PROTOSTREAM_PACKAGE

private static final String PROTOSTREAM_PACKAGE

ADAPTER_FIELD_NAME

protected static final String ADAPTER_FIELD_NAME

See Also:

• Constant Field Values

typeFactory

private final XTypeFactory typeFactory

noDefaults

private final boolean noDefaults

Do nullable fields that do not have a user defined default value get a default type specific value if missing instead of just null? This is currently implemented just for arrays/collections. TODO Maybe numbers should also receive a 0 default value and booleans a false value. But what about strings? Empty string does not sound like a good fit. See the spec we do not fully implement here: Optional

private String generateMapFieldReadMethod(ProtoFieldMetadata fieldMetadata,
 IndentWriter iw,
 boolean readNext)

makeFieldTag

private static String makeFieldTag(int fieldNumber,
 WireType wireType)

toJavaLiteral

private String toJavaLiteral(Object value,
 XClass javaType)

Converts a given value instance to a Java language literal of type javaType. The input value is expected to conform to the given type (no checks are performed).

genSetField

private void genSetField(IndentWriter iw,
 ProtoFieldMetadata fieldMetadata,
 Map<String,Integer> trackedFields,
 ProtoMessageTypeMetadata messageTypeMetadata)

generateWriteMethodBody

convert

private String convert(String v,
 ProtoFieldMetadata fieldMetadata)

Cast the given value if necessary. This is usually needed for the types that we are forced to represent as 32-bit integers because of Protobuf's lack of support for integral types of 8 and 16 bits.

box

private XClass box(XClass clazz)

Return the corresponding 'boxed' Class given a Class, or null if no type change is required.

box

private String box(String v,
 XClass clazz)

Boxes a given value. The Class parameter can be null to indicate that no boxing should actually be performed.

unbox

private String unbox(String v,
 XClass clazz)

createGetPropExpr

private String createGetPropExpr(ProtoMessageTypeMetadata messageTypeMetadata,
 ProtoFieldMetadata fieldMetadata,
 String obj)

createSetPropExpr

 String obj,
 String value)

public abstract void generateMarshaller(SerializationContext serCtx,
 ProtoTypeMetadata ptm)
                                 throws Exception

Throws:
