                       LongNode right,
                       MutableLongNode left)

Parameters:

Throws:

AssignOpNode

protected AssignOpNode(java.lang.String opString,
                       int presedence)

AssignOpNode

public AssignOpNode(LongNode right,
                    MutableLongNode left)

Parameters:

-

Throws:

AssignOpNode

public AssignOpNode()

Method Detail

getString

public java.lang.String getString()

Specified by:

getString in interface StringNode

getBoolean

public boolean getBoolean()

Specified by:

getBoolean in interface BooleanNode

getInt

public int getInt()

Specified by:

getInt in interface IntNode

getLong

public long getLong()

Specified by:

getLong in interface LongNode

doAssignment

public void doAssignment()

createOpNode

public OpNode createOpNode(Node right,
                           Node left)

Creates a new instace of this node type.

Overrides:

createOpNode in class OpNode

createOpNode

public OpNode createOpNode(java.util.Stack operands)
                    throws OperandException,
                           ExpInternalException

Creates a new node using the factory pattern. New node is initialized using the operands from the stack. OP node is either unary or binary operand node (takes 1 or 2 elements from the stack). This depends on the value of cardinality (see getCardinatlity()).

Overrides:

createOpNode in class OpNode

Parameters:

operands - Stack containing operands.

Returns:

Newly created OpNode initialized.

Throws:

OperandException - Throws OperandException if there aren't enough operands on the stack.

ExpInternalException

main

public static void main(java.lang.String[] args)

Test function for AssignOpNode

Parameters:

args - command line arguments
