public class MacroProcessor<T>

'Declaration

Public Class MacroProcessor(Of T)

'Usage

Dim instance As MacroProcessor(Of T)

generic<typename T>
public ref class MacroProcessor

T: Type of data passed to the macro substitution delegates.

Macros are defined as ${macro_name} in strings. This class looks for those tokens and calls the appropriate registered delegate to return a string. The MacroProcessor class has the following default macros when created:

Value	Meaning
date	Current date.
random_string	Random string of specified link.
random_date	Random date in the specified min/max date range.
empty	Empty string.
random_time	Random time offset from the specified time.
replace(value)	Releases the tag with the specified value.

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