Methods summary
`public`	# `evaluateDependency( )` Evaluates the dependency by generating and saving the data related with dependency. This method is invoked by cache before writing data into it. Evaluates the dependency by generating and saving the data related with dependency. This method is invoked by cache before writing data into it. Implementation of `ICacheDependency::evaluateDependency()`
`public boolean`	# `getHasChanged( )` Returns `boolean` whether the dependency has changed. Implementation of `ICacheDependency::getHasChanged()`
`public mixed`	# `getDependentData( )` Returns `mixed` the data used to determine if dependency has been changed. This data is available after `CCacheDependency::evaluateDependency()` is called.
`public static`	# `resetReusableData( )` Resets cached data for reusable dependencies. Resets cached data for reusable dependencies. Since 1.1.14
`protected mixed`	# `generateDependentData( )` Generates the data needed to determine if dependency has been changed. Derived classes should override this method to generate actual dependent data. Generates the data needed to determine if dependency has been changed. Derived classes should override this method to generate actual dependent data. Returns `mixed` the data needed to determine if dependency has been changed.

Properties summary
`public boolean`	`$reuseDependentData`	`false`	# Whether this dependency is reusable or not. If set to true, dependent data for this cache dependency will only be generated once per request. You can then use the same cache dependency for multiple separate cache calls on the same page without the overhead of re-evaluating the dependency each time. Defaults to false; Whether this dependency is reusable or not. If set to true, dependent data for this cache dependency will only be generated once per request. You can then use the same cache dependency for multiple separate cache calls on the same page without the overhead of re-evaluating the dependency each time. Defaults to false; Since 1.1.11
