Class BinaryData

  • public final class BinaryData
extends Object
    BinaryData is a convenient data interchange class for use throughout the Azure SDK for Java. Put simply, BinaryData enables developers to bring data in from external sources, and read it back from Azure services, in formats that appeal to them. This leaves BinaryData, and the Azure SDK for Java, the task of converting this data into appropriate formats to be transferred to and from these external services. This enables developers to focus on their business logic, and enables the Azure SDK for Java to optimize operations for best performance.

    BinaryData in its simplest form can be thought of as a container for content. Often this content is already in-memory as a String, byte array, or an Object that can be serialized into a String or byte[]. When the BinaryData is about to be sent to an Azure Service, this in-memory content is copied into the network request and sent to the service.

    In more performance critical scenarios, where copying data into memory results in increased memory pressure, it is possible to create a BinaryData instance from a stream of data. From this, BinaryData can be connected directly to the outgoing network connection so that the stream is read directly to the network, without needing to first be read into memory on the system. Similarly, it is possible to read a stream of data from a BinaryData returned from an Azure Service without it first being read into memory. In many situations, these streaming operations can drastically reduce the memory pressure in applications, and so it is encouraged that all developers very carefully consider their ability to use the most appropriate API in BinaryData whenever they encounter an client library that makes use of BinaryData.

    Refer to the documentation of each method in the BinaryData class to better understand its performance characteristics, and refer to the samples below to understand the common usage scenarios of this class.

    BinaryData can be created from an InputStream, a Flux of ByteBuffer, a String, an Object, a file, or a byte array.

    A note on data mutability

    BinaryData does not copy data on construction. BinaryData keeps a reference to the source content and is accessed when a read request is made. So, any modifications to the underlying source before the content is read can result in undefined behavior.

    To create an instance of BinaryData, use the various static factory methods available. They all start with 'from' prefix, for example fromBytes(byte[]).

    Create an instance from a byte array

     final byte[] data = "Some Data".getBytes(StandardCharsets.UTF_8);
 BinaryData binaryData = BinaryData.fromBytes(data);
 System.out.println(new String(binaryData.toBytes(), StandardCharsets.UTF_8));

    Create an instance from a String

     final String data = "Some Data";
 // Following will use default character set as StandardCharsets.UTF_8
 BinaryData binaryData = BinaryData.fromString(data);
 System.out.println(binaryData.toString());

    Create an instance from an InputStream

     final ByteArrayInputStream inputStream = new ByteArrayInputStream("Some Data".getBytes(StandardCharsets.UTF_8));
 BinaryData binaryData = BinaryData.fromStream(inputStream);
 System.out.println(binaryData.toString());

    Create an instance from an Object

     class Person {
     @JsonProperty
     private String name;

     @JsonSetter
     public Person setName(String name) {
         this.name = name;
         return this;
     }

     @JsonGetter
     public String getName() {
         return name;
     }
 }
 final Person data = new Person().setName("John");

 // Provide your custom serializer or use Azure provided serializers.
 // https://mvnrepository.com/artifact/com.azure/azure-core-serializer-json-jackson or
 // https://mvnrepository.com/artifact/com.azure/azure-core-serializer-json-gson
 BinaryData binaryData = BinaryData.fromObject(data);

 System.out.println(binaryData.toString());

    Create an instance from Flux<ByteBuffer>

     final byte[] data = "Some Data".getBytes(StandardCharsets.UTF_8);
 final Flux<ByteBuffer> dataFlux = Flux.just(ByteBuffer.wrap(data));

 Mono<BinaryData> binaryDataMono = BinaryData.fromFlux(dataFlux);

 Disposable subscriber = binaryDataMono
     .map(binaryData -> {
         System.out.println(binaryData.toString());
         return true;
     })
     .subscribe();

 // So that your program wait for above subscribe to complete.
 TimeUnit.SECONDS.sleep(5);
 subscriber.dispose();

    Create an instance from a file

     BinaryData binaryData = BinaryData.fromFile(new File("path/to/file").toPath());
 System.out.println(new String(binaryData.toBytes(), StandardCharsets.UTF_8));

      • fromFile

        public static BinaryData fromFile​(Path file)
        Creates a BinaryData that uses the content of the file at Path as its data. This method checks for the existence of the file at the time of creating an instance of BinaryData. The file, however, is not read until there is an attempt to read the contents of the returned BinaryData instance.

