bindParameters

public static java.lang.String bindParameters(java.lang.String queryStub,
java.lang.Object... parameters)

Formats parameters values for the UES query string. It provides a mechanism for creating the right textual representation of objects such as dates etc.
example: Input string queryStub = "dateFrom > ?" and 1 parameter = Date(December 31th, 2010 at 11 pm) are formatted into the string "dateFrom > '2010-12-31T23:00'" which conforms the UES query syntax.
Note that it is not permitted to use placeholder '?' for other purposes than parameters values binding.

Parameters:

queryStub - ues query string optionally containing character '?' as a placeholder for the query parameters value.

parameters - Objects containing values of parameters. There need to be an object for every placeholder '?' in stub. Only java String, Boolean, Long/Integer/Short/Byte, Date and UESURI classes are supported.

Returns:

UES query string with parameters bound.
