

attribute in interface XmlSerializer

Throws:

java.io.IOException

closeStartTag

protected void closeStartTag()
                      throws java.io.IOException

Throws:

java.io.IOException

endTag

public XmlSerializer endTag(java.lang.String namespace,
                            java.lang.String name)
                     throws java.io.IOException

Description copied from interface: XmlSerializer

Writes end tag. Namespace and name are repeated simply in order to 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, only the name is. If namespace is empty string then the serialzier will make sure that the default empty namespace is declared (in XML 1.0 xmlns='').

Specified by:

endTag in interface XmlSerializer

Throws:

java.io.IOException
