Class MXParserCachingStrings

java.lang.Object

org.xmlpull.mxp1.MXParser

org.xmlpull.mxp1.MXParserCachingStrings

All Implemented Interfaces:

Cloneable, XmlPullParser

Direct Known Subclasses:

MXParserNonValidating

public class MXParserCachingStrings
extends MXParser
implements Cloneable

Extend MXP parser to use string cache of char[] to interned String

NOTE: it is not non-validaint parser as there is no supporting internal DTD parsing no full XML 1.0 (or 1.1) character classes are supported.

protected void	initStringCache()
protected String	newString(char[] cbuf, int off, int len) If feature name interning is enabled then this funtion MUST return interned string.

Constructor Detail

MXParserCachingStrings

public MXParserCachingStrings()

Method Detail

clone

public Object clone()
             throws CloneNotSupportedException

Overrides:

clone in class Object

Throws:

CloneNotSupportedException

setFeature

public void setFeature(String name,
              boolean state)
                throws XmlPullParserException

This allows to change name iterning property in this enhanced impl.

Specified by:

setFeature in interface XmlPullParser

Overrides:

setFeature in class MXParser

Parameters:

name - a String

state - a boolean

Throws:

XmlPullParserException - If the feature is not supported or can not be set

getFeature

public boolean getFeature(String name)

Description copied from class: MXParser

Unknown properties are always returned as false

Specified by:

getFeature in interface XmlPullParser

Overrides:

getFeature in class MXParser

Parameters:

name - The name of feature to be retrieved.

Returns:

The value of the feature.

finalize

public void finalize()

Hook to GC finalization to print statistics about pool cache impl. perf.

Overrides:

finalize in class Object

newString

protected String newString(char[] cbuf,
               int off,
               int len)

If feature name interning is enabled then this funtion MUST return interned string.

Overrides:

newString in class MXParser

newStringIntern

protected String newStringIntern(char[] cbuf,
                     int off,
                     int len)

This is efficient implementation of pool that returns interned String based on char[] input.

Overrides:

newStringIntern in class MXParser

initStringCache

protected void initStringCache()

resetStringCache

protected void resetStringCache()

Overrides:

resetStringCache in class MXParser
