ConstraintParser.Constraint (Mixin 0.16.5-0.8.7-1 API)

java.lang.Object
- org.spongepowered.asm.util.ConstraintParser.Constraint

Enclosing class:

ConstraintParser
```
public static class ConstraintParser.Constraint
extends java.lang.Object
```
A constraint. Constraints are parsed from string expressions which are always of the form:
```
<token>(<constraint>)
```
token is normalised to uppercase and must be provided by the environment.

constraint is an integer range specified in one of the following formats:
```
()
```
The token value must be present in the environment, but can have any value
```
(1234)
```
The token value must be exactly equal to 1234
```
(1234+)
(1234-)
(1234>)
```
All of these variants mean the same thing, and can be read as "1234 or greater"
```
(<1234)
```
Less than 123
```
(<=1234)
```
Less than or equal to 1234 (equivalent to 1234<)
```
(>1234)
```
Greater than 1234
```
(>=1234)
```
Greater than or equal to 1234 (equivalent to 1234 >)
```
(1234-1300)
```
Value must be between 1234 and 1300 (inclusive)
```
(1234+10)
```
Value must be between 1234 and 1234+10 (1234-1244 inclusive)
All whitespace is ignored in constraint declarations. The following declarations are equivalent:
```
token(123-456)
token   (   123 - 456   )
```
Multiple constraints should be separated by semicolon (;) and are conjoined by an implied logical AND operator. That is: all constraints must pass for the constraint to be considered valid.
