Indicates whether the Source object has a Reader instance.- Parameters:
src
- the Source object- Returns:
- true if an Reader is available
-
removeStreams
public static void removeStreams(javax.xml.transform.Source src)
Removes any references to InputStreams or Readers from the given Source to prohibit accidental/unwanted use by a component further downstream.- Parameters:
src
- the Source object
-
closeQuietly
public static void closeQuietly(javax.xml.transform.Source src)
