[T5] filter on parameters

[manuel aldana <al...@gmx.de>]

Hi,

a question on @Parameter:

@Parameter
private String param;

1) How is it possible to filter a passed param (e.g. manipulating the 
value)? Using getters and setters for that would not work.
2) How can I make the parameter available to the template (e.g. to 
render this), i.e. want to have it passed as a parameter but want to 
render it as a property in my component.

thanks.

Generally, the "setupRender" phase is what you want to use:

@SetupRender //annotation is redundant if the method name is setupRender
void setupRender() {
	//manipulate "param" parameter here...
	param = param==null?null:param.replaceAll("a","b");
}

This method will be called before the component renders.

@Parameter
@Property
private String param;

Or:

@Parameter
private String param;

public String getParam() {
	return param;
}
