Method Summary
`java.lang.String` | `currentName()` return name of parameter currently being iterated - ugly hack...
`void` | `forAllConstructorParams(java.lang.String template)` Iterates over all parameters of current constructor and evaluates the body of the tag for each method.
`void` | `forAllMethodParams(java.lang.String template)` Iterates over all parameters of current method and evaluates the body of the tag for each method.
`void` | `forAllParameterTypes(java.lang.String template, java.util.Properties attributes)` Gets the value of the parameter specified by paramName of current tag, and assuming the value has the format of a typical method definition extracts of parameter types out of it and evaluates the body for each parameter type.
`static java.lang.String` | `getMethodParamTypeFor(xjavadoc.XParameter param)`
`void` | `ifHasParams(java.lang.String template, java.util.Properties attributes)` Evaluates the body of the tag if current method/constructor has parameters.
`java.lang.String` | `methodParamDescription()` The `methodParamDescription` method returns the comment text associated with the ParamTag for the current Parameter
`java.lang.String` | `methodParamName()` Returns the name of the current method parameter, current method parameter is set inside a forAllMethodParams tag in each iteration.
`java.lang.String` | `methodParamType(java.util.Properties attributes)` Returns the type of the current method parameter, current method parameter is set inside a forAllMethodParams tag in each iteration.
`java.lang.String` | `parameterList(java.util.Properties attributes)` Iterates over all parameters in current method and returns a string containing definition of all those parameters.
