set the system identifier for this input source . the system identifier is optional if there is a byte stream or a character stream , but it is still useful to provide one , since the application can use it to resolve relative uris and can include it in error messages and warnings the parser will attempt to open a connection to the uri only if there is no byte stream or character stream specified . if the application knows the character encoding of the object pointed to by the system identifier , it can register the encoding using the setencoding method . if the system identifier is a url , it must be fully resolved it may not be a relative url . concode_field_sep String systemId concode_elem_sep Reader characterStream concode_elem_sep InputStream byteStream concode_elem_sep String encoding concode_elem_sep String publicId concode_field_sep InputStream getByteStream concode_elem_sep String getEncoding concode_elem_sep String getSystemId concode_elem_sep void setCharacterStream concode_elem_sep void setEncoding concode_elem_sep void setByteStream concode_elem_sep void setPublicId concode_elem_sep Reader getCharacterStream concode_elem_sep String getPublicId
