Constructor Detail

AbstractMapping

protected AbstractMapping()

Default constructor.

AbstractMapping

protected AbstractMapping(XtdbOMRSRepositoryConnector xtdbConnector)

Default constructor.

Parameters:

xtdbConnector - connectivity to XTDB

Method Detail

getKeyword

public static String getKeyword(String name)

Construct a string representation of a keyword.

Parameters:

name - of the keyword

Returns:

String representation of the form ':name'

getKeyword

public static String getKeyword(String namespace,
                                String name)

Construct a string representation of a keyword.

Parameters:

namespace - of the keyword (optional)

name - of the keyword

Returns:

String representation of the form ':namespace/name'

getEmbeddedSerializedForm

protected static clojure.lang.IPersistentMap getEmbeddedSerializedForm(XtdbOMRSRepositoryConnector xtdbConnector,
                                                                       String type,
                                                                       String property,

Retrieve an embedded JSON-serialized form of a given object. This will prevent the object from being searchable, but provides an efficient means to store structured information.

Parameters:

xtdbConnector - connectivity to the repository

type - name of the type into which the value is being serialized

property - name of the property for which the value is being serialized

value - to JSON-serialize

Returns:

IPersistentMap giving the embedded serialized form

getEmbeddedSerializedForm

protected static clojure.lang.IPersistentMap getEmbeddedSerializedForm(Object value)
                                                                throws IOException

Retrieve an embedded JSON-serialized form of a given object. This will prevent the object from being searchable, but provides an efficient means to store structured information.

Parameters:

value - to JSON-serialize

Returns:

IPersistentMap giving the embedded serialized form

Throws:

IOException - on any issue serializing the value

getDeserializedValue

protected static <T> T getDeserializedValue(XtdbOMRSRepositoryConnector xtdbConnector,
                                            String type,
                                            String property,
                                            clojure.lang.IPersistentMap embedded,
                                            com.fasterxml.jackson.databind.JavaType javaType)

Retrieve the deserialized value given an embedded form. This will prevent the object from being searchable, but provides an efficient means to retrieve structured information.

Type Parameters:

T - type of value to deserialize

Parameters:

xtdbConnector - connectivity to the repository

type - name of the type from which the value is being deserialized

property - name of the property from which the value is being deserialized

embedded - value to JSON-deserialize

javaType - the type of value to deserialize

Returns:

the deserialized value

getDeserializedValue

protected static <T> T getDeserializedValue(clojure.lang.IPersistentMap embedded,
                                            com.fasterxml.jackson.databind.JavaType javaType)
                                     throws IOException

Retrieve the deserialized value given an embedded form. This will prevent the object from being searchable, but provides an efficient means to retrieve structured information.
