Specified by:

getBuilder in interface FieldSetMarshaller<EnumSet<E extends Enum<E>>,EnumSetBuilder<E extends Enum<E>>>

Returns:

a builder.

getFields

public int getFields()

Description copied from interface: FieldSetMarshaller

Returns the number of fields written by this marshaller.

Specified by:

getFields in interface FieldSetMarshaller<EnumSet<E extends Enum<E>>,EnumSetBuilder<E extends Enum<E>>>

Returns:

a positive number

readField

public EnumSetBuilder<E> readField(ProtoStreamReader reader,
                                   int index,
                                   EnumSetBuilder<E> builder)
                            throws IOException

Description copied from interface: FieldSetMarshaller

Reads a single field from the specified reader at the specified index.

Specified by:

readField in interface FieldSetMarshaller<EnumSet<E extends Enum<E>>,EnumSetBuilder<E extends Enum<E>>>

Parameters:

reader - a ProtoStream reader

index - the field index

builder - the builder to be populated with the read field

Returns:

the builder containing the read field

Throws:

IOException - if the field could not be read

writeFields

public void writeFields(ProtoStreamWriter writer,
                        int startIndex,
                        EnumSet<E> set)
                 throws IOException

Description copied from interface: FieldSetMarshaller

Writes the set of fields from the specified object to the specified writer beginning at the specified index.

Specified by:

writeFields in interface FieldSetMarshaller<EnumSet<E extends Enum<E>>,EnumSetBuilder<E extends Enum<E>>>

Parameters:

writer - a ProtoStream writer

startIndex - the start index for the embedded fields

set - the value to be written

Throws:

IOException - if the value could not be written
