Method bodies look largely like Java. References to java classes must be fully qualified. Several special variables are used:
- $0 first parameter, equivalent to this in Java code (and can't be used when creating a static method)
- $1, $2, ... actual parameters to the method
- $args all the parameters as an Object[]
- $r the return type of the method, typically used as return ($r) .... $r is valid with method that return void. This also handles conversions between wrapper types and primitive types.
- $w conversion from primitive type to wrapper type, used as ($w) foo() where foo() returns a primitive type and a wrapper type is needed
ClassFab instances are not thread safe.
ClassFab instances are created by a {@link org.apache.tapestry.ioc.services.ClassFactory}.
