The methods of the Field class are listed below. For a complete list of Field class members, see the Field Members topic.
![]() | Obsolete. The value of the field in Binary, or null. If null, the Reader value, String value, or TokenStream value is used. Exactly one of stringValue(), readerValue(), GetBinaryValue(), and tokenStreamValue() must be set. |
![]() | Determines whether the specified Object is equal to the current Object. |
![]() | Returns the length of byte[] segment that is used as value. If Field is not binary returned value is undefined. |
![]() | Returns offset into byte[] segment that is used as value. If Field is not binary returned value is undefined. |
![]() | Overloaded. Return the raw byte[] for the binary field. Note that you must also call {@link #GetBinaryLength} and {@link #GetBinaryOffset} to know which range of bytes in this returned array belong to the field. |
![]() | |
![]() | Serves as a hash function for a particular type. GetHashCode is suitable for use in hashing algorithms and data structures like a hash table. |
![]() | True if norms are omitted for this indexed field |
![]() | Returns true if tf is omitted for this indexed field. |
![]() | Gets the Type of the current instance. |
![]() | True iff the value of the filed is stored as binary |
![]() | True if the value of the field is stored and compressed within the index |
![]() | True iff the value of the field is to be indexed, so that it may be searched on. |
![]() | |
![]() | True iff the value of the field is to be stored in the index for return with search hits. It is an error for this to be true if a field is Reader-valued. |
![]() | True iff terms are stored as term vector together with their offsets (start and end positon in source text). |
![]() | True iff terms are stored as term vector together with their token positions. |
![]() | True iff the term or terms used to index this field are stored as a term vector, available from {@link Lucene.Net.Index.IndexReader#GetTermFreqVector(int,String)}. These methods do not provide access to the original content of the field, only to terms used to index it. If the original content must be preserved, use the storedattribute instead. |
![]() | True iff the value of the field should be tokenized as text prior to indexing. Un-tokenized fields are indexed as a single word and may not be Reader-valued. |
![]() | Returns the name of the field as an interned string. For example "date", "title", "body", ... |
![]() | The value of the field as a Reader, or null. If null, the String value, binary value, or TokenStream value is used. Exactly one of stringValue(), readerValue(), getBinaryValue(), and tokenStreamValue() must be set. |
![]() | |
![]() | Expert: If set, omit normalization factors associated with this indexed field. This effectively disables indexing boosts and length normalization for this field. |
![]() | Expert: If set, omit tf from postings of this indexed field. |
![]() | Overloaded. Expert: change the value of this field. This can be used during indexing to re-use a single Field instance to improve indexing speed by avoiding GC cost of new'ing and reclaiming Field instances. Typically a single {@link Document} instance is re-used as well. This helps most on small documents. Note that you should only use this method after the Field has been consumed (ie, the {@link Document} containing this Field has been added to the index). Also, each Field instance should only be used once within a single {@link Document} instance. See ImproveIndexingSpeed for details. |
![]() | The value of the field as a String, or null. If null, the Reader value, binary value, or TokenStream value is used. Exactly one of stringValue(), readerValue(), getBinaryValue(), and tokenStreamValue() must be set. |
![]() | The value of the field as a TokesStream, or null. If null, the Reader value, String value, or binary value is used. Exactly one of stringValue(), readerValue(), GetBinaryValue(), and tokenStreamValue() must be set. |
![]() | Prints a Field for human consumption. |
