Class XMLInputSource

java.lang.Object
  org.apache.uima.util.XMLInputSource

public class XMLInputSource
extends Object

An input source used by the XMLParser to read XML documents for parsing.

The application uses the XMLInputSource(File) constructor to create an XMLInputSource from a descriptor File. Alternatively, if the source of the XML is not a file, the XMLInputSource(InputStream,File) constructor may be used to read the XML from an input stream. The second argument to this constructor is the relative path base, to be used if the descriptor contains imports with relative paths. It is acceptable to set this to null if it is known that the descriptor does not contain any such imports.

Constructor Summary

XMLInputSource(File aFile)
Creates an XMLInputSource from a descriptor file.

XMLInputSource(InputStream aInputStream, File aRelativePathBase)
Creates an XMLInputSource from an existing InputStream.

XMLInputSource(String aUrlOrFileName)
Creates an XMLInputSource from a descriptor file.

XMLInputSource(URL aURL)
Creates an XMLInputSource from a URL.

Method Summary

void	close() Closes the underlying InputStream.
InputStream	getInputStream() Gets the InputStream from which to read an XML document.
File	getRelativePathBase() Deprecated. Use getURL() instead.
URL	getURL() Gets the base for resolving relative paths.
