Class SortedRangeValueList<T>

A sorted list with RangeValuePair<T> ordered by the start index of the ranges. SortedRangeValueList ensures that ranges of the elements inside the list do not overlap and it also ensures that there are no empty gaps meaning that the subsequent range will always have the Start position be set to the End position of the previous range plus one.

Constructors

SortedRangeValueList()

Initializes a new instance of the SortedRangeValueList<T> class.

Declaration
public SortedRangeValueList()

SortedRangeValueList(T)

Initializes a new instance of the SortedRangeValueList<T> class.

Declaration
public SortedRangeValueList(T defaultValue)
Parameters
Type Name Description
T defaultValue

The default value used for filling gaps.

Properties

Count

Gets the count which is the same as the end position of the last range.

Declaration
public int Count { get; }
Property Value
Type Description
System.Int32

The count.

DefaultValue

Gets or sets the default value used for filling gaps.

Declaration
public T DefaultValue { get; set; }
Property Value
Type Description
T

The default value.

Item[Int32]

Gets the value of the range that contains the specified index or changes the value of the range. When necessary it splits a range and creates a new range value pair to hold the new value for the specified index.

Declaration
public T this[int index] { get; set; }
Parameters
Type Name Description
System.Int32 index
Property Value
Type
T

Methods

GetEnumerator()

Returns an enumerator that iterates through a collection.

Declaration
public IEnumerator GetEnumerator()
Returns
Type Description
System.Collections.IEnumerator

An System.Collections.IEnumerator object that can be used to iterate through the collection.

GetRange(Int32, out Int32)

Gets a range that contains the specified index and also returns a count indicating the delta between the index and the end of the range.

Declaration
public T GetRange(int index, out int count)
Parameters
Type Name Description
System.Int32 index

The index.
System.Int32 count

The count.
Returns
Type
T

Insert(Int32, Int32)

Inserts a range intialized with DefaultValue at the specified index. When necessary it splits a range and creates a new range value pair.

Declaration
public void Insert(int insertAt, int count)
Parameters
Type Name Description
System.Int32 insertAt

The insertion point.
System.Int32 count

The count.

Insert(Int32, Int32, T)

Inserts a range intialized with a given value at the specified index. When necessary it splits a range and creates a new range value pair.

Declaration
public void Insert(int insertAt, int count, T value)
Parameters
Type Name Description
System.Int32 insertAt

The insertion point.
System.Int32 count

The count.
T value

The value.

Insert(Int32, Int32, T, SortedRangeValueList<T>)

Inserts a range intialized with a given value at the specified index. When necessary it splits a range and creates a new range value pair.

Declaration
public void Insert(int insertAt, int count, T value, SortedRangeValueList<T> moveRanges)
Parameters
Type Name Description
System.Int32 insertAt

The insertion point.
System.Int32 count

The count.
T value

The value.
SortedRangeValueList<T> moveRanges

Allocate this object before a preceeding Remove call when moving ranges. Otherwise specify null.

Insert(Int32, Int32, SortedRangeValueList<T>)

Inserts a range intialized with DefaultValue at the specified index. When necessary it splits a range and creates a new range value pair.

Declaration
public void Insert(int insertAt, int count, SortedRangeValueList<T> moveRanges)
Parameters
Type Name Description
System.Int32 insertAt

The insertion point.
System.Int32 count

The count.
SortedRangeValueList<T> moveRanges

Allocate this object before a preceeding Remove call when moving ranges. Otherwise specify null.

Remove(Int32, Int32)

Removes a range at the specified index. When necessary ranges are merged when preceeding and subsquent ranges have the same value.

Declaration
public void Remove(int removeAt, int count)
Parameters
Type Name Description
System.Int32 removeAt

The index for the range to be removed.
System.Int32 count

The count.

Remove(Int32, Int32, SortedRangeValueList<T>)

Removes a range at the specified index. When necessary ranges are merged when preceeding and subsquent ranges have the same value.

Declaration
public void Remove(int removeAt, int count, SortedRangeValueList<T> moveRanges)
Parameters
Type Name Description
System.Int32 removeAt

The index for the range to be removed.
System.Int32 count

The count.
SortedRangeValueList<T> moveRanges

Allocate this object before a Remove call when moving ranges and pass it to a subsequent Insert call. Otherwise specify null.

SetRange(Int32, Int32, T)

Sets the value for a range at the specified index. When necessary ranges are split or merged to make sure integrity of the list is maintained. (SortedRangeValueList ensures that ranges of the elements inside the list do not overlap and it also ensures that there are no empty gaps meaning that the subsequent range will always have the Start position be set to the End position of the previous range plus one.)

Declaration
public void SetRange(int index, int count, T value)
Parameters
Type Name Description
System.Int32 index

The index for the range to be changed.
System.Int32 count

The count.
T value

The value.

Declaration
IEnumerator<RangeValuePair<T>> IEnumerable<RangeValuePair<T>>.GetEnumerator()
Returns
Type Description
System.Collections.Generic.IEnumerator<RangeValuePair<T>>

A enumerator that can be used to iterate through the collection.

Implements

System.Collections.Generic.IEnumerable<T>
