Command Line
Query
|
|
- Using
QUERY <object> <method> :
- The query command gets information about a Java method that can be accessed via
the
INVOKE command.
- When only an object is given it will list all available methods. For example:
nM> query nxm.sys.lib.StringUtil
ClassName -> nxm.sys.lib.StringUtil
Constructors - all declared and inherited PUBLIC (1) ->
nxm.sys.lib.StringUtil
Methods - all declared and inherited PUBLIC (57) ->
addToStringBuffer cleanSplit
cleanString compareVersions
convertNullsToEmpty convertNullsToEmpty
equals getAcronym
getClass getClosingFensePos
getHTMLFor getKeyValue
getKeyValue getParsedElement
...
Note that some names will appear more than once. This indicates that there is more than
one version of this method that can be called (they have different number or type of
arguments).
- With Java 6 and earlier, given an object and a name QUERY lists the docs for that
method (or methods). For example:
nM> query nxm.sys.lib.StringUtil padLeft
ClassName -> nxm.sys.lib.StringUtil
Constructors - all declared and inherited PUBLIC (0) ->
Methods - all declared and inherited PUBLIC (2) ->
...
public static final java.lang.String padLeft(java.lang.String str, int
newlen, char padChar)
Return a new string of padded out to a pre-determined length by adding
characters to the left.
Examples: padLeft("cat", 5, '.') --> "..cat"
Parameters:
str - The string to pad.
newlen - The length to pad the string out to.
padChar - The character to pad the string with.
Returns:
The string padded on the left to match the specified length.
See Also:
padRight(String,int,char), padBoth(String,int,char)
Fields - all declared and inherited PUBLIC (including INTERFACE) (0) ->
QUERY is of limited use since Java 7 |
QUERY <object> is still helpful to get a full list of methods,
but the full method information is no longer available. It is suggested
that users reference the class API.
