collectExpressionInfo
public void collectExpressionInfo(ExpressionInfo info)
Description copied from class:Expression
Collects information about this expression tree. This default implementation add the expression's type to the set of misbehaving expression types.- Overrides:
collectExpressionInfo
in classExpression
- Parameters:
info
- the expression information object used to collect the information
-
computeHashCode
protected int computeHashCode()
Description copied from class:Expression
Method to compute the hash code for this object. The result returned from this method in cached in thefHashCode
field. If the value returned from the method equalsExpression.HASH_CODE_NOT_COMPUTED
(e.g.-1
) then the value is incremented by one.This default implementation calls
super.hashCode()
- Overrides:
computeHashCode
in classExpression
- Returns:
- a hash code for this object.
