Class EquatableList<T>

Represents a strongly typed list of objects that can be accessed by index. Provides methods to manipulate lists. Also provides functionality to compare lists against each other through an implementations of , or to wrap an existing list to use the same comparison logic as this one while not affecting any of its other functionality.

Inheritance

EquatableList<T>

Implements

IEquatable<IList<T>>

Namespace: Lucene.Net.Support

Assembly: Lucene.Net.dll

Syntax

public class EquatableList<T> : IList<T>, IEquatable<IList<T>>

Type Parameters

Name	Description
T	The type of elements in the list.

Constructors

EquatableList()

Initializes a new instance of the EquatableList<T> class that is empty and has the default initial capacity.

Declaration

public EquatableList()

EquatableList(IEnumerable<T>)

Initializes a new instance of the EquatableList<T> class that contains elements copied from the specified collection and has sufficient capacity to accommodate the number of elements copied.

Declaration

public EquatableList(IEnumerable<T> collection)

Parameters

Type	Name	Description
IEnumerable<T>	collection	The collection whose elements are copied to the new list.

EquatableList(IList<T>, Boolean)

Initializes a new instance of EquatableList<T>.

If the wrap parameter is true, the collection is used as is without doing a copy operation. Otherwise, the collection is copied (which is the same operation as the EquatableList(IEnumerable<T>) overload).

The internal collection is used for all operations except for Equals(Object), GetHashCode(), and ToString(), which are all based on deep analysis of this collection and any nested collections.

Declaration

public EquatableList(IList<T> collection, bool wrap)

Parameters

Type	Name	Description
IList<T>	collection	The collection that will either be wrapped or copied depending on the value of wrap.
System.Boolean	wrap	true to wrap an existing without copying, or false to copy the collection into a new .

EquatableList(Int32)

Initializes a new instance of the EquatableList<T> class that is empty and has the specified initial capacity.

Declaration

public EquatableList(int capacity)

Parameters

Type	Name	Description
System.Int32	capacity	The number of elements that the new list can initially store.

Properties

Count

Gets the number of elements contained in the EquatableList<T>.

Declaration

public virtual int Count { get; }

Property Value

Type	Description
System.Int32

IsReadOnly

Gets a value indicating whether the EquatableList<T> is read-only.

Declaration

public virtual bool IsReadOnly { get; }

Property Value

Type	Description
System.Boolean

Item[Int32]

Gets or sets the element at the specified index.

Declaration

public virtual T this[int index] { get; set; }

Parameters

Type	Name	Description
System.Int32	index	The zero-based index of the element to get or set.

Property Value

Type	Description
T

Methods

Add(T)

Adds an object to the end of the EquatableList<T>.

Declaration

public virtual void Add(T item)

Parameters

Type	Name	Description
T	item	The object to be added to the end of the EquatableList<T>. The value can be null for reference types.

Clear()

Removes all items from the EquatableList<T>.

Declaration

public virtual void Clear()

Clone()

Clones the EquatableList<T>.

Declaration

public virtual object Clone()

Returns

Type	Description
System.Object	A new shallow clone of this EquatableList<T>.

Remarks

This is a shallow clone.

Contains(T)

Determines whether the EquatableList<T> contains a specific value.

Declaration

public virtual bool Contains(T item)

Parameters

Type	Name	Description
T	item	The object to locate in the EquatableList<T>.

Returns

Type	Description
System.Boolean	true if the Object is found in the EquatableList<T>; otherwise, false.

CopyTo(T[], Int32)

Copies the entire EquatableList<T> to a compatible one-dimensional array, starting at the specified index of the target array.

Declaration

public virtual void CopyTo(T[] array, int arrayIndex)

Parameters

Type	Name	Description
T[]	array	The one-dimensional that is the destination of the elements copied from EquatableList<T>. The Array must have zero-based indexing.
System.Int32	arrayIndex	The zero-based index in array at which copying begins.

Equals(IList<T>)

Compares this sequence to another implementation, returning true if they are equal, false otherwise.

The comparison takes into consideration any values in this collection and values of any nested collections, but does not take into consideration the data type. Therefore, EquatableList<T> can equal any with the exact same values in the same order.

Declaration

public virtual bool Equals(IList<T> other)

Parameters

Type	Name	Description
IList<T>	other	The other implementation to compare against.

Returns

Type	Description
System.Boolean	true if the sequence in other is the same as this one.

Equals(Object)

If the object passed implements , compares this sequence to other, returning true if they are equal, false otherwise.

The comparison takes into consideration any values in this collection and values of any nested collections, but does not take into consideration the data type. Therefore, EquatableList<T> can equal any with the exact same values in the same order.

Declaration

public override bool Equals(object other)

Parameters

Type	Name	Description
System.Object	other	The other object to compare against.

Returns

Type	Description
System.Boolean	true if the sequence in other is the same as this one.

GetEnumerator()

Returns an enumerator that iterates through the EquatableList<T>.

Declaration

public virtual IEnumerator<T> GetEnumerator()

Returns

Type	Description
IEnumerator<T>	An for the EquatableList<T>.

GetHashCode()

Returns the hash code value for this list.

The hash code determination takes into consideration any values in this collection and values of any nested collections, but does not take into consideration the data type. Therefore, the hash codes will be exactly the same for this EquatableList<T> and another (including arrays) with the same values in the same order.

Declaration

public override int GetHashCode()

Returns

Type	Description
System.Int32	the hash code value for this list

IndexOf(T)

Determines the index of a specific item in the EquatableList<T>.

Declaration

public virtual int IndexOf(T item)

Parameters

Type	Name	Description
T	item	The object to locate in the EquatableList<T>.

Returns

Type	Description
System.Int32	The index of item if found in the list; otherwise, -1.

Insert(Int32, T)

Inserts an item to the EquatableList<T> at the specified index.

Declaration

public virtual void Insert(int index, T item)

Parameters

Type	Name	Description
System.Int32	index	The zero-based index at which item should be inserted.
T	item	The object to insert into the EquatableList<T>.

Remove(T)

Removes the first occurrence of a specific object from the EquatableList<T>.

Declaration

public virtual bool Remove(T item)

Parameters

Type	Name	Description
T	item	The object to remove from the EquatableList<T>.

Returns

Type	Description
System.Boolean	true if item was successfully removed from the EquatableList<T>; otherwise, false. This method also returns false if item is not found in the original EquatableList<T>.

RemoveAt(Int32)

Removes the EquatableList<T> item at the specified index.

Declaration

public virtual void RemoveAt(int index)

Parameters

Type	Name	Description
System.Int32	index	The zero-based index of the item to remove.

ToString()

Returns a string representation of this collection (and any nested collections). The string representation consists of a list of the collection's elements in the order they are returned by its enumerator, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", " (comma and space).

Declaration

public override string ToString()

Returns

Type	Description
System.String	a string representation of this collection
