EqualsExpression
public class EqualsExpression extends BinaryExpression (Code)
This class represents an "=" or "!=" expression. This class also provides the ability for the developer to prefix the "=" or "!=" with "$" to indicate that a case-insensitive comparison should be made, in which case the LHS and RHS are converted to strings first.


Field Summary
public  booleanignoreCase
    


Method Summary
public  booleanisIgnoreCase()
    
public  booleanisNot()
    
public  booleanisTrue(Object o, Query q)
     Return whether this expression evaluates to true.
Parameters:
  o - The current object to perform the expression on.
Parameters:
  q - The Query object.
public  voidsetIgnoreCase(boolean v)
    
public  voidsetNot(boolean v)
    
public  StringtoString()
     Return a string version of the expression.
