Class TextLineReader  

java.lang.Object
  org.sourcejammer.server.source.TextLineIteratorOutput
      org.sourcejammer.server.source.TextLineReader

All Implemented Interfaces:

java.io.Serializable, TextLineIterator

public class TextLineReader

extends TextLineIteratorOutput

implements java.io.Serializable

Title: $FileName: TextLineReader.java$

Version:

$VerNum: 3$ $KeyWordsOff: $

This class reads and outputs lines of text from a binary file passed to it as a byte array. It is not necessary to pass the end of line characters to this class. It can determine the end of a line whether the end of line is represented by line feed or carriage return / line feed.

Note: TextLineReader returns text lines without any end of line characters.

Constructor Summary

TextLineReader(java.io.BufferedInputStream st)           Constructs a TextLineReader to read the bytes from the passed in InputStream.

TextLineReader(byte[] buf)           Constructs a TextLineReader from the passed-in byte array.

TextLineReader(byte[] buf, int offset, int length)           Constructs a TextLineReader from the specified bytes in the passed-in byte array.

TextLineReader(java.util.Vector vec)           Constructs a new NextLineReader explicitly setting the underlying Vector to a Vector of Strings.

 

Method Summary
boolean	equals(java.lang.Object o)           Returns true if the the object is a TextLineReader and the current line of the object is equal to the current line of this TextLineReader.
java.lang.String	getCurrentLine()           Returns the current line without adavancing the iterator.
int	getIndex()
java.lang.String	getLine(int index)           Returns the line with the specified index.
java.lang.String	getNextLine()           Returns the next line and advances the index.
int	getNumLines()           Returns the number of lines in the TextLineReader.
java.util.Vector	getUnderlyingVector()
boolean	hasMoreLines()           Returns true if the TextLineReader contains additional lines after the current index.
void	init()           Initializes the TextLineReader.
void	initIgnoreKeywords()           This init method never looks for keywords, so it's a little faster than the other init() if you know you don't need to expand, such as when you're reading a file to return to the user.
static void	main(java.lang.String[] args)
boolean	next()           Advances the iterator to the next line.
void	setExpandKeywords(boolean b)
void	setIndex(int index)           Sets the index to the specified line number.
void	setProjectObjects(org.sourcejammer.server.keywords.ProjectObjects o)
int	size()           Returns the total number of characters in all the lines in this TextLineReader.
void	skipLines(int numLines)           Moves the index ahead by the specified number of lines.
char[]	toCharArray()
char[]	toCharArray(java.lang.String eol)
void	toStream(java.io.OutputStream stream)
void	toStream(java.io.OutputStream stream, java.lang.String eol)
java.lang.String	toString()           Returns contents of this TextLineReader (the entire text file) as a String, the default end of line chars (from AppConfig) as the end of line String.
java.lang.String	toString(java.lang.String eol)           Returns contents of this TextLineReader (the entire text file) as a String, using the passed in eol as the end of line String.
java.lang.StringBuffer	toStringBuffer(java.lang.String eol)           Returns contents of this TextLineReader (the entire text file) as a StringBuffer, using the passed in eol as the end of line String.

Constructor Detail

TextLineReader

public TextLineReader(byte[] buf)
               throws java.io.IOException

Constructs a TextLineReader from the passed-in byte array.

---

TextLineReader

public TextLineReader(java.util.Vector vec)

Constructs a new NextLineReader explicitly setting the underlying Vector to a Vector of Strings. Used for storing the contents of a TextLineReader object without explicitly serializing this object. Vector is serialized instead.

---

TextLineReader

public TextLineReader(byte[] buf,
                      int offset,
                      int length)
               throws java.io.IOException

Constructs a TextLineReader from the specified bytes in the passed-in byte array.

---

TextLineReader

public TextLineReader(java.io.BufferedInputStream st)
               throws java.io.IOException

Constructs a TextLineReader to read the bytes from the passed in InputStream.

Method Detail

setExpandKeywords

public void setExpandKeywords(boolean b)

---

setProjectObjects

public void setProjectObjects(org.sourcejammer.server.keywords.ProjectObjects o)

---

initIgnoreKeywords

public void initIgnoreKeywords()
                        throws java.io.IOException

This init method never looks for keywords, so it's a little faster than the other init() if you know you don't need to expand, such as when you're reading a file to return to the user.

---

init

public void init()
          throws java.io.IOException,
                 org.sourcejammer.server.keywords.KeywordExpansionException

Initializes the TextLineReader. Reads all of the bytes from the InputStream and converts them to lines of text stored in a Vector. No need call if this class was constructed with Vector constructor. This init() method looks for keywords to expand as it reads.
