3.5 Getting help from the JavaDoc and API references
The JavaDoc
API
reference for your
JVM
and project is always just a few keystrokes
away. Now you have no excuse for not reading the documentation!
3.5.1
Viewing method parameters
If you need to know what parameters the method you're calling requires, execute
the
View | Parameter Info
(
Ctrl+P
) command when your cursor is within the
braces of the appropriate method call. A pop-up window will display the method
parameters (or the entire method signature, if the
Show full signatures
option is
enabled in
Code Completion
settings). If more than one method matches the
name (and any parameters already passed to the method), all possible combina-
tions are listed, as shown in figure 3.7. You can navigate between the parameters
with the
Ta b
and
Shift+Tab
keys.
If you're using third-party libraries, and you want to have access to ex-
tended parameter information for the methods in them, make sure you
include these libraries' sources in the project source path. Otherwise,
you'll be able to only view the parameter types and not their names.
TIP
You can specify a couple of parameter-related options under the
Code Comple-
tion
settings control panel. The first option,
Autopopup
, automatically displays a
Figure 3.7 Viewing parameter information shows you what parameters are required for the
method you have selected.
