Interface FragmentInfo

  • All Superinterfaces:
    EntryInfo


    public interface FragmentInfo
    extends EntryInfo
    FragmentInfo extends the EntryInfo interface to add variables unique to externally cacheable pages.

    EntryInfo and FragmentInfo Objects are attached to each cache entry. IdGenerators and MetaDataGenerators use these interfaces to define the caching metadata for an entry.

    Typically a Id/MetaDataGenerator will get an entry's FragmentInfo object from the ServletCacheRequest, and use the object's set methods to configure that entry.

    The following is a summary of the caching metadata for a CacheEntry:

    • The template. (set internally by WebSphere)
    • The id. (set internally by WebSphere with the output of the IdGenerator.getId() method)
    • The priority.
    • The timeLimit and expirationTime options.
    • The dataIds option.
    • The external cache group to which this entry will be pushed (FragmentInfo)

      • getExternalCacheGroupId

        java.lang.String getExternalCacheGroupId()
        This gets the externalCacheGroupId variable.
        Returns:
        The externalCacheGroupId.
      • setExternalCacheGroupId

        void setExternalCacheGroupId(java.lang.String externalCacheGroupId)
        This sets the externalCacheGroupId variable.
        Parameters:
        externalCacheGroupId - The externalCacheGroupId.
      • wasExternalCacheGroupIdSet

        boolean wasExternalCacheGroupIdSet()
        This indicates whether the client set the external cache group id in this FragmentInfo.
        Returns:
        True implies it was set.
      • setStoreAttributes

        void setStoreAttributes(boolean b)
        This sets the store-attributes variable. If storeAttributes is set to false then the request attributes will not be saved with the servlet response. The default value is true.

        b - a boolean that indicates whether or not attributes should be saved.
      • getStoreAttributes

        boolean getStoreAttributes()
        This indicates whether or not request attributes are being saved with the servlet response.
        Returns:
        boolean true means that attributes will be saved
      • setStoreCookies

        void setStoreCookies(boolean b)
        This sets the store-cookies variable. If storeCookies is set to false then the cookies will not be saved with the servlet response. The default value is true.
        Parameters:

      • getStoreCookies

        boolean getStoreCookies()
        This indicates whether or not cookies are being saved with the servlet response.
        Returns:
        boolean true means that cookies will be saved
      • setConsumeSubfragments

        void setConsumeSubfragments(boolean b)
        This sets the consume-subfragments variable. If consumeSubfragments is set to true then the parent will consume child fragments in its cache entry. The default value is false.
        Parameters:
        b - a boolean that indicates whether or not the parent will consume-subfragments
      • getConsumeSubfragments

        boolean getConsumeSubfragments()
        This indicates whether or not the parent is consuming child fragments in its cache entry.
        Returns:
        boolean true means that the parent will consume child fragments
      • setIgnoreGetPost

        void setIgnoreGetPost(boolean b)
        This sets the ignore-get-post variable. If ignore-get-post is set to true then the requestType will automatically be appended to the cache-id
        Parameters:
        b - a boolean that indicates whether or not to append the requestType to the cache-id saved.
      • isIgnoreGetPost

        boolean isIgnoreGetPost()
        This indicates whether or not the requestType will automatically be appended to the cache-id
        Returns:
        boolean true means that the requestType will not be appended to the cache-id
