org.eclipse.persistence.expressions.ListExpressionOperator
- All Implemented Interfaces:
Serializable
INTERNAL:
A ListExpressionOperator is used with an ArgumentListFunctionExpression. It is capable
of expanding the number of arguments it can be an operator for. It is built from a set
of start strings, a repeating set of separators and a set of termination strings
It typically represents a database function that has a variable list of arguments
e.g. COALESCE(arg1, arg2, arg3, .... argn)
In the example above "COALESCE(" is the start string, "," is the separator and ")" is the
end string

getDatabaseStrings
Returns an array of Strings that expects a query argument between each String in the array to form the Expression. The array is built from the defined startStrings, separators, and terminationStrings. Start strings and termination strings take precedence over separator strings. The first defined start string will be added to the array. All subsequent start strings are optional, meaning they will only be added to the array if there are argument spaces available. The defined set of separator strings will be repeated, as a complete set, as long as there are argument spaces available. The last defined termination string will be added to the array. All antecedent termination strings are optional, meaning they will only be added to the array if there are argument spaces available.- Overrides:
