Method Summary

Type getDataType()
          Figure out the type of the binary expression by looking at the types of the operands.

String getDisplayText()
          Returns additional display text for the AST node.

Node getLeftHandOperand()
          Retrieves the left-hand operand of the operator.

Node getRightHandOperand()
          Retrieves the right-hand operand of the operator.

void initialize()
          Called by the tree walker during hql-sql semantic analysis after the operator sub-tree is completely built.

void setScalarColumnText(int i)
          Appends AST nodes that represent the columns after the current AST node.
