SDTStreamContainer ( )

Defines a Structured Data Type (SDT) stream container. A stream is an iterable collection of solace.SDTFields.

## Methods Detail Top

###
public void addField ( solace.SDTField | solace.SDTFieldType typeOrField, * value )

Appends a field to this stream.

Deprecated: If `typeOrField` is a solace.SDTField instance, it is appended to the stream. The preferred usage is to pass a solace.SDTFieldType, then the API will create a SDTField of this type using `value` and append this new SDTField to the stream.

#### Parameters

solace.SDTField | solace.SDTFieldType | typeOrField A SDTField instance or SDTFieldType.
* | value The value to wrap as an SDTField. (Optional)

#### Return Value

void |

#### Throws

| solace.OperationError if value does not match type
| solace.SDTUnsupportedValueError if value is not in range supported by the platform/runtime

###
public solace.SDTField getNext ( )

Returns the next field in the stream and advances the read pointer. If the end of the stream is reached, it returns undefined.

#### Return Value

solace.SDTField | The next field in the stream.

###
public Boolean hasNext ( )

Returns true if the stream has at least one more solace.SDTField at the current position.

#### Return Value

Boolean | true, if there is an available field at the read pointer; false, otherwise.

###
public void rewind ( )

Rewinds the read pointer to the beginning of the stream. Normally when hasNext returns false, a client application must call rewind() to reiterate over the stream's fields.

#### Return Value

void |

#### Throws

| solace.OperationError if the stream cannot be rewound.
