Method Details

getName
Description copied from class:DataSourceReturns 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, theDataSource.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:
getNamein classDataSource- Returns:
- a name
-
getRawInputStream
Description copied from class:DataSourceProvides 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:
getRawInputStreamin classDataSource- Returns:
- an InputStream containing the data of this source
-
getRawLength
public long getRawLength()Description copied from class:DataSourceReturns the length in bytes of the stream returned bygetRawInputStream, if known. If the length is not known then -1 should be returned. The implementation of this method inDataSourcereturns -1; subclasses should override it if they can determine their length.- Overrides:
getRawLengthin classDataSource- Returns:
- the length of the raw input stream, or -1
