High-performance serialization and deserialization protostuff usage

1. Quoting the jar package:

pom.xml :

<!-- protostuff -->

        <dependency>

            <groupId>com.dyuproject.protostuff</groupId>

            <artifactId>protostuff-core</artifactId>

            <version>1.0.7</version>

            <optional>true</optional>

            <scope>provided</scope>

        </dependency>

        <dependency>

            <groupId>com.dyuproject.protostuff</groupId>

            <artifactId>protostuff-runtime</artifactId>

            <version>1.0.7</version>

            <optional>true</optional>

            <scope>provided</scope>

 

        </dependency>

 

Serialization example:

 

public List<byte[]> serializeProtoStuffProductsList(List<Products> pList) {

        if(pList == null  ||  pList.size() <= 0) {

            return null;

        }

        long start = System.currentTimeMillis() ;

        List<byte[]> bytes = new ArrayList<byte[]>();

        Schema<Products> schema = RuntimeSchema.getSchema(Products.class);

        LinkedBuffer buffer = LinkedBuffer.allocate(4096);

        byte[] protostuff = null;

        for(Products p : pList) {

            try {

                protostuff = ProtostuffIOUtil.toByteArray(p, schema, buffer);

                bytes.add(protostuff);

            } finally {

                buffer.clear();

            }

        }

        long end = System.currentTimeMillis() ;

        this.userTime = end - start;

        return bytes;

 

    }

 

Deserialization example:

public List<Products> deserializeProtoStuffDataListToProductsList(

            List<byte[]> bytesList) {

        if(bytesList == null || bytesList.size() <= 0) {

            return null;

        }

        long start = System.currentTimeMillis() ;

        Schema<Products> schema = RuntimeSchema.getSchema(Products.class);

        List<Products> list = new ArrayList<Products>();

        for(byte[] bs : bytesList) {

            Products product = new Products();

            ProtostuffIOUtil.mergeFrom(bs, product, schema);

            list.add(product);

        }

        long end = System.currentTimeMillis() ;

        this.userTime = end - start;

        return list;

 

    }
