Syntax

public class FRWriter : IDisposable

Constructors

FRWriter()

Initializes a new instance of the FRWriter class with default settings.

Declaration

public FRWriter()

FRWriter(XmlItem)

Initializes a new instance of the FRWriter class with specified xml item that will receive writer's output.

Declaration

public FRWriter(XmlItem root)

Parameters

Type	Name	Description
XmlItem	root	The xml item that will receive writer's output.

Properties

DiffObject

Gets the ethalon object to compare with.

Declaration

public object DiffObject { get; }

Property Value

Type	Description
System.Object

ItemName

Gets or sets current xml item name.

Declaration

public string ItemName { get; set; }

Property Value

Type	Description
System.String

SaveChildren

Gets or sets a value that determines whether is necessary to serialize child objects.

Declaration

public bool SaveChildren { get; set; }

Property Value

Type	Description
System.Boolean

SerializeTo

Gets or sets target of serialization.

Declaration

public SerializeTo SerializeTo { get; set; }

Property Value

Type	Description
SerializeTo

WriteHeader

Gets or sets a value that determines whether is necessary to add xml header.

Declaration

public bool WriteHeader { get; set; }

Property Value

Type	Description
System.Boolean

Methods

AreEqual(Object, Object)

Determines if two objects are equal.

Declaration

public bool AreEqual(object obj1, object obj2)

Parameters

Type	Name	Description
System.Object	obj1	The first object.
System.Object	obj2	The second object.

Returns

Type	Description
System.Boolean	true if objects will be serialized to the same value.

Dispose()

Disposes the writer.

Declaration

public void Dispose()

Save(Stream)

Saves the writer output to a stream.

Declaration

public void Save(Stream stream)

Parameters

Type	Name	Description
System.IO.Stream	stream	Stream to save to.

Write(IFRSerializable)

Serializes the specified object.

Declaration

public void Write(IFRSerializable obj)

Parameters

Type	Name	Description
IFRSerializable	obj	The object to serialize.

Remarks

The object must implement the IFRSerializable interface. This method invokes the Serialize method of the object.

Examples

This example demonstrates the use of writer.

public void Serialize(FRWriter writer)
{
  // get the etalon object. It will be used to write changed properties only.
  Base c = writer.DiffObject as Base;

  // write the type name
  writer.ItemName = ClassName;

  // write properties
  if (Name != "")
    writer.WriteStr("Name", Name);
  if (Restrictions != c.Restrictions)
    writer.WriteValue("Restrictions", Restrictions);

  // write child objects if allowed
  if (writer.SaveChildren)
  {
    foreach (Base child in ChildObjects)
    {
      writer.Write(child);
    }
  }
}
