Syntax

public class CompositeUpdater : IValueUpdater, IPortableObject

Constructors

CompositeUpdater()

Default constructor.

Declaration

public CompositeUpdater()

CompositeUpdater(string)

Construct a CompositeUpdater for a specified method name sequence.

Declaration

public CompositeUpdater(string name)

Parameters

Type	Name	Description
string	name	A dot-delimited sequence of N method names which results in a CompositeUpdater that is based on an chain of (N-1) ReflectionExtractor objects and a single ReflectionUpdater.

Remarks

For example: "Address.Zip" property will indicate that the "Address" property should be used to extract an Address object, which will then be used by the "Zip" call.

CompositeUpdater(IValueExtractor, IValueUpdater)

Construct a CompositeUpdater based on the specified extractor and updater.

Declaration

public CompositeUpdater(IValueExtractor extractor, IValueUpdater updater)

Parameters

Type	Name	Description
IValueExtractor	extractor	The IValueExtractor.
IValueUpdater	updater	The IValueUpdater.

Remarks

Note: the extractor and updater here are not symmetrical in nature: the extractor is used to "drill-down" to the target object, while the updater will operate on that extracted object.

Fields

m_extractor

The IValueExtractor part.

Declaration

protected IValueExtractor m_extractor

Field Value

Type	Description
IValueExtractor

m_updater

The IValueUpdater part.

Declaration

protected IValueUpdater m_updater

Field Value

Type	Description
IValueUpdater

Properties

Extractor

The IValueExtractor part.

Declaration

public virtual IValueExtractor Extractor { get; }

Property Value

Type	Description
IValueExtractor	The IValueExtractor part.

Updater

The IValueUpdater part.

Declaration

public virtual IValueUpdater Updater { get; }

Property Value

Type	Description
IValueUpdater	The IValueUpdater part.

Methods

Equals(object)

Compare the IValueUpdater with another object to determine equality.

Declaration

public override bool Equals(object o)

Parameters

Type	Name	Description
object	o	The object to compare with.

Returns

Type	Description
bool	true iff this IValueUpdater and the passed object are quivalent IValueUpdaters.

Overrides

object.Equals(object)

GetHashCode()

Determine a hash value for the IValueUpdater object according to the general object.GetHashCode contract.

Declaration

public override int GetHashCode()

Returns

Type	Description
int	An integer hash value for this IValueUpdater object.

Overrides

object.GetHashCode()

ReadExternal(IPofReader)

Restore the contents of a user type instance by reading its state using the specified IPofReader object.

Declaration

public virtual void ReadExternal(IPofReader reader)

Parameters

Type	Name	Description
IPofReader	reader	The IPofReader from which to read the object's state.

Exceptions

Type	Condition
IOException	If an I/O error occurs.

ToString()

Return a human-readable description for this CompositeUpdater.

Declaration

public override string ToString()

Returns

Type	Description
string	A String description of the CompositeUpdater.

Overrides

object.ToString()

Update(object, object)

Update the state of the passed target object using the passed value.

Declaration

public virtual void Update(object target, object value)

Parameters

Type	Name	Description
object	target	The object to update the state of.
object	value	The new value to update the state with.

Exceptions

Type	Condition
InvalidCastException	If this IValueUpdater is incompatible with the passed target object or the value and the implementation requires the passed object or the value to be of a certain type.
ArgumentException	If this IValueUpdater cannot handle the passed target object or value for any other reason; an implementor should include a descriptive message.

WriteExternal(IPofWriter)

Save the contents of a POF user type instance by writing its state using the specified IPofWriter object.

Declaration

public virtual void WriteExternal(IPofWriter writer)

Parameters

Type	Name	Description
IPofWriter	writer	The IPofWriter to which to write the object's state.

Exceptions

Type	Condition
IOException	If an I/O error occurs.
