Custom Metadata Selector (.^myCustomMetadata)

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”

}
