boolean	matches(Object left, Object right) This method differs from the parent in that we are not calling String.matches() because it does not match on a newline.

Method Detail

matches

public boolean matches(Object left,
              Object right)

This method differs from the parent in that we are not calling String.matches() because it does not match on a newline. Instead we are handling this case.

Overrides:

matches in class org.apache.commons.jexl2.JexlArithmetic

Parameters:

left - first value

right - second value

Returns:

test result.

equals

public boolean equals(Object left,
             Object right)

This method differs from the parent class in that we are going to try and do a better job of coercing the types. As a last resort we will do a string comparison and try not to throw a NumberFormatException. The JexlArithmetic class performs coercion to a particular type if either the left or the right match a known type. We will look at the type of the right operator and try to make the left of the same type.

Overrides:

equals in class org.apache.commons.jexl2.JexlArithmetic

lessThan

public boolean lessThan(Object left,
               Object right)

Overrides:

lessThan in class org.apache.commons.jexl2.JexlArithmetic

fixLeft

protected Object fixLeft(Object left,
             Object right)
