public enum NodeType
extends Enum<NodeType>

The node type. This mostly determines how opcodes are parsed and rendered. Node types do not generally affect execution.

Enum Constant Detail

OperatorLeft

public static final NodeType OperatorLeft
A left associated operator. Operators are actually functions, however, setting to this type does affect how the opcode is rendered. http://en.wikipedia.org/wiki/Operator_associativity


OperatorRight

public static final NodeType OperatorRight
A right associated operator. Operators are actually functions, however, setting to this type does affect how the opcode is rendered. http://en.wikipedia.org/wiki/Operator_associativity


Leaf

public static final NodeType Leaf
A leaf, or terminal node. No children.


Function

public static final NodeType Function
A function.


Unary

public static final NodeType Unary
An unary operator.


None

public static final NodeType None
Unknown.

Method Detail

values

public static NodeType[] values()
Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows:
for (NodeType c : NodeType.values())
    System.out.println(c);

Returns:
an array containing the constants of this enum type, in the order they are declared

valueOf

public static NodeType valueOf(String name)
Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)

Parameters:
name - the name of the enum constant to be returned.
Returns:
the enum constant with the specified name
Throws:
IllegalArgumentException - if this enum type has no constant with the specified name
NullPointerException - if the argument is null

isOperator

public boolean isOperator()
Returns:
True, if this is an operator.
