OutputTuple (IBM Streams Java Operator API)

All Superinterfaces:

Tuple
```
public interface OutputTuple
extends Tuple
```
A mutable object that represents a tuple that can be submitted on an output port using the interface StreamingOutput.
Once an OutputTuple is submitted, any modification to it will not modify the version of the tuple seen by operators consuming the stream it was submitted to. This allows a reuse of a OutputTuple for multiple submissions, modifying its value before each submit.

  - setObject
```
void setObject(int attributeIndex,
               java.lang.Object value)
```
    Set the value of the attribute at the given index. The class of the object must match exactly the SPL mapping for the type. For mutable value types, such as Java arrays, care must be taken not to modify the value after it has been passed to OutputTuple.setObject(), otherwise changes to the object will also change the state of OutputTuple.
    
    Parameters:
    
    attributeIndex - Index of attribute to be set, zero is the tuple's first attribute.
    
    value - Value to set the attribute to, or null to set the value of an optional type to not present.
    
    Throws:
    
    java.lang.UnsupportedOperationException - Attribute value cannot be set from the value
    
    See Also:
    
    StreamSchema
  - setList
```
void setList(int attributeIndex,
             java.util.List<?> list)
```
    Set an attribute as a List. Only supported for attributes of, or attributes with optional values of, types LIST and BLIST.
    The passed in List is never modified.
    For SPL list types that have a Java array object type (for example list<int8>) a copy of list is made, changes to list do not change the value of this tuple's attribute.
    For all other SPL list types, changes to list do change the value of this tuple's attribute.
    For bounded lists (BLIST) excess elements beyond the bound are ignored. This matches SPL's semantics for bounded types, see BoundedType.
    
    Parameters:
    
    attributeIndex - Index of attribute to be set, zero is the tuple's first attribute.
    
    list - Value to set the attribute to, or null to set the value of an optional list to not present.
    
    Throws:
    
    java.lang.UnsupportedOperationException - Attribute value cannot be set from a List.
  - setSet
```
void setSet(int attributeIndex,
            java.util.Set<?> set)
```
    Set an attribute as a Set. Only supported for attributes of, or attributes with optional values of, types SET and BSET.
    For bounded sets (BSET) excess elements beyond the bound are ignored, though no guarantee is made as to which elements are set for the tuple. This matches SPL's semantics for bounded types, see BoundedType.
    
    Parameters:
    
    attributeIndex - Index of attribute to be set, zero is the tuple's first attribute.
    
    set - Value to set the attribute to, or null to set the value of an optional set to not present.
    
    Throws:
    
    java.lang.UnsupportedOperationException - Attribute value cannot be set from a Set.
  - setMap
```
void setMap(int attributeIndex,
            java.util.Map<?,?> map)
```
    Set an attribute as a Map. Only supported for attributes of, or attributes with optional values of, types MAP and BMAP.
    For bounded sets (BMAP) excess elements beyond the bound are ignored, though no guarantee is made as to which elements are set for the tuple. This matches SPL's semantics for bounded types, see BoundedType.
    
    Parameters:
    
    attributeIndex - Index of attribute to be set, zero is the tuple's first attribute.
    
    map - Value to set the attribute to, or null to set the value of an optional map to not present.
    
    Throws:
    
    java.lang.UnsupportedOperationException - Attribute value cannot be set from a Map.
  - setOptional
```
void setOptional(int attributeIndex,
                 java.util.Optional<?> optional)
```
    Set an optional attribute value using an Optional container. Only supported for attributes of type OPTIONAL. The type of the optional value, if present, must match the value type of the attribute's optional value.
    
    Parameters:
    
    attributeIndex - Index of attribute to be set, zero is the tuple's first attribute.
    
    optional - Optional container containing the value to set the attribute to, or an empty Optional to set the value to not present.
    
    Throws:
    
    java.lang.UnsupportedOperationException - Attribute value cannot be set from an Optional.

  - assign
```
void assign(Tuple sourceTuple)
```
    Set attributes of this tuple that have a matching attribute from sourceTuple. Attributes match if their name and type match, regardless of index within the schemas.
