  Modifier and Type	Method	Description

• • Method Detail

     * #### setSystemId  
     void setSystemId​([String](../../../java/lang/String.html "class in java.lang") systemId)  
     Set the system identifier for this Source.  
     The system identifier is optional if the source does not get its data from a URL, but it may still be useful to provide one. The application can use a system identifier, for example, to resolve relative URIs and to include in error messages and warnings.  
     Parameters:  
     `systemId` \- The system identifier as a URL string.  
     * #### getSystemId  
     [String](../../../java/lang/String.html "class in java.lang") getSystemId​()  
     Get the system identifier that was set with setSystemId.  
     Returns:  
     The system identifier that was set with setSystemId, or null if setSystemId was not called.  
     * #### isEmpty  
     default boolean isEmpty​()  
     Indicates whether the `Source` object is empty. Empty means that there is no input available from this Source.  
     Implementation Requirements:  
     The default implementation of this method throws[UnsupportedOperationException](../../../java/lang/UnsupportedOperationException.html "class in java.lang").  
     Returns:  
     true if the `Source` object is empty, false otherwise
