Method Summary

Modifier and Type	Method	Description
void	clear()
String	getContent()	Returns a dictionary string with containing all unwritten content note: unnecessary writes are important as there is a device specific initgraphics call by the underlying postscript interpreter on every setpagedevice call which can result in blank pages etc.
boolean	isEmpty()	Returns true if this map contains no key-value mappings.
Object	put(Object key, Object value)
void	putAll(Map m)
void	setFlushOnRetrieval(boolean flushOnRetrieval)	The contents of the dictionary are flushed when written
