Owning Palette: Low Level Apple Events VIs

Requires: Base Development System (Mac OS X)

Creates a string describing an Apple event comparison record, which indicates how to compare an Apple event object with another Apple event object or a descriptor record.

For example, you can use the output comparison descriptor as an argument to the AESend VI, or as an argument to AECreate Object Specifier to build a more complex descriptor string.

comparison operator is a descriptor type string that describes the comparison operation to perform on the operands. You can use the following standard set of comparisons:

> KAEGreaterThan The value of operand1 is greater than the value of operand 2.
>= KAEGreaterThanEquals The value of operand 1 is greater than or equal to the value of operand 2.
= KAEEquals The value of operand 1 is equal to the value of operand 2.
< KAELessThan The value of operand 1 is less than the value of operand 2.
<= KAELessThanEquals The value of operand 1 is less than or equal to the value of operand 2.
bgwt KAEBeginsWith The value of operand 1 begins with the value of operand 2. For example, the string operand begins with the string opera.
ends KAEEndsWith The value of operand 1 ends with the value of operand 2. For example, the string operand ends with the string and.
cont KAEContains The value of operand 1 contains the value of operand 2. For example, the string operand contains the string era.
operand 1 is an AppleEvent object specifier descriptor string. It indicates the first object in the comparison to perform.
operand 2 is an AppleEvent record descriptor string. It can be an object specifier descriptor string or any other record descriptor string with a value to compare to the value of operand 1.
comparison descriptor is the AppleEvent descriptor string.
