Searches for the specified Object and returns the zero-based index of the first occurrence within the range of elements in the ArrayList that starts at the specified index and contains the specified number of elements.
(Inherited from ArrayList.)
Public methodInfo
Public methodInsert
Inserts an element into the ArrayList at the specified index.
(Inherited from ArrayList.)
Public methodInsertRange
Inserts the elements of a collection into the ArrayList at the specified index.
(Inherited from ArrayList.)
Public methodLastIndexOf(Object)

(Inherited from ArrayList.)
Public methodLastIndexOf(Object, Int32)
Searches for the specified Object and returns the zero-based index of the last occurrence within the range of elements in the ArrayList that extends from the first element to the specified index.
(Inherited from ArrayList.)
Public methodLastIndexOf(Object, Int32, Int32)
Searches for the specified Object and returns the zero-based index of the last occurrence within the range of elements in the ArrayList that contains the specified number of elements and ends at the specified index.
(Inherited from ArrayList.)
Protected methodMemberwiseClone
Creates a shallow copy of the current Object.
(Inherited from Object.)
Public methodRange
Returns a new SegmentInfos containg the SegmentInfo instances in the specified range first (inclusive) to last (exclusive), so total number of segments returned is last-first.
Public methodRead(Directory)
This version of read uses the retry logic (for lock-less commits) to find the right segments file to load.
Public methodRead(Directory, String)
Read a particular segmentFileName. Note that this may throw an IOException if a commit is in process.
Public methodStatic memberReadCurrentUserData
Returns userData from latest segments file
Public methodStatic memberReadCurrentVersion
Current version number from segments file.
Public methodRemove

Reverses the order of the elements in the entire ArrayList.
(Inherited from ArrayList.)
Public methodReverse(Int32, Int32)
Reverses the order of the elements in the specified range.
(Inherited from ArrayList.)
Public methodSegString
Public methodStatic memberSetDefaultGenFileRetryCount
Advanced: set how many times to try loading the segments.gen file contents to determine current segment generation. This file is only referenced when the primary method (listing the directory) fails.
Public methodStatic memberSetDefaultGenFileRetryPauseMsec
Advanced: set how many milliseconds to pause in between attempts to load the segments.gen file.
Public methodStatic memberSetDefaultGenLookaheadCount

If non-null, information about retries when loading the segments file will be printed to this.
Public methodSetRange
Copies the elements of a collection over a range of elements in the ArrayList.
(Inherited from ArrayList.)
Public methodSort()()()()
Sorts the elements in the entire ArrayList using the IComparable implementation of each element.

Sorts the elements in the entire ArrayList using the specified comparer.
(Inherited from ArrayList.)
Public methodSort(Int32, Int32, IComparer)
Sorts the elements in a range of elements in ArrayList using the specified comparer.
(Inherited from ArrayList.)
Public methodToArray()()()()
Copies the elements of the ArrayList to a new Object array.
(Inherited from ArrayList.)
Public methodToArray(Type)
Copies the elements of the ArrayList to a new array of the specified element type.
(Inherited from ArrayList.)
Public methodToString
Returns a String that represents the current Object.
(Inherited from Object.)
Public methodTrimToSize
Sets the capacity to the actual number of elements in the ArrayList.
(Inherited from ArrayList.)
