Public Instance Constructors
FilterIndexReader Constructor
|
Construct a FilterIndexReader based on the specified base reader. Directory locking for delete, undeleteAll, and setNorm operations is left to the base reader. Note that base reader is closed if this FilterIndexReader is closed. |
Public Instance Methods
| Close (inherited from IndexReader) | Closes files associated with this index. Also saves any new deletions to disk. No other methods should be called after this has been called. |
| Delete (inherited from IndexReader) | Overloaded. Deletes the document numbered docNum. Once a document is deleted it will not appear in TermDocs or TermPostitions enumerations. Attempts to read its field with the {@link #document} method will result in an error. The presence of this document may still be reflected in the {@link #docFreq} statistic, though this will be corrected eventually as the index is further modified. |
| DeleteDocument (inherited from IndexReader) | Deletes the document numbered docNum. Once a document is deleted it will not appear in TermDocs or TermPostitions enumerations. Attempts to read its field with the {@link #document} method will result in an error. The presence of this document may still be reflected in the {@link #docFreq} statistic, though this will be corrected eventually as the index is further modified. |
| DeleteDocuments (inherited from IndexReader) | Deletes all documents containing term. This is useful if one uses a document field to hold a unique ID string for the document. Then to delete such a document, one merely constructs a term with the appropriate field and the unique ID string as its text and passes it to this method. See {@link #Delete(int)} for information about when this deletion will become effective. |
| Directory (inherited from IndexReader) | Returns the directory this index resides in. |
| DocFreq | |
| Document | |
| Equals (inherited from Object) | Determines whether the specified Object is equal to the current Object. |
| GetFieldNames | Overloaded. |
| GetHashCode (inherited from Object) | Serves as a hash function for a particular type, suitable for use in hashing algorithms and data structures like a hash table. |
| GetIndexedFieldNames | Overloaded. |
| GetIndexedFieldNames (inherited from IndexReader) | Overloaded. Get a list of unique field names that exist in this index, are indexed, and have the specified term vector information. |
| GetTermFreqVector | |
| GetTermFreqVectors | |
| GetType (inherited from Object) | Gets the Type of the current instance. |
| GetVersion (inherited from IndexReader) | Version number when this IndexReader was opened. |
| HasDeletions | |
| HasNorms | |
| IsCurrent (inherited from IndexReader) | Check whether this IndexReader still works on a current version of the index. If this is not the case you will need to re-open the IndexReader to make sure you see the latest changes made to the index. |
| IsDeleted | |
| MaxDoc | |
| Norms | Overloaded. |
| NumDocs | |
| SetNorm (inherited from IndexReader) | Overloaded. Expert: Resets the normalization factor for the named field of the named document. |
| TermDocs | Overloaded. |
| TermDocs (inherited from IndexReader) | Overloaded. Returns an unpositioned {@link TermDocs} enumerator. |
| TermPositions | Overloaded. |
| TermPositions (inherited from IndexReader) | Overloaded. Returns an unpositioned {@link TermPositions} enumerator. |
| Terms | Overloaded. |
| ToString (inherited from Object) | Returns a String that represents the current Object. |
| UndeleteAll (inherited from IndexReader) | Undeletes all documents currently marked as deleted in this index. |
Protected Instance Methods

| MemberwiseClone (inherited from Object) | Creates a shallow copy of the current Object. |
