Method Details

translateToAerospike

public Object translateToAerospike(Object obj)

Translate a Java object to an Aerospike format object. Note that this could potentially have performance issues as the type information of the passed object must be determined on every call.

Parameters:

obj - A given Java object.

Returns:

An Aerospike format object.

translateFromAerospike

public <T> T translateFromAerospike(@NotNull
 @NotNull Object obj,
 @NotNull
 @NotNull Class<T> expectedClazz)

Translate an Aerospike object to a Java object. Note that this could potentially have performance issues as the type information of the passed object must be determined on every call.

Parameters:

obj - A given Java object.

Returns:

An Aerospike format object.

convertToObject

public <T> T convertToObject(Class<T> clazz,
 com.aerospike.client.Key key,
 com.aerospike.client.Record record)

Given a record loaded from Aerospike and a class type, attempt to convert the record to an instance of the passed class.

Parameters:

clazz - The class type to convert the Aerospike record to.

record - The Aerospike record to convert.

Returns:

A virtual list.

convertToObject

public <T> T convertToObject(Class<T> clazz,
 com.aerospike.client.Key key,
 com.aerospike.client.Record record,
 ClassCacheEntry<T> entry)

Given a record loaded from Aerospike and a class type, attempt to convert the record to an instance of the passed class.

Parameters:

clazz - The class type to convert the Aerospike record to.

record - The Aerospike record to convert.

entry - The entry that holds information on how to store the provided class.

Returns:

A virtual list.

convertToObject

public <T> T convertToObject(Class<T> clazz,
 com.aerospike.client.Key key,
 com.aerospike.client.Record record,
 ClassCacheEntry<T> entry,
 boolean resolveDependencies)

This method should not be used, it is public only to allow mappers to see it.

convertToObject

public <T> T convertToObject(Class<T> clazz,
 List<Object> record)

Given a list of records loaded from Aerospike and a class type, attempt to convert the records to an instance of the passed class.

Parameters:

clazz - The class type to convert the Aerospike record to.

record - The Aerospike records to convert.

Returns:

A virtual list.

Throws:

com.aerospike.client.AerospikeException - an AerospikeException will be thrown in case of an encountering a ReflectiveOperationException.

convertToObject

public <T> T convertToObject(Class<T> clazz,
 List<Object> record,
 boolean resolveDependencies)

This method should not be used, it is public only to allow mappers to see it.

convertToObject

public <T> T convertToObject(Class<T> clazz,
 Map<String,Object> record)

Given a map of records loaded from Aerospike and a class type, attempt to convert the records to an instance of the passed class.

Parameters:

clazz - The class type to convert the Aerospike record to.

record - The Aerospike records to convert.

Returns:

A virtual list.

Throws:

com.aerospike.client.AerospikeException - an AerospikeException will be thrown in case of an encountering a ReflectiveOperationException.

convertToList

public <T> List<Object> convertToList(@NotNull
 T instance)

Given an instance of a class (of any type), convert its properties to a list

Parameters:

instance - The instance of a class (of any type).

Returns:

a List of the properties of the given instance.

convertToMap

public <T> Map<String,Object> convertToMap(@NotNull
 T instance)

Given an instance of a class (of any type), convert its properties to a map, properties names will use as the key and properties values will be the values.

Parameters:

instance - The instance of a class (of any type).

Returns:

the properties Map of the given instance.

resolveDependencies

public void resolveDependencies(ClassCacheEntry<?> parentEntity)

If an object refers to other objects (eg A has a list of B via references), then reading the object will populate the ids. If configured to do so, these objects can be loaded via a batch load and populated back into the references which contain them. This method performs this batch load, translating the records to objects and mapping them back to the references.

These loaded child objects can themselves have other references to other objects, so we iterate through this until the list of deferred objects is empty. The deferred objects are stored in a

ThreadLocalData
 list, so are thread safe

Parameters:

parentEntity - - the ClassCacheEntry of the parent entity. This is used to get the batch policy to use.
