    • Method Detail

      • getName

        public java.lang.String getName()
        Description copied from class: DataSource
        Returns a name for this source. This name is mainly intended as a label identifying the source for use in informational messages; it is not in general intended to be used to provide an absolute reference to the source. Thus, for instance, if the source references a file, its name might be a relative pathname or simple filename, rather than its absolute pathname. To identify the source absolutely, the DataSource.getURL() method (or some suitable class-specific method) should be used. If this source has a position, it should probably form part of this name.
        Overrides:
        getName in class DataSource
        Returns:
        a name
      • getRawInputStream

        public java.io.InputStream getRawInputStream()
        Description copied from class: DataSource
        Provides a new InputStream for this data source. This method should be implemented by subclasses to provide a new InputStream giving the raw content of the source each time it is called. The general contract of this method is that each time it is called it will return a stream with the same content.
        Specified by:
        getRawInputStream in class DataSource
        Returns:
        an InputStream containing the data of this source
      • getRawLength

        public long getRawLength()
        Description copied from class: DataSource
        Returns the length in bytes of the stream returned by getRawInputStream, if known. If the length is not known then -1 should be returned. The implementation of this method in DataSource returns -1; subclasses should override it if they can determine their length.
        Overrides:
        getRawLength in class DataSource
        Returns:
        the length of the raw input stream, or -1
