Constructor Details

TextMetaDataCollectionExtractingProcessor

public TextMetaDataCollectionExtractingProcessor(String... metaDataNodesXPathQueries)

Default constructor. Sets the metaDataNodesXPathQueries to the provided argument.

Method Details

process

public Item process(Context context,
 CachingOptions cachingOptions,
 Item item)
             throws ItemProcessingException

For every XPath query provided in metaDataNodesXPathQueries, a list of nodes is selected and for each one of these nodes its text value is extracted and added to a list that is later put in the item's properties.

Specified by:

process in interface ItemProcessor

Parameters:

context - the current context

cachingOptions - caching options in case you need access to items

item - the item to process

Returns:

the modified item or a new item.

Throws:

ItemProcessingException - if an error occurred while processing the item

equals

public boolean equals(Object o)

Returns true if the specified TextMetaDataCollectionExtractingProcessor's and this instance's metaDataNodesXPathQueries are equal.

Overrides:

equals in class Object

hashCode

public int hashCode()

Returns the hash code for this instance, which is basically hash code of the list of XPath queries. As with any other ItemProcessor, this method is defined because any processor which is passed in the method call of a ContentStoreService can be used as part of a key for caching.

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
