Class AsciiLineReader

java.lang.Object

htsjdk.tribble.readers.AsciiLineReader

All Implemented Interfaces:

LocationAware, LineReader, java.io.Closeable, java.lang.AutoCloseable

public class AsciiLineReader
extends java.lang.Object
implements LineReader, LocationAware

A simple class that provides readLine() functionality around a PositionalBufferedStream BufferedReader and its BufferedReader.readLine() method should be used in preference to this class (when the LocationAware functionality is not required) because it offers greater performance.

Method Detail

getPosition

public long getPosition()

Description copied from interface: LocationAware

The current offset, in bytes, of this stream/writer/file. Or, if this is an iterator/producer, the offset (in bytes) of the END of the most recently returned record (since a produced record corresponds to something that has been read already). See class javadoc for more. Note that for BGZF files, this does not represent an actually file position, but a virtual file pointer.

Specified by:

getPosition in interface LocationAware

Returns:

The position of the InputStream

readLine

public final java.lang.String readLine(PositionalBufferedStream stream)
                                throws java.io.IOException

Read a line of text. A line is considered to be terminated by any one of a line feed ('\n'), a carriage return ('\r'), or a carriage return followed immediately by a linefeed.

Parameters:

stream - the stream to read the next line from

Returns:

A String containing the contents of the line or null if the end of the stream has been reached

Throws:

java.io.IOException

readLine

public final java.lang.String readLine()
                                throws java.io.IOException

Same as readLine(PositionalBufferedStream) but uses the stream provided in the constructor

Specified by:

readLine in interface LineReader

Returns:

Throws:

java.io.IOException

public void close()

Specified by:

close in interface LineReader

Specified by:

close in interface java.io.Closeable

Specified by:
