The FieldCache type exposes the following members.

Methods

	Name	Description
	GetAuto	Obsolete. Checks the internal cache for an appropriate entry, and if none is found reads CopyC# field to see if it contains integers, longs, floats or strings, and then calls one of the other methods in this class to get the values. For string values, a StringIndex is returned. After calling this method, there is an entry in the cache for both type CopyC# AUTO and the actual found type.
	GetBytes(IndexReader, String)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as a single byte and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetBytes(IndexReader, String, ByteParser)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as bytes and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetCacheEntries	EXPERT: Generates an array of CacheEntry objects representing all items currently in the FieldCache. NOTE: These CacheEntry objects maintain a strong refrence to the Cached Values. Maintaining refrences to a CacheEntry the IndexReader associated with it has garbage collected will prevent the Value itself from being garbage collected when the Cache drops the WeakRefrence. EXPERIMENTAL API: This API is considered extremely advanced and experimental. It may be removed or altered w/o warning in future releases of Lucene.
	GetCustom	Obsolete. Checks the internal cache for an appropriate entry, and if none is found reads the terms out of CopyC# field and calls the given SortComparator to get the sort values. A hit in the cache will happen if CopyC# reader , CopyC# field , and CopyC# comparator are the same (using CopyC# equals() ) as a previous call to this method.
	GetDoubles(IndexReader, String)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as integers and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetDoubles(IndexReader, String, DoubleParser)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as doubles and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetFloats(IndexReader, String)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as floats and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetFloats(IndexReader, String, FloatParser)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as floats and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetInfoStream	counterpart of {@link #SetInfoStream(PrintStream)}
	GetInts(IndexReader, String)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as integers and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetInts(IndexReader, String, IntParser)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as integers and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetLongs(IndexReader, String)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as longs and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetLongs(IndexReader, String, LongParser)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as longs and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetShorts(IndexReader, String)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as shorts and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetShorts(IndexReader, String, ShortParser)	Checks the internal cache for an appropriate entry, and if none is found, reads the terms in CopyC# field as shorts and returns an array of size CopyC# reader.maxDoc() of the value each document has in the given field.
	GetStringIndex	Checks the internal cache for an appropriate entry, and if none is found reads the term values in CopyC# field and returns an array of them in natural order, along with an array telling which element in the term array each document uses.
	GetStrings	Checks the internal cache for an appropriate entry, and if none is found, reads the term values in CopyC# field and returns an array of size CopyC# reader.maxDoc() containing the value each document has in the given field.
	Purge	Expert: drops all cache entries associated with this reader. NOTE: this reader must precisely match the reader that the cache entry is keyed on. If you pass a top-level reader, it usually will have no effect as Lucene now caches at the segment reader level.
	PurgeAllCaches	EXPERT: Instructs the FieldCache to forcibly expunge all entries from the underlying caches. This is intended only to be used for test methods as a way to ensure a known base state of the Cache (with out needing to rely on GC to free WeakReferences). It should not be relied on for "Cache maintenance" in general application code. EXPERIMENTAL API: This API is considered extremely advanced and experimental. It may be removed or altered w/o warning in future releases of Lucene.
	SetInfoStream	If non-null, FieldCacheImpl will warn whenever entries are created that are not sane according to {@link Lucene.Net.Util.FieldCacheSanityChecker}.
