DynamicObject

Namespace: Wisej.Core

Assembly: Wisej.Framework (3.5.0.0)

Custom fast implementation of a dynamic object that can handle the JSON serialization and deserialization. This class implements IDynamicMetaObjectProvider allowing the DLR to compile the dynamic member access on the fly. We could have derived from System.Dynamic.Dynamic but the implementation in the .NET framework uses exceptions to manage custom properties.

C#

public class DynamicObject : IDynamicMetaObjectProvider, ICloneable, IList<Member>, ICollection<Member>, IEnumerable<Member>, IEnumerable, ISerializable, ICustomTypeDescriptor, INotifyPropertyChanged, IConvertible

VB.NET

Public Class DynamicObject
    Inherits IDynamicMetaObjectProvider
    Implements ICloneable, IList(Of Member), ICollection(Of Member), IEnumerable(Of Member), IEnumerable, ISerializable, ICustomTypeDescriptor, INotifyPropertyChanged, IConvertible

Constructors

DynamicObject()

Default constructor.

DynamicObject(capacity)

Optional constructor. Takes the initial capacity to allocate the specified number of slots in the store.

Name	Type	Description
capacity	Int32	Initial number of store entries.

DynamicObject(source)

Creates a new DynamicObject cloned from the source object.

Name	Type	Description
source	DynamicObject	Source object to copy the fields from.

Properties

Count

Int32: Returns the number of fields.

IsEmpty

Boolean: Returns true if the dynamic doesn't object contains any field.

Item(name)

Object: Returns or sets the value of the specified member.

Methods

Clear()

Wipes out the object.

Clear(keepCapacity)

Wipes out the object but it keeps the capacity.

Parameter	Type	Description
keepCapacity	Boolean

Clone()

Clones the members of the dynamic object.

Returns: DynamicObject. The cloned instance.

This is a shallow copy. Reference members are copied by reference.

Contains(name)

Returns whether the object contains the specified field.

Parameter	Type	Description
name	String	Name of the field to check.

Returns: Boolean. True if the field name exists in the store.

CopyFrom(source)

Copies all the values from the source object.

Parameter	Type	Description
source	DynamicObject	Object to copy members from.

Delete(name)

Deletes the field.

Parameter	Type	Description
name	String	Name of the field to remove.

Returns: DynamicObject. Itself, this call can be chained.

Diff(original)

Returns a new ComponentConfiguration object containing only the values that don't exist in the ComponentConfiguration object passed to the method.

Parameter	Type	Description
original	DynamicObject	previous values to diff against.

Returns: Object. Returns null if there are no differences.

GetEnumerator()

Returns an enumerator that iterates through the collection.

Returns: IEnumerator<Member>. A IEnumerator

Notify(name)

Fires the PropertyChanged event.

Parameter	Type	Description
name	String	Name of the property that has changed in the dynamic object.

Sort()

Sorts the field by their name.

ToJSON(formatted)

Serializes the object to a JSON string.

Parameter	Type	Description
formatted	Boolean	True to format the output JSON string.

Returns: String. A String representing the serialized object.

ToJSON(options)

Serializes the object to a JSON string.

Parameter	Type	Description
options	WisejSerializerOptions	A combination of WisejSerializerOptions flags.

Returns: String. A String representing the serialized object.

TrimExcess()

Removes the excess entries in the inner array and in all child fields, recursively.

TryGetValue(name, value)

Tries to retrieve the value for the specified member.

Parameter	Type	Description
name	String	Name of the field to retrieve.
value	Object	Will receive the value of the name field.

Returns: Boolean. True if the member was found, otherwise false.
