Methods

Name Return Value Summary
GetRawEnumerator() IEnumerator<KeyValuePair<string, object>>
Enumerates raw key-value pairs (I.e., the values have not been expanded similar to TryGetRaw(string, object)).
TryGetRaw(string, object) bool
Tries to get the raw value for the specified key. This method will not materialize IMetadataValue values or process script strings the way the TryGetValue<TValue>(IMetadata, string, TValue) extension and other get methods will. A System.Collections.Generic.KeyNotFoundException will be thrown for missing keys.

Extension Methods

Name Value Summary

ContainsAnyKeys<string, object>(IEnumerable<string>) bool
Determines whether the dictionary contains all the specified keys.

Determines whether the dictionary contains all the specified keys.
ContainsKeys<string, object>(string[]) bool

Gets a new filtered IMetadata containing only the specified keys and their values. If a key is not present in the current metadata, it will be ignored and will not be copied to the new metadata object.
Get(string, object) object
Gets the value for the specified key. This method never throws an exception. It will return the specified default value or null if the key is not found or is null.
Get<T>(string, T) T
Gets the value for the specified key. This method never throws an exception. It will return the specified default value if the key is not found or is null.
Get<T>(string) T
Gets the value for the specified key converted to the specified type. This method never throws an exception. It will return default(T) if the key is not found, is null, or the value cannot be converted to T.

Gets the value for the specified key converted to a bool. This method never throws an exception. It will return the specified default value if the key is not found.
