Literals

Certain literals are used for the rule language grammar.

The TIBCO BusinessEvents rule language supports these literals:

int
One or more digits without a decimal. May be positive or negative.

Examples: 

4   45   -321   787878

long
An integer literal suffixed with the letter L. The suffixed L can be either upper or lower case, but keep in mind that the lower case L (l) can be difficult to distinguish from the number one (1). 


Examples: 

0l   0777L   0x100000000L   2147483648L   0xC0B0L

double
A number that can represent fractional values. D suffix is optional unless there is no decimal point or exponent.


Examples: 

1D   1e1   2.   .3   0.0D   3.14   1e-9d   1e137

String
Zero or more characters enclosed in double quotes (""). The string must be on one line. Use \n for newlines. Use the plus sign (+) to concatenate string segments.


Examples:

  • Empty string: "" (quotes with no space).
  • Space character: " " (quotes with one or more spaces).
  • Strings with values: 
    "P0QSTN3" "The quick brown fox had quite a feast!"
  • Strings spanning multiple lines: 
 
    "The quick brown fox " +
    "had quite a feast!"
boolean
One of these two values:   true   false
Null
This value:   null
