                                                   throws java.lang.Exception

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,S extends java.sql.Statement>

Parameters:

statement - the proxied object

method - the method to invoke

parameters - the method invocation parameters

Returns:

an invocation strategy

Throws:

java.lang.Exception

See Also:

AbstractInvocationHandler.getInvocationStrategy(java.lang.Object, java.lang.reflect.Method, java.lang.Object[])

isSQLMethod

protected boolean isSQLMethod(java.lang.reflect.Method method)

Description copied from class: AbstractInvocationHandler

Indicates whether or not the specified method accepts a SQL string as its first parameter.

Overrides:

isSQLMethod in class AbstractInvocationHandler<D,S extends java.sql.Statement>

Parameters:

method - a method

Returns:

true, if the specified method accepts a SQL string as its first parameter, false otherwise.

See Also:

AbstractInvocationHandler.isSQLMethod(java.lang.reflect.Method)

Description copied from class: AbstractInvocationHandler

Called after method is invoked.

Overrides:

postInvoke in class AbstractInvocationHandler<D,S extends java.sql.Statement>
