casa.util.unused.NumberLiteralNode

All Implemented Interfaces:

DataNode

(rck) The classes BooleanNode, DataNode, LogicalNode, LogicalPropoisitonTree, LogicalPropositionTreeException, LogicalPropositionTreeNode, NumberLiteralNode, PropositionNode, and StringLiteralNode taken together appear to be unused in CASA.

@Deprecated
public class NumberLiteralNode
extends Object
implements DataNode

A NumberLiteralNode object is a node in a LogicalPropositionTree that represents a literal number. It can evaluate to a number. A literal number is string in the form "-"?[0-9]*"."?[0-9]* that evaluates to a number.
A number is either a integer or floating point number.

Field Detail

number

BigDecimal number

Deprecated.

The numerical value of this node.

Constructor Detail

NumberLiteralNode

public NumberLiteralNode(String newNumber)

Deprecated.

Creates a new NumberLiteralNode with thes numerical value represented by the given string.

Parameters:

newNumber - The numerical value of the new node in a string representation.

NumberLiteralNode

public NumberLiteralNode(BigDecimal newNumber)

Deprecated.

Creates a new NumberLiteralNode with the given BigDecimal numerical value.

Parameters:

newNumber - The numerical value of the new node represented by a BigDecimal object.

NumberLiteralNode

public NumberLiteralNode(double newNumber)

Deprecated.

Creates a new NumberLiteralNode with the given double numerical value.

Parameters:

newNumber - The numerical value of the new node represented by a double.

NumberLiteralNode

public NumberLiteralNode(long newNumber)

Deprecated.

Creates a new NumberLiteralNode with the given long numerical value.

Parameters:

newNumber - The numerical value of the new node represented by a long.

Method Detail

isANumber

public boolean isANumber(PropertiesMap map)

Deprecated.

Determines whether this node can evaluate to a number with the given context. Returns true always.

Specified by:

isANumber in interface DataNode

Parameters:

map - The context within which we are evaluating the truth value. Defines the type and value of all properties in the tree during the evaluation.

Returns:

true always.

isAString

public boolean isAString(PropertiesMap map)

Deprecated.

Determines whether this node can evaluate to a string with the given context. Returns false always.

Specified by:

isAString in interface DataNode

Parameters:

map - The context within which we are evaluating the truth value. Defines the type and value of all properties in the tree during the evaluation.

Returns:

false always.

getNumber

public BigDecimal getNumber(PropertiesMap map)

Deprecated.

Retrieves this node's numerical value. Returns a BigDecimal containing the numerical value of this node.

Specified by:

getNumber in interface DataNode

Parameters:

map - The context within which we are evaluating the string value. Does not affect the result of this call since this node has a constant value.

Returns:

A BigDecimal containing the numerical value of this node.

getString

public String getString(PropertiesMap map)
                 throws LogicalPropositionTreeException

Deprecated.

Retrieves this node's string value. Since this node has only a numerical value, this function always throws an exception.

Specified by:

getString in interface DataNode

Parameters:

map - The context within which we are evaluating the string value. Does not affect the result of this call since this node has a constant value.

Returns:

Nothing, since this function always throws an exception.

Throws:

LogicalPropositionTreeException - Since this node has only a numerical value.
