An Index maps document names to their referenced words in various categories. Queries can search a single category or several at the same time. Indexes are not synchronized structures and should only be queried/updated one at a time.

Field Summary

java.lang.String	containerPath
protected DiskIndex	diskIndex
protected MemoryIndex	memoryIndex
ReadWriteMonitor	monitor
char	separator

Constructor Summary

Index(java.lang.String fileName, java.lang.String containerPath, boolean reuseExistingFile)

Method Summary

void	addIndexEntry(char[] category, char[] key, java.lang.String containerRelativePath)
java.lang.String	containerRelativePath(java.lang.String documentPath)
java.io.File	getIndexFile()
boolean	hasChanged()
boolean	isIndexForJar()
static boolean	isMatch(char[] pattern, char[] word, int matchRule)
EntryResult[]	query(char[][] categories, char[] key, int matchRule) Returns the entries containing the given key in a group of categories, or null if no matches are found.
java.lang.String[]	queryDocumentNames(java.lang.String substring) Returns the document names that contain the given substring, if null then returns all of them.

Constructor Detail

Index

public Index(java.lang.String fileName,
             java.lang.String containerPath,
             boolean reuseExistingFile)
      throws java.io.IOException

Throws:

java.io.IOException

Method Detail

isMatch

public static boolean isMatch(char[] pattern,
                              char[] word,
                              int matchRule)

addIndexEntry

public void addIndexEntry(char[] category,
                          char[] key,
                          java.lang.String containerRelativePath)

containerRelativePath

public java.lang.String containerRelativePath(java.lang.String documentPath)

getIndexFile

public java.io.File getIndexFile()

hasChanged

public boolean hasChanged()

query

public EntryResult[] query(char[][] categories,
                           char[] key,
                           int matchRule)
                    throws java.io.IOException

Returns the entries containing the given key in a group of categories, or null if no matches are found. The matchRule dictates whether its an exact, prefix or pattern match, as well as case sensitive or insensitive. If the key is null then all entries in specified categories are returned.

Throws:

java.io.IOException

queryDocumentNames

public java.lang.String[] queryDocumentNames(java.lang.String substring)
                                      throws java.io.IOException

Returns the document names that contain the given substring, if null then returns all of them.

Throws:

java.io.IOException

remove

public void remove(java.lang.String containerRelativePath)

reset

public void reset()
           throws java.io.IOException

Reset memory and disk indexes.

Throws:

java.io.IOException

save

public void save()
          throws java.io.IOException

Throws:

java.io.IOException

startQuery

public void startQuery()

stopQuery

public void stopQuery()

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

isIndexForJar
