PROPOSAL: Method and Field Literals (original) (raw)

with getField, I only see 834 results.

A search for "finally in.close", which only covers a small slice of
ARM's bailiwick returns ~31100 results.

A -lot- of the method literals in that google code search result
involve checking if a certain method exists in a certain class. I
would assume the module system takes care of most of these calls (as
its effectively a version check). That should take care of about 3000
of those 7000 already.

In Glazed Lists we have an interface called TableFormat that maps a value object to its columns for a table. A concise API to access methods would be convenient: TableFormat songsTableFormat = new TableFormat.Builder() .addColumn("Name", Song#getSongName()) .addColumn("Track #", Song#getTrackNumber()) .addColumn("Artist", Song#getArtist()) .addColumn("Album", Song#getAlbum()) .build(); Google Code Search suggests another 7,000 immediate candidates: http://www.google.com/codesearch?hl=en&lr=&q=%5C.class%5C.getMethod%5C%28%5C%22&sbtn=Search This includes code from Apache HTTP client, Log4J, Ant, JPA, SwingX, EJB, SAX, Google Collections, GWT, Hibernate, Seam, MySQL, Equinox, Eclipse... you name it.
