org.craftercms.core.processors.impl.TextMetaDataExtractingProcessor

All Implemented Interfaces:

ItemProcessor

public class TextMetaDataExtractingProcessor
extends Object
implements ItemProcessor

ItemProcessor that extracts single text values from descriptor XPath-selected nodes and sets them as the properties of the item. All XPath queries should only return single nodes. For extracting values for a list of nodes use TextMetaDataCollectionExtractingProcessor.

Field Detail

metaDataNodesXPathQueries

protected String[] metaDataNodesXPathQueries

Array of XPath queries for the nodes whose values should be extracted.

Constructor Detail

TextMetaDataExtractingProcessor

public TextMetaDataExtractingProcessor(String... metaDataNodesXPathQueries)

Default constructor. Sets the metaDataNodesXPathQueries to the provided argument.

Method Detail

process

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

For every XPath query provided in metaDataNodesXPathQueries, a single node is selected and its text value is extracted and 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.

equals

public boolean equals(Object o)

Returns true if the specified TextMetaDataExtractingProcessor'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
