Method Detail

getDBDocument

public static DBDocumentImpl getDBDocument(org.ojai.Document r)

encode

public static SerializedFamilyInfo[] encode(org.ojai.Document document,
                            Map<org.ojai.FieldPath,Integer> jsonPathMap,
                            boolean isBulkLoad,
                            boolean useCached)

encode

public static SerializedFamilyInfo[] encode(org.ojai.Document document,
                            Map<org.ojai.FieldPath,Integer> jsonPathMap)

encode

public static ByteBuffer encode(org.ojai.Document document)

Encodes an input OJAI document into a byte array in rowcol format. Currently it assumes that there is only one column family but in the future if we add support for multiple column families, then this function would also take a mapping from column name to column family name and return an array of Byte buffer, one for each column family.

Parameters:

document - OJAI document

Returns:

an array of Byte buffer

decodeInternal

public static void decodeInternal(Map<Integer,ByteBuffer> map,
                  Map<org.ojai.FieldPath,Integer> jsonPathMap,
                  Map<Integer,String> idToCFNameMap,
                  boolean insertionOrder,
                  boolean decodeTimestamp,
                  boolean preserveDeleteFlags,
                  DBDocumentImpl outDoc)

decode

public static DBDocumentImpl decode(Map<Integer,ByteBuffer> map,
                    Map<org.ojai.FieldPath,Integer> jsonPathMap,
                    Map<Integer,String> idToCFNameMap)

decode

public static DBDocumentImpl decode(Map<Integer,ByteBuffer> map,
                    Map<org.ojai.FieldPath,Integer> jsonPathMap,
                    Map<Integer,String> idToCFNameMap,
                    ByteBuffer rowKey,
                    boolean excludeId,
                    boolean cacheEncoded,
                    boolean insertionOrder,
                    boolean decodeTimestamp,
                    boolean preserveDeleteFlags)

decode

public static org.ojai.Document decode(ByteBuffer input)

decode

public static org.ojai.Document decode(ByteBuffer input,
                       ByteBuffer rowKey,
                       boolean excludeId,
                       boolean decodeTimestamp,
                       boolean preserveDeleteFlags)

Decodes a serialized byte buffer and returns a document. If the passed rowkey is not null, then it is included as the "_id" key at the root level with type binary.

This method will always decode the document.

decodeMutation

public static org.ojai.store.DocumentMutation decodeMutation(ByteBuffer input,
                                             boolean needsRead)
