Method Summary

Modifier and Type	Method	Description
protected Object	doInvoke(Object o, Object[] actual)	Offers an extension point for subclasses (in alternate Uberspects) to alter the invocation after any array wrapping or varargs handling has already been completed.
String	getMethodName()	returns the method name used
Class	getReturnType()	returns the return type of the method invoked
private Object[]	handleVarArg(Class type, int index, Object[] actual)
Object	invoke(Object o, Object[] actual)	invocation method - called when the method invocation should be performed and a value returned
boolean	isCacheable()	specifies if this VelMethod is cacheable and able to be reused for this class of object it was returned for

Method Details

invoke

public Object invoke(Object o,
 Object[] actual)
              throws Exception

Description copied from interface: VelMethod

invocation method - called when the method invocation should be performed and a value returned

Specified by:

invoke in interface VelMethod

Returns:

The resulting object.

Throws:

Exception

See Also:

• VelMethod.invoke(java.lang.Object, java.lang.Object[])

doInvoke

protected Object doInvoke(Object o,
 Object[] actual)
                   throws Exception

Offers an extension point for subclasses (in alternate Uberspects) to alter the invocation after any array wrapping or varargs handling has already been completed.

Throws:

Exception

Since:

1.6

isVarArg

public boolean isVarArg()

Returns:

true if this method can accept a variable number of arguments

Since:

1.6

handleVarArg

private Object[] handleVarArg(Class type,
 int index,
 Object[] actual)

Parameters:

type - The vararg class type (aka component type of the expected array arg)

index - The index of the vararg in the method declaration (This will always be one less than the number of expected arguments.)

actual - The actual parameters being passed to this method

isCacheable

public boolean isCacheable()

Description copied from interface: VelMethod

specifies if this VelMethod is cacheable and able to be reused for this class of object it was returned for

Specified by:

isCacheable in interface VelMethod

Returns:

true if can be reused for this class, false if not

See Also:

• VelMethod.isCacheable()

getMethodName

• VelMethod.getMethodName()

getReturnType

public Class getReturnType()

Description copied from interface: VelMethod

returns the return type of the method invoked

Specified by:

getReturnType in interface VelMethod

Returns:

The return type of the method invoked
