Method Detail

get

public static Value get(String value)

Get string or null value instance.

get

public static Value get(byte[] value)

Get byte array or null value instance.

get

public static Value get(byte[] value,
                        int offset,
                        int length)

Get byte segment or null value instance.

get

public static Value get(int value)

Get integer value instance.

get

public static Value get(long value)

Get long value instance.

get

public static Value get(Value[] value)

Get value array instance.

getAsBlob

public static Value getAsBlob(Object value)

Get blob or null value instance.

getAsList

public static Value getAsList(List<?> value)

Get list or null value instance. Supported by Aerospike 3 servers only.

getAsMap

public static Value getAsMap(Map<?,?> value)

Get map or null value instance. Supported by Aerospike 3 servers only.

getAsNull

public static Value getAsNull()

Throws:

AerospikeException

write

public abstract int write(byte[] buffer,
                          int offset)
                   throws AerospikeException

Serialize the value in the wire protocol.

Throws:

AerospikeException

pack

public abstract void pack(com.aerospike.client.util.Packer packer)
