MXSerializer (plexus-utils API)

java.lang.Object
- org.codehaus.plexus.util.xml.pull.MXSerializer

All Implemented Interfaces:

XmlSerializer
```
public class MXSerializer
extends java.lang.Object
implements XmlSerializer
```
Implementation of XmlSerializer interface from XmlPull V1 API. This implementation is optimized for performance and low memory footprint.
Implemented features:
- FEATURE_NAMES_INTERNED - when enabled all returned names (namespaces, prefixes) will be interned and it is required that all names passed as arguments MUST be interned
- FEATURE_SERIALIZER_ATTVALUE_USE_APOSTROPHE
Implemented properties:
- PROPERTY_SERIALIZER_INDENTATION
- PROPERTY_SERIALIZER_LINE_SEPARATOR

```
    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:

    Description copied from interface: XmlSerializer
    
    Return namespace that corresponds to given prefix If there is no prefix bound to this namespace return null but if generatePrefix is false then return generated prefix.
    NOTE: if the prefix is empty string "" and default namespace is bound to this prefix then empty string ("") is returned.
    NOTE: prefixes "xml" and "xmlns" are already bound will have values as defined Namespaces in XML specification

  - 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.

  - 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 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 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 first call to startTag() or when last endTag() is called to close first startTag().
    
    Specified by:
    
    getName in interface XmlSerializer

                       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 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.

                        throws java.io.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:

                     throws java.io.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='').
