Usage

• [ConfigurationData(Fallback = True)]

Constructors

ConfigurationAttribute()

Default, empty constructor. All properties must be added in a named fashion to ensure long-term API consistency.

public ConfigurationAttribute()

Properties

CacheRelevant

Determine if the configuration is cache relevant. It usually is. But anything that doesn't change the output should be set to false, to avoid cache bloat.

public bool CacheRelevant { get; set; }

Property Value

bool

Fallback

The fallback value to use, if code/configuration don't give this another value. Note that internally it will be converted to a string, because Tokens work that way.

public object Fallback { get; set; }

Property Value

object

Field

Optional field name to use, if you must override the default. The default is that it uses the same name as the property, and this is highly recommended. You should only set the field, if you are renaming the property and it must still get data from old configurations.

public string Field { get; set; }

Property Value

string

Token

The Token is the most complicated way to create a field mask. You should normally not use this It must have the full syntax inside [...]. Examples:

• [Source:Key]
• [Source:Key|format]
• [Source:Key||Fallback]
• [Source:Key|format|Fallback]
• [Source:Key||[SubSource:SubKey||FinalFallback]]
• etc.

public string Token { get; set; }

Property Value

string
