Constructor Detail

CmsExtractionResult

public CmsExtractionResult(java.util.Locale defaultLocale,
                           java.util.Map<java.util.Locale,java.util.LinkedHashMap<java.lang.String,java.lang.String>> multilingualContentItems,

Creates a new multilingual extraction result.

Parameters:

defaultLocale - the default (best fitting) locale of the result.

multilingualContentItems - the content items for the different locales

fieldMappings - special mappings to search fields with values extracted from the content

CmsExtractionResult

public CmsExtractionResult(java.lang.String content)

Creates a new extraction result without meta information and without additional fields.

Parameters:

content - the extracted content

CmsExtractionResult

public CmsExtractionResult(java.lang.String content,
                           java.util.LinkedHashMap<java.lang.String,java.lang.String> contentItems)

Creates a new unilingual extraction result.

Parameters:

content - the extracted content

contentItems - the individual extracted content items

CmsExtractionResult

public CmsExtractionResult(java.lang.String content,
                           java.util.LinkedHashMap<java.lang.String,java.lang.String> contentItems,
                           java.util.Map<java.lang.String,java.lang.String> fieldMappings)

Creates a new unilingual extraction result.

Parameters:

content - the extracted content

contentItems - the individual extracted content items

fieldMappings - extraction results that should directly be indexed

Method Detail

fromBytes

public static final CmsExtractionResult fromBytes(byte[] bytes)

Creates an extraction result from a serialized byte array.

Parameters:

bytes - the serialized version of the extraction result

Returns:

extraction result created from the serialized byte array

getBytes

public byte[] getBytes()

Description copied from interface: I_CmsExtractionResult

Returns this extraction result serialized as a byte array.

Specified by:

getBytes in interface I_CmsExtractionResult

Returns:

this extraction result serialized as a byte array

See Also:

I_CmsExtractionResult.getBytes()

getContent

public java.lang.String getContent()

Description copied from interface: I_CmsExtractionResult

Returns the extracted content of the best fitting locale combined as a String.

Specified by:

getContent in interface I_CmsExtractionResult

Returns:

the extracted content of the best fitting locale combined as a String

See Also:

I_CmsExtractionResult.getContent()

getContent

public java.lang.String getContent(java.util.Locale locale)

Description copied from interface: I_CmsExtractionResult

Returns the extracted content for the given locale combined as a String.

Specified by:

getContent in interface I_CmsExtractionResult

Parameters:

locale - the locale of the extracted content

Returns:

the extracted content for the given locale combined as a String

See Also:

I_CmsExtractionResult.getContent(java.util.Locale)

getContentItems

public java.util.LinkedHashMap<java.lang.String,java.lang.String> getContentItems()

Description copied from interface: I_CmsExtractionResult

Returns the extracted content for the best fitting locale as individual items.

The result Map contains all content items extracted by the extractor. The key is always a String, and contains the name of the item. The value is also a String and contains the extracted text.

The detailed form will depend on the resource type indexed:

• For a xmlpage, the key will be the element name, and the value will be the text of the element.
• For a xmlcontent, the key will be the xpath of the XML node, and the value will be the text of that XML node.
• In case the document contains meta information (for example PDF or MS Office documents), the meta information is stored with the name of the meta field as key and the content as value.
• For all other resource types, there will be only ony key I_CmsExtractionResult.ITEM_CONTENT, which will contain the value of the complete content.

The map has to be ordered to e.g., get the correct indexing order for search field mappings when a sequence of values is mapped to a multi-valued search field.

Specified by:

getContentItems in interface I_CmsExtractionResult

Returns:

the extracted content as individual items

See Also:

I_CmsExtractionResult.getContentItems()
