Examples of AttributeExpression

org.codehaus.groovy.ast.expr.AttributeExpression
Represents an attribute access (accessing the field of a class) such as the expression "foo.@bar". @author James Strachan @version $Revision: 13404 $
org.geotools.filter.AttributeExpression
weka.core.AttributeExpression
A general purpose class for parsing mathematical expressions involving attribute values. Values can be provided in an array or in an Instance. Values are accessed in the expression by prefixing their index (starting at 1) with the character 'a'.
```
 Example expression: a1^2*a5/log(a7*4.0) 
```
Supported opperators: +, -, *, /, ^, log, abs, cos, exp, sqrt, floor, ceil, rint, tan, sin, (, ). @author Mark Hall @version $Revision: 5989 $
