MacroSubstitutionDelegate<T> Delegate

Summary

Provides a delegate type to be used to process a macro.

Syntax

C++

public delegate string MacroSubstitutionDelegate( 
   T item, 
   string name, 
   object[] parameters 
)

Public Delegate Function MacroSubstitutionDelegate(Of T)( _ 
   ByVal item As T, _ 
   ByVal name As String, _ 
   ByVal ParamArray parameters() As Object _ 
) As String

generic<typename T> 
public delegate String^ MacroSubstitutionDelegate(  
   _T^_ item, 
   String^ name, 
   ... array<Object^>^ parameters 
)

Parameters

item The user data passed to the macro process.

name The name of the macro.

parameters The parameters passed to the macro.

Type Parameters

T
Type of user item being passed to the macro process.

Return Value

A string that represents the macro.

Example

This example adds two macros to the macro processor and processes a string.

using Leadtools.Dicom.Common.Anonymization; 
 
 
public void MacroProcessorSample() 
{ 
   MacroProcessor<object> processor = new MacroProcessor<object>(); 
 
   // 
   // add two macros to the macro processor 
   // 
   processor.Macros.Add("current_date", new MacroSubstitutionDelegate<object>(CurrentDateMacro)); 
   processor.Macros.Add("current_time", new MacroSubstitutionDelegate<object>(CurrentTimeMacro)); 
 
   // 
   // Process a macro string 
   // 
   Console.WriteLine(processor.Process(processor, "${current_date} ==> ${current_time}")); 
} 
 
private string CurrentDateMacro(object userData, string name, params object[] parameters) 
{ 
   return DateTime.Now.ToShortDateString(); 
} 
 
private string CurrentTimeMacro(object userData, string name, params object[] parameters) 
{ 
   return DateTime.Now.ToShortTimeString(); 
}
