Description copied from class: AbstractInvocationHandler

Returns the appropriate InvocationStrategy for the specified method. This implementation detects Wrapper methods; and Object.equals(java.lang.Object), Object.hashCode(), and Object.toString(). Default invocation strategy is DatabaseWriteInvocationStrategy.

Overrides:

getInvocationStrategy in class AbstractInvocationHandler<D,java.sql.ResultSet>

Parameters:

resultSet - the proxied object

method - the method to invoke

parameters - the method invocation parameters

Returns:

an invocation strategy

Throws:

java.lang.Exception
