Attributes

Notes

You need not use the key attribute; it is present for backward compatibility.

Insert the itemName element in the streamMap to correspond with the column in the source stream that carries the RIC or symbol. If this column is part of the source stream's key, set the key attribute to true.

This element is one of the "pseudofields" that specify data items that are not part of the data feed coming directly from RMDS.

Example

<streamMap name="marketByOrderStream">
        <itemName key="true"/>
        <!-- serviceName / -->
        <sequenceNumber />
        <itemStale/>
        <dataField name="BID"/>
        <dataField name="ASK"/>
        <dataField name="TRDPRC_1"/>
        <dataField name="ACVOL_1"/>
        <dateTimeField timeName="TIMACT" dateName="ACTIV_DATE"/>
</streamMap>

The first column of the source stream is identified as the one that carries the RIC value of any update from the adapter. It is also identified as part of the stream's key.
