Document

Method similar to #writeBinary(Base64Variant,byte[],int,int) , but where input is provided through a stream, allowing for incremental writes without holding the whole input in memory.

Usage

From source file:com.google.api.server.spi.response.ServletResponseResultWriter.java

private static SimpleModule getWriteBlobAsBase64Module() {
    JsonSerializer<Blob> dateSerializer = new JsonSerializer<Blob>() {
        @Override/*from  w w  w  . j  a  v a  2s .co  m*/
        public void serialize(Blob value, JsonGenerator jgen, SerializerProvider provider) throws IOException {
            byte[] bytes = value.getBytes();
            jgen.writeBinary(bytes, 0, bytes.length);
        }
    };
    SimpleModule writeBlobAsBase64Module = new SimpleModule("writeBlobAsBase64Module",
            new Version(1, 0, 0, null, null, null));
    writeBlobAsBase64Module.addSerializer(Blob.class, dateSerializer);
    return writeBlobAsBase64Module;
