Interface AbleWr

All Known Implementing Classes:

AbleLhs

public interface AbleWr

This class defines the interface for "Writable" data objects; that is, classes that implement this interface can appear on the lefthand side of assignment clauses.

Method Summary

java.lang.String	arlDclString() Return a formal rule language "declaration" string that describes this data object.
void	asgnEq(AbleRd theRhs) Assignment (boolean): assign the current value of theRhs to this data object.
void	asgnIs(AbleRd theRhs) Assignment (fuzzy): assign the current value of theRhs to this data object.
void	asgnIs(AbleRd theRhs, double theTruthValue) Assignment (fuzzy): assign the current value of theRhs to this data object, correlated with the specified truth value.
void	setBooleanValue(boolean theNewValue) Set the value of this data object from a boolean value.
void	setFuzzyValue(AbleFuzzySet theNewValue) Set the value of this data object from a fuzzy value.
void	setGenericValue(java.lang.Object theNewValue) Set the value of this data object from an object.
void	setNumericValue(double theNewValue) Set the value of this data object from a numeric value.
void	setStringValue(java.lang.String theNewValue) Set the value of this data object from a string value.
void	setValue(AbleLiteral theNewValue) Set the value of this data object from a literal object.
java.lang.String	xmlCWrString() Return a formal XML "clause write" string that describes this data object.
java.lang.String	xmlDclString() Return a formal XML "declaration" string that describes this data object.

Method Detail

setBooleanValue

public void setBooleanValue(boolean theNewValue)
                     throws AbleDataException

Set the value of this data object from a boolean value.

Parameters:

theNewValue - A boolean value.

Throws:

AbleDataException - If the value of this object cannot be represented as a boolean value.

setFuzzyValue

public void setFuzzyValue(AbleFuzzySet theNewValue)
                   throws AbleDataException

Set the value of this data object from a fuzzy value.

Parameters:

theNewValue - A fuzzy set.

Throws:

AbleDataException - If the value of this object cannot be represented as a fuzzy value.

setGenericValue

public void setGenericValue(java.lang.Object theNewValue)
                     throws AbleDataException

Set the value of this data object from an object.

Parameters:

theNewValue - Any type of Object.

Throws:

AbleDataException - If the value of this object cannot be derived from the specified Object.

setNumericValue

public void setNumericValue(double theNewValue)
                     throws AbleDataException

Set the value of this data object from a numeric value.

Parameters:

theNewValue - Any number.

Throws:

AbleDataException - If the value of this object cannot be represented as a numeric value.

setStringValue

public void setStringValue(java.lang.String theNewValue)
                    throws AbleDataException

Set the value of this data object from a string value.

Parameters:

theNewValue - A string.

Throws:

AbleDataException - If the value of this object cannot be represented as a string value.

setValue

public void setValue(AbleLiteral theNewValue)
              throws AbleDataException

Set the value of this data object from a literal object.

Parameters:

theNewValue - An Able literal of any type. An attempt is made to convert the literal to an appropriate type before assigning it to this "writable" object.

Throws:

AbleDataException - If the value of this object cannot be determined from the literal object.

arlDclString

public java.lang.String arlDclString()

Return a formal rule language "declaration" string that describes this data object.

Returns:

A String describing the data object in formal rule language.

xmlDclString

public java.lang.String xmlDclString()

Return a formal XML "declaration" string that describes this data object.

Returns:

A String describing the data object in XML.

xmlCWrString

public java.lang.String xmlCWrString()

Return a formal XML "clause write" string that describes this data object.

Returns:

A String describing the data object in XML.

asgnEq

public void asgnEq(AbleRd theRhs)
            throws AbleDataException

Assignment (boolean): assign the current value of theRhs to this data object.

Parameters:

theRhs - The right-hand, or source, side of the assignment.

Throws:

AbleDataException - If the right-hand side cannot be converted (if necessary) and assigned to this data object.

asgnIs

public void asgnIs(AbleRd theRhs)
            throws AbleDataException

Assignment (fuzzy): assign the current value of theRhs to this data object.

Parameters:

theRhs - The right-hand, or source, side of the assignment. This must be a fuzzy set.

Throws:

AbleDataException - If the right-hand side cannot be converted (if necessary) and assigned to this data object.

asgnIs

public void asgnIs(AbleRd theRhs,
                   double theTruthValue)
            throws AbleDataException

Assignment (fuzzy): assign the current value of theRhs to this data object, correlated with the specified truth value.

Parameters:

theRhs - The right-hand, or source, side of the assignment. This must be a fuzzy set.

theTruthValue - the truth value with which theRhs is to be correlated.

Throws:

AbleDataException - If the right-hand side cannot be converted (if necessary) and assigned to this data object.
