Custom Metadata Selector (.^myCustomMetadata)
Returns the value of custom metadata. Metadata can be associated with any value by using the as operator.
The following example uses userName.^myCustomMetadata to return the value of custom metadata that is defined as a variable (named userName) in the header of the script as a DataWeave script. For comparison, the example also returns the value of userName.
DataWeave Script:
%dw 2.0
output application/json
var userName = “DataWeave” as String {myCustomMetadata: “customMetadataValue”}
—
{
“valueOfVariableMetaData” : userName.^myCustomMetadata,
“valueOfVariable” : userName,
}
The output of the script is “customMetadataValue” for the value of the custom metadata and “DataWeave” for value of the userName variable.
Output JSON:
{
“valueOfVariableMetaData”: “customMetadataValue”,
“valueOfVariable”: “DataWeave”
}
