Get(handle, string[, integer])

説明

The Get function returns a string with information about a specified property of the object, for instance, the object's name, class, or path.

引数

• handle:
  The function takes a handle of the type "light_userdata" as an argument.
  It can be omitted when using the colon notation on an object.
  

  The Colon Notation is a way to omit the handle as the first argument when using the Object functions.

  This is the general syntax with the colon notation: object:function()

  This is the general syntax with standard handle notation: object.function(object)

• string:
  The string must be the name of a valid property for the object.
  
• integer (オプション):
  A valid role integer can be supplied. This will make the returned value a text string.
  

戻り値

• string:
  The function returns the value of the property. If the property is a boolean, then the return is "0" or "1" unless a role is defined (see optional integer argument above). When the role is supplied, a boolean is returned as "No" or "Yes".
  

例

This example prints information about the "Tracking" property of the selected sequence.

return function ()
    -- SelectedSequence() creates a handle to the selected sequence.
    local selectedSequence = SelectedSequence()
    -- Check if there is a selected sequence. If not, then exit the function.
    if selectedSequence == nil then
        ErrPrintf("The selected sequence could not be found.")
        return
    end
    -- Set a variable with the property name.
    local propertyName = "Tracking"
    -- Get the value of the property. 
    local propertyValue = selectedSequence:Get(propertyName)
    local propertyValueString = selectedSequence:Get(propertyName, Enums.Roles.Edit)
    -- Return some feedback.
    if propertyValue ~= nil then
        Printf("The selected sequence's property " .. propertyName.. " has the value '" .. propertyValue .. "' and a string value of '" .. propertyValueString .. "'.")
    else
        ErrPrintf("The property could not be found.")
    end
end
