Class EncryptionContext

java.lang.Object

com.amazonaws.services.dynamodbv2.datamodeling.encryption.EncryptionContext

public final class EncryptionContext
extends java.lang.Object

This class serves to provide additional useful data to EncryptionMaterialsProviders so they can more intelligently select the proper EncryptionMaterials or DecryptionMaterials for use. Any of the methods are permitted to return null.

For the simplest cases, all a developer needs to provide in the context are:

• TableName
• HashKeyName
• RangeKeyName (if present)

This class is immutable.
