Table 29.2. Binary Operators for the Simple Language
Operator	Description
`==`	Equals.
`>`	Greater than.
`>=`	Greater than or equals.
`<`	Less than.
`<=`	Less than or equals.
`!=`	Not equal to.
`contains`	Test if LHS string contains RHS string.
`not contains`	Test if LHS string does not contain RHS string.
`regex`	Test if LHS string matches RHS regular expression.
`not regex`	Test if LHS string does not match RHS regular expression.
`in`	Test if LHS string appears in the RHS comma-separated list.
`not in`	Test if LHS string does not appear in the RHS comma-separated list.
`is`	Test if LHS is an instance of RHS Java type (using Java `instanceof` operator).
`not is`	Test if LHS is not an instance of RHS Java type (using Java `instanceof` operator).
`range`	Test if LHS number lies in the RHS range (where range has the format, `'`min`...`max`'`).
`not range`	Test if LHS number does not lie in the RHS range (where range has the format, `'`min`...`max`'`).

The binary operators for simple language predicates are shown in Table 29.3, “Unary Operators for the Simple Language”.

Table 29.3. Unary Operators for the Simple Language
Operator	Description
`++`	Increment a number by 1.
`--`	Decrement a number by 1.
`\n`	The newline character.
`\r`	The carriage return character.
`\t`	The tab character.
`\`	(Obsolete) Since Camel version 2.11, the backslash escape character is not supported.

The conjunctions shown in Table 29.4, “Conjunctions for Simple Language Predicates” can be used to combine two or more simple language predicates.

Table 29.4. Conjunctions for Simple Language Predicates
Operator	Description
`&&`	Combine two predicates with logical and.
`\|\|`	Combine two predicates with logical inclusive or.
`and`	Deprecated. Use `&&` instead.
`or`	Deprecated. Use `\|\|` instead.
