Assembly: Extreme.Data (in Extreme.Data.dll) Version: 3.2.0

public class RAttributeCollection : IDictionary<string, RObject>, 
	ICollection<KeyValuePair<string, RObject>>, IEnumerable<KeyValuePair<string, RObject>>, 
	IEnumerable

Visual Basic

Public Class RAttributeCollection
	Implements IDictionary(Of String, RObject), 
	ICollection(Of KeyValuePair(Of String, RObject)), IEnumerable(Of KeyValuePair(Of String, RObject)), 
	IEnumerable

C++/CLI

public ref class RAttributeCollection : IDictionary<String^, RObject^>, 
	ICollection<KeyValuePair<String^, RObject^>>, IEnumerable<KeyValuePair<String^, RObject^>>, 
	IEnumerable

type RAttributeCollection = 
    class
        interface IDictionary<string, RObject>
        interface ICollection<KeyValuePair<string, RObject>>
        interface IEnumerable<KeyValuePair<string, RObject>>

Remarks

Use the RAttributeCollection class to access the attributes of an R object. The class is a dictionary that maps attribute names (strings) to attributes, which can be objects of any type.

Constructors

RAttributeCollection

Constructs a new attribute collection from a dictionary of items.

Properties

Count	Gets the number of attributes in the collection.
IsReadOnly	Gets whether the collection is read-only.
Item	Gets or sets an attribute in the collection.
Keys	Gets a collection of the names of the attributes.
Values	Gets a collection of the values of the attributes.

Methods

Add	Adds a new attribute to the collection.
Clear	Removes all attributes from the collection.
ContainsKey	Returns whether the collection contains an attribute with the specified name.
Equals	Determines whether the specified object is equal to the current object. (Inherited from Object)
Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object)
GetEnumerator	Returns an enumerator that iterates over the attributes in the collection.
GetHashCode	Serves as the default hash function. (Inherited from Object)
GetType	Gets the Type of the current instance. (Inherited from Object)
MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object)
Remove	Removes the attribute with the specified name from the collection.
ToString	Returns a string that represents the current object. (Inherited from Object)
TryGetIntegers	Attempts to get the value of an integer vector attribute.
TryGetString	Attempts to get the value of a string attribute.
TryGetStrings	Attempts to get the value of a string vector attribute.
TryGetValue	Attempts to retrieve the value of the attribute with the specified key from the collection.

Fields

Empty

Represents an empty, read-only attribute collection.

Extension Methods

Group<KeyValuePair<String, RObject>>	Returns a grouping by the unique elements in a sequence. (Defined by Grouping)
Group<KeyValuePair<String, RObject>>	Returns a grouping by the unique elements in a sequence using the specified comparer to determine equality. (Defined by Grouping)
Sum<KeyValuePair<String, RObject>>	Computes the sum of the sequence of values. (Defined by ArrayMath)
Sum<KeyValuePair<String, RObject>, U>	Computes the sum of the sequence of values that are obtained by invoking a transform function on each element of the input sequence. (Defined by ArrayMath)
