Interface TemplateCachingHints

All Known Implementing Classes:

SimpleTemplateCachingHints

public interface TemplateCachingHints

TemplateCachingHints is used to indicate to the templating rendering mechanism whether the compiled template data should be cached and for how long.

Method Summary

long	getAccessTimeout() If the cached template data is not accessed in this time (in milliseconds) then it can be expired from the cache.
long	getLastModified() Returns the time the content of this TemplateDataSource was last modified.
long	getTimeToLive() The cached template data can reside in the cache for this many milliseconds, after which it can expire.

Method Detail

getAccessTimeout

long getAccessTimeout()

If the cached template data is not accessed in this time (in milliseconds) then it can be expired from the cache.

If this is -1, then the cached template data will not expire based on acess time.

Returns:

the time after which any cached entry will expire if it is not accessed, in milliseconds.

getLastModified

long getLastModified()

Returns the time the content of this TemplateDataSource was last modified.

The return value is used to decide whether to reparse a Source or not. Reparsing is done if the value returned here differs from the value returned at the last processing time. This may not return a 'real' time, it needs just to be comparable to itself; so some sort of version counter would be perfect as well.

Returns:

long a modification time or counter

getTimeToLive

long getTimeToLive()

The cached template data can reside in the cache for this many milliseconds, after which it can expire.

If this is -1, then the cached template data will live forever.

Returns:

the time this template data can reside in the cache in milliseconds.
