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 class Expression

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 the fHashCode field. If the value returned from the method equals Expression.HASH_CODE_NOT_COMPUTED (e.g. -1) then the value is incremented by one.

This default implementation calls super.hashCode()

Overrides:

computeHashCode in class Expression

Returns:

a hash code for this object.

toString

public String toString()

Overrides:

toString in class Object
