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

### equals

    public boolean equals(java.lang.Object obj)

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

### toString

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

### getName

    public java.lang.String getName()

  Returns the name of this task. This may have been generated by a call to `Queue.add()` if the name was not otherwise specified.

### getQueueName

    public java.lang.String getQueueName()

  Returns the name of the queue that this task was submitted into.

### getEtaMillis

    public long getEtaMillis()

  Returns a time comparable to `System.currentTimeMillis()` when this task is scheduled for execution.

### getRetryCount

    public java.lang.Integer getRetryCount()

  Returns number of leases that had been performed on this task. Can return `null`.

### getPayload

    public byte[] getPayload()

  Returns binary payload data of this task. Can return `null`.

### getTag

    public java.lang.String getTag()
                            throws java.io.UnsupportedEncodingException

  Returns tag of this task. Can return `null`.

  Throws:
    `java.io.UnsupportedEncodingException`

### getTagAsBytes

    public byte[] getTagAsBytes()

  Returns tag of this task. Can return `null`.

### extractParams

    public java.util.List<java.util.Map.Entry<java.lang.String,java.lang.String>> extractParams()
                                                                                         throws java.io.UnsupportedEncodingException,
                                                                                                java.lang.UnsupportedOperationException

  Attempts to decode the `payload` byte array in our `options` into a list of Map.Entry<String, String>.

  Throws:
    `java.io.UnsupportedEncodingException` - if the payload cannot be decoded as a `application/x-www-form-urlencoded` string.
    `java.lang.UnsupportedOperationException` - if the `options` has no payload or the payload bytes could not be interpreted as application/x-www-form-urlencoded key-value pairs.