        Create an instance from a file

         BinaryData binaryData = BinaryData.fromFile(new File("path/to/file").toPath());
 System.out.println(new String(binaryData.toBytes(), StandardCharsets.UTF_8));
        Parameters:
        file - The Path that will be the BinaryData data.
        Returns:
        A new BinaryData.
        Throws:
        NullPointerException - If file is null.

      • fromFile

        public static BinaryData fromFile​(Path file,
                                  int chunkSize)
        Creates a BinaryData that uses the content of the file at file as its data. This method checks for the existence of the file at the time of creating an instance of BinaryData. The file, however, is not read until there is an attempt to read the contents of the returned BinaryData instance.

        Create an instance from a file

         BinaryData binaryData = BinaryData.fromFile(new File("path/to/file").toPath(), 8092);
 System.out.println(new String(binaryData.toBytes(), StandardCharsets.UTF_8));
        Parameters:
        file - The Path that will be the BinaryData data.
        chunkSize - The requested size for each read of the path.
        Returns:
        A new BinaryData.
        Throws:
        NullPointerException - If file is null.
        IllegalArgumentException - If offset or length are negative or offset plus length is greater than the file size or chunkSize is less than or equal to 0.
        UncheckedIOException - if the file does not exist.

      • toBytes

        public byte[] toBytes()
        Returns a byte array representation of this BinaryData. This method returns a reference to the underlying byte array. Modifying the contents of the returned byte array will also change the content of this BinaryData instance. If the content source of this BinaryData instance is a file, an Inputstream or a Flux<ByteBuffer> the source is not modified. To safely update the byte array, it is recommended to make a copy of the contents first.
        Returns:
        A byte array representing this BinaryData.

      • toString

        public String toString()
        Returns a String representation of this BinaryData by converting its data using the UTF-8 character set. A new instance of String is created each time this method is called.
        Overrides:
        toString in class Object
        Returns:
        A String representing this BinaryData.

      • toObject

        public <T> T toObject​(Class<T> clazz)
        Returns an Object representation of this BinaryData by deserializing its data using the default JsonSerializer. Each time this method is called, the content is deserialized and a new instance of type T is returned. So, calling this method repeatedly to convert the underlying data source into the same type is not recommended.

        The type, represented by Class, should be a non-generic class, for generic classes use toObject(TypeReference).

        Note: This method first looks for a JsonSerializerProvider implementation on the classpath. If no implementation is found, a default Jackson-based implementation will be used to deserialize the object.

      • toObject

        public <T> T toObject​(TypeReference<T> typeReference)
        Returns an Object representation of this BinaryData by deserializing its data using the default JsonSerializer. Each time this method is called, the content is deserialized and a new instance of type T is returned. So, calling this method repeatedly to convert the underlying data source into the same type is not recommended.

        The type, represented by TypeReference, can either be a generic or non-generic type. If the type is generic create a sub-type of TypeReference, if the type is non-generic use TypeReference.createInstance(Class).

        Note: This method first looks for a JsonSerializerProvider implementation on the classpath. If no implementation is found, a default Jackson-based implementation will be used to deserialize the object.

      • toObject

        public <T> T toObject​(TypeReference<T> typeReference,
                      ObjectSerializer serializer)
        Returns an Object representation of this BinaryData by deserializing its data using the passed ObjectSerializer. Each time this method is called, the content is deserialized and a new instance of type T is returned. So, calling this method repeatedly to convert the underlying data source into the same type is not recommended.

        The type, represented by TypeReference, can either be a generic or non-generic type. If the type is generic create a sub-type of TypeReference, if the type is non-generic use TypeReference.createInstance(Class).

        The passed ObjectSerializer can either be one of the implementations offered by the Azure SDKs or your own implementation.

      • toObjectAsync

        public <T> Mono<T> toObjectAsync​(Class<T> clazz)
        Returns an Object representation of this BinaryData by deserializing its data using the default JsonSerializer. Each time this method is called, the content is deserialized and a new instance of type T is returned. So, calling this method repeatedly to convert the underlying data source into the same type is not recommended.

        The type, represented by Class, should be a non-generic class, for generic classes use toObject(TypeReference).

        Note: This method first looks for a JsonSerializerProvider implementation on the classpath. If no implementation is found, a default Jackson-based implementation will be used to deserialize the object.
