SyntaxConjunctions

The AND, OR conjunctions are used to combine multiple predicates.

• Using AND every predicate must match in order for the expression to be matched.
• Using OR at least one predicate must match in order for the expression to be matched.

Given this expression:

x > 0 and (y < 2 or (z = 'foo' and p > 5)) and q = 4

An incoming structure with any of the following contents will be matched:

• x = 1 and q = 4 and y = 1
• x = 1 and q = 4 and z = 'foo' and p = 6

An incoming structure with any of the following contents will not be matched:

• x = -1 and q = 4 and y = 1
• x = 1 and q = 5 and y = 1
• x = 1 and q = 4 and y = 2
• x = 1 and q = 4 and z = 'bar' and p = 6
• x = 1 and q = 4 and z = 'foo'
