Constructor Detail

• ByteArrayDataSource

  public ByteArrayDataSource​(java.lang.String name,
                             byte[] buffer)

  Constructor.

  Parameters:

  name - data source name

  buffer - containing byte content of the source

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
