Constructor Detail

### Blob

    public Blob(byte[] bytes)

  Construct a new `Blob` with the specified bytes. Since `Blobs` can be quite large we do not perform a defensive copy of the provided byte array. It is the programmer's responsibility to avoid making changes to this array once the `Blob` has been constructed.

Method Detail

### getBytes

    public byte[] getBytes()

  Return the bytes stored in this `Blob`.

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `java.lang.Object`

### equals

    public boolean equals(java.lang.Object object)

  Two `Blob` objects are considered equal if their contained bytes match exactly.

  Overrides:
    `equals` in class `java.lang.Object`

### toString

    public java.lang.String toString()

  Simply prints the number of bytes contained in this `Blob`.

  Overrides:
    `toString` in class `java.lang.Object`
