LoopEnd

Stream Information

Input	Format	All
	Number of Inputs	1
	Description	Accepts all stream types.
Output	Format	NONE
	Description	The input stream is copied to the output stream.

Component Properties

Name	Data Type	Mapping	Description
LoopStart	componentName	-	Specifies a components which starts loop. The component list is displayed in the dropdown list.
ReturnStream	choice	-	Specifies whether multiple streams are to be packed in the case of looping. For details, please refer to following topic "Output format". PackRecords - Pack streams Last - Output only last stream PackStreams - Output streams as a contaitner

Loop

Ends looping. When this component completes execution, the flow execution returns control to the last loop initiator component executed prior to this End component.

Transaction

Commit	Do nothing
Rollback	Do nothing

Exceptions

This component never causes any exceptions.

This component's behavior

When this component is used, the part from the component specified by LoopStart to this component is handled as a sub-flow internally. Please note that:

• If there is another loop start component, the loop section which starts from that component also ends this LoopEnd.
• Branches like parallel processing has to be ended in the loop section. If the link is connected to outside of loop section, the compile error occurs.
• Loop section can be nested by using some LoopEnd components. Please take care about correspondence of loop sections.
• If you branch the flow with a component like BranchStrat in the loop section and it ends with Break component, next component of this LoopEnd is processed after Break component exit loop section.

Output fomat

By ReturnStream, specifies a format of output stream when the flow is looped. By this property, output streamm can be packed as one stream, or can be put in a stream container.

Only when all input stream, that are also output stream into this component, should have the same type and the same fields. Different streams by branching flow cannot be packed.

If there is no loop section and input stream is only one, the last stream becomes output stream. In the case of MIME, each part itself, not multipart, is output. In the case of XML, no error occurs when it has no field definitions.

Packing stream

When "Pack streams" is specified, input streams are packed according to the stream type.

Binary, Text	Streams are concatenated.
Record, CSV, FixedLength	All records in the streams are joined in one output stream.
ParameterList	The value of last stream is set except for String[] type. The values of String[] type field are joined.
XML	XML is re-constructed according to field definition. If field definition is not defined, error occurs.
MIME	Multipart MIME is generated.

Stream container

"Stream container" is used in the case to attach the multiple streams to a single mail.
