Class HTTPInputSource

java.lang.Object
org.apache.xerces.xni.parser.XMLInputSource
org.apache.xerces.util.HTTPInputSource

public final class HTTPInputSource extends org.apache.xerces.xni.parser.XMLInputSource
This class represents an input source for an XML resource retrievable over HTTP. In addition to the properties provided by an XMLInputSource an HTTP input source also has HTTP request properties and a preference whether HTTP redirects will be followed. Note that these properties will only be used if reading this input source will induce an HTTP connection.

    Description
    HTTPInputSource(String publicId, String systemId, String baseSystemId)
    Constructs an input source from just the public and system identifiers, leaving resolution of the entity and opening of the input stream up to the caller.
    HTTPInputSource(String publicId, String systemId, String baseSystemId, InputStream byteStream, String encoding)
    Constructs an input source from a byte stream.
    HTTPInputSource(String publicId, String systemId, String baseSystemId, Reader charStream, String encoding)
    Constructs an input source from a character stream.
    HTTPInputSource(org.apache.xerces.xni.XMLResourceIdentifier resourceIdentifier)
    Constructs an input source from a XMLResourceIdentifier object, leaving resolution of the entity and opening of the input stream up to the caller.

    • HTTPInputSource

      public HTTPInputSource(String publicId, String systemId, String baseSystemId)
      Constructs an input source from just the public and system identifiers, leaving resolution of the entity and opening of the input stream up to the caller.
      Parameters:
      publicId - The public identifier, if known.
      systemId - The system identifier. This value should always be set, if possible, and can be relative or absolute. If the system identifier is relative, then the base system identifier should be set.
      baseSystemId - The base system identifier. This value should always be set to the fully expanded URI of the base system identifier, if possible.
    • HTTPInputSource

      public HTTPInputSource(org.apache.xerces.xni.XMLResourceIdentifier resourceIdentifier)
      Constructs an input source from a XMLResourceIdentifier object, leaving resolution of the entity and opening of the input stream up to the caller.
      Parameters:
      resourceIdentifier - the XMLResourceIdentifier containing the information
    • HTTPInputSource

      public HTTPInputSource(String publicId, String systemId, String baseSystemId, InputStream byteStream, String encoding)
      Constructs an input source from a byte stream.
      Parameters:
      publicId - The public identifier, if known.
      systemId - The system identifier. This value should always be set, if possible, and can be relative or absolute. If the system identifier is relative, then the base system identifier should be set.
      baseSystemId - The base system identifier. This value should always be set to the fully expanded URI of the base system identifier, if possible.
      byteStream - The byte stream.
      encoding - The encoding of the byte stream, if known.
