Class SumNode

java.lang.Object

psdi.common.parse.TreeNodeAdapter

psdi.common.parse.SumNode

All Implemented Interfaces:

TreeNode

public class SumNode
extends TreeNodeAdapter

The Sum node. This node takes two nodes and combines them using addition, subtraction, or String concatenation. The datatype of this node depends on the datatypes of the operands. Strings can be concatenated with Strings, Numbers can be summed with numbers, or a date and a number can be summed. Two dates can't be added together.

Constructor Detail

SumNode

public SumNode(TreeNode oper1,
               java.lang.String operator,
               TreeNode oper2)

Constructor takes operands

Method Detail

validate

public void validate(MboRemote mbo)
              throws MXException,
                     java.rmi.RemoteException

Determine if there is a valid combination of parameters. Throws an exception if there is not. Also has the side effect of setting up the calculation.

Throws:

MXException

java.rmi.RemoteException

getBoolean

public boolean getBoolean(MboRemote mbo)
                   throws MXException,
                          java.rmi.RemoteException

This node cannot be a boolean.

Throws:

MXException

java.rmi.RemoteException

getDate

public java.util.Date getDate(MboRemote mbo)
                       throws MXException,
                              java.rmi.RemoteException

This node can be a date, but an exception will be thrown if the operands are not a a date and a number.

Throws:

MXException

java.rmi.RemoteException

getString

public java.lang.String getString(MboRemote mbo)
                           throws MXException,
                                  java.rmi.RemoteException

Evaluates the node and returns it's value as a String.

Throws:

MXException

java.rmi.RemoteException

getDouble

public double getDouble(MboRemote mbo)
                 throws MXException,
                        java.rmi.RemoteException

Evaluates the node and returns it's value as a double.

Throws:

MXException

java.rmi.RemoteException

getInt

public int getInt(MboRemote mbo)
           throws MXException,
                  java.rmi.RemoteException

Evaluates the node and returns it's value as an integer.

Throws:

MXException

java.rmi.RemoteException

getNodeDataType

public int getNodeDataType()

The data type of this node depends on the operation & maybe the types of the operands. This node can potentially be a String or Number.

getNodeDataType

public int getNodeDataType(MboRemote mbo)
                    throws MXException,
                           java.rmi.RemoteException

Better check with mbo information

Overrides:

getNodeDataType in class TreeNodeAdapter

Throws:

MXException

java.rmi.RemoteException

setOperands

public void setOperands(MboRemote mbo,
                        java.util.Vector operands)
                 throws MXException,
                        java.rmi.RemoteException

Description copied from interface: TreeNode

Sets the operands for custom class.

Throws:

MXException

java.rmi.RemoteException
