Re: [dali-dev] boolean getter method

Title: boolean getter method

The JavaBean spec[1] 8.3.2 says:

In addition, for boolean properties, we allow a getter method to match the pattern:

    public boolean is<PropertyName>();

This “is<PropertyName>” method may be provided instead of a “get<PropertyName>” method,
or it may be provided in addition to a “get<PropertyName>” method.

In either case, if the “is<PropertyName>” method is present for a boolean property then we will
use the “is<PropertyName>” method to read the property value.

An example boolean property might be:
    public boolean isMarsupial();
    public void setMarsupial(boolean m);

Actually, I take that back.  I don't think we've done that for (big B) Boolean attributes.  Only (small b) boolean attributes.

My understanding is that for boolean (and Boolean) attributes, either "is" *or* "get" is acceptable.  We've always analyzed and generated code (to my recollection) with this understanding.

Hi,

I've read some discussions about the signature of the accessor methods of an entity and I'm not certain if a getter with prefix 'get' is valid (in addition to the 'is' prefix). The EJB specification is also unclear (in my opinion) about this:

"… In this case, for every persistent property property of type T of the entity, there is a getter method, get-
Property, and setter method setProperty. For boolean properties, isProperty is an alternative name for
the getter method. …"

In other words, my question is:

For the getter method of an entity attributes of type 'boolean' is the only valid prefix 'is'  or the 'get' prefix is also allowed?
