## Class InstallationDescriptorHandler

- java.lang.Object
- - org.xml.sax.helpers.DefaultHandler
  - - org.apache.uima.pear.tools.InstallationDescriptorHandler

- All Implemented Interfaces:
    ContentHandler, DTDHandler, EntityResolver, ErrorHandler

      public class InstallationDescriptorHandler
      extends DefaultHandler

  The `InstallationDescriptorHandler` class allows parsing XML installation descriptor files, creating instances of the `InstallationDescriptor` class. The `InstallationDescriptorHandler` class also allows to save existing `InstallationDescriptor` objects as XML files.
