stamps expression function

Returns a copy stamping string value.

Retrieves a stamping variable, usually from a downstream Copy node. See copy stamping.

This function retrieves string values. For floating-point number values, use stamp.

• scope: the path of the node to get the value from.

• token: the name of the variable to retrieve.

• value: the default string to use if token does not exist.

Returns the string value associated with the parameter named 'token' set in 'scope'. 'scope' is an operator path where the value is to be looked up from. If the token has not been set, then 'value' is returned. Stamping operators set these named tokens parameters recursively on themselves and all ancestor parents.

Examples of string stamping operators include the Apply Relationship DOP, and the Copy Data DOP.
