Class BytesMarshaller<T>

java.lang.Object

net.openhft.chronicle.bytes.BytesMarshaller<T>

Type Parameters:

T - type being marshalled

public class BytesMarshaller<T>
extends Object

Reflection-based marshaller for simple objects. It inspects the fields of a class and serialises/deserialises them sequentially using FieldAccess helpers. This approach is generic but slower than hand-written marshalling.

BYTES_MARSHALLER_CL

public static final net.openhft.chronicle.core.util.ClassLocal<BytesMarshaller> BYTES_MARSHALLER_CL

Provides a ClassLocal instance for holding a unique BytesMarshaller for each class.

Constructor Detail

BytesMarshaller

public BytesMarshaller(@NotNull
                       @NotNull Class<T> tClass)

Constructs a BytesMarshaller for the specified class.

Parameters:

tClass - the class for which the BytesMarshaller is to be created.

Method Detail

getAllField

public static void getAllField(@NotNull
                               @NotNull Class<?> clazz,
                               @NotNull
                               @NotNull Map<String,Field> map)

Extracts all fields from the specified class and its superclasses and stores them in the provided map. Only non-static and non-transient fields are considered.

Parameters:

clazz - the class from which to extract fields.

map - the map in which to store the fields.

readMarshallable

public void readMarshallable(ReadBytesMarshallable t,
                             BytesIn<?> in)
                      throws net.openhft.chronicle.core.io.InvalidMarshallableException

Populates t by reading each field from in using reflection.

Throws:

net.openhft.chronicle.core.io.InvalidMarshallableException

writeMarshallable

public void writeMarshallable(WriteBytesMarshallable t,
                              BytesOut<?> out)
                       throws IllegalArgumentException,
                              net.openhft.chronicle.core.io.ClosedIllegalStateException,

                              BufferUnderflowException,
                              ArithmeticException,
                              net.openhft.chronicle.core.io.InvalidMarshallableException,
                              net.openhft.chronicle.core.io.ThreadingIllegalStateException
