Constructor Detail

SearchDocument

protected SearchDocument(String documentPath,
                         SearchParticipant participant)
Creates a new search document. The given document path is a string that uniquely identifies the document. Most of the time it is a workspace-relative path, but it can also be a file system path, or a path inside a zip file.

Parameters:
documentPath - the path to the document, or null if none
participant - the participant that creates the search document
Method Detail

addIndexEntry

public void addIndexEntry(char[] category,
                          char[] key)
Adds the given index entry (category and key) coming from this document to the index. This method must be called from SearchParticipant.indexDocument(SearchDocument document, org.eclipse.core.runtime.IPath indexPath).

Parameters:
category - the category of the index entry
key - the key of the index entry

getByteContents

public abstract byte[] getByteContents()
Returns the contents of this document. Contents may be different from actual resource at corresponding document path, in case of preprocessing.

This method must be implemented in subclasses.

Note: some implementation may choose to cache the contents directly on the document for performance reason. However, this could induce scalability issues due to the fact that collections of documents are manipulated throughout the search operation, and cached contents would then consume lots of memory until they are all released at once in the end.

Returns:
the contents of this document, or null if none

getCharContents

public abstract char[] getCharContents()
Returns the contents of this document. Contents may be different from actual resource at corresponding document path due to preprocessing.

This method must be implemented in subclasses.

Note: some implementation may choose to cache the contents directly on the document for performance reason. However, this could induce scalability issues due to the fact that collections of documents are manipulated throughout the search operation, and cached contents would then consume lots of memory until they are all released at once in the end.

Returns:
the contents of this document, or null if none

getEncoding

public abstract String getEncoding()
Returns the encoding for this document.

This method must be implemented in subclasses.

Returns:
the encoding for this document, or null if none

getParticipant

public final SearchParticipant getParticipant()
Returns the participant that created this document.

Returns:
the participant that created this document

getPath

public final String getPath()
Returns the path to the original document to publicly mention in index or search results. This path is a string that uniquely identifies the document. Most of the time it is a workspace-relative path, but it can also be a file system path, or a path inside a zip file.

Returns:
the path to the document

removeAllIndexEntries

public void removeAllIndexEntries()
Removes all index entries from the index for the given document. This method must be called from SearchParticipant.indexDocument(SearchDocument document, org.eclipse.core.runtime.IPath indexPath).
