• the extracted property is not null
• there is no target key for the property

Method Detail

values

public static final MetadataExtracter.OverwritePolicy[] values()

applyProperties

public java.util.Map applyProperties(java.util.Map extractedProperties,
                                     java.util.Map targetProperties)

Apply the overwrite policy for the extracted properties.
