public abstract class AbstractCacheManager extends Object implements ICacheManager
Common abstract class for ICacheManager
implementations, useful
for taking care of the lazy initialization of cache objects when their
corresponding getXCache() methods are called.
Note a class with this name existed since 2.0.0, but it was completely reimplemented in Thymeleaf 3.0

Clears all the caches managed by this cache manager instance.

public final ICache<TemplateCacheKey,TemplateModel> getTemplateCache()
ICacheManager
Returns the cache of parsed templates. Keys are the template names,
as specified at the TemplateEngine.process(String, org.thymeleaf.context.IContext)
method.

public final ICache<ExpressionCacheKey,Object> getExpressionCache()
ICacheManager
Returns the cache of expression evaluation artifacts.
This cache is meant to store artifacts of diverse nature needed along the process of parsing and executing expressions in the several languages available: Standard expressions, OGNL expressions, Spring EL expressions...
Parsing these expressions usually results in some kind of syntax tree object that represents the expression, and this is what this cache usually stores.
Keys are the expressions themselves (their String representation), along with a type that is normally used for identifying the nature of the object being cached (for example {"ognl","person.name"}).

public <K,V> ICache<K,V> getSpecificCache(String name)
ICacheManager
Returns a specific (non-default) cache, by its name.
User-defined dialects might make use of additional caches (besides template, and expression) defined at custom-made implementations of this interface, and they should use this method to retrieve them by their name.
Note the default StandardCacheManager
will return null for every
call to this method, as it should be custom implementations of this interface (or
extensions of AbstractCacheManager
or extensions StandardCacheManager
)
who implement these specific caches and offer their names through the
ICacheManager.getAllSpecificCacheNames()
method.

ICacheManager
Returns a list with the names of all the specific caches managed by this implementation.
Might return null if no specific caches are managed.

public void clearAllCaches()
ICacheManager
Clears all the caches managed by this cache manager instance.
This method is mainly intended for use from external tools that might need to clean all caches completely, without having to worry about implementation details.
