This class defines the interface for "Readable" data objects; that is, classes that implement this interface can appear on the righthand side of assignment and comparative clauses.
Method Summary | |
boolean |
cmpEq(AbleRd theRhs)
Comparison, equal to: compare the current value of this data object to the current value of theRhs. |
boolean |
cmpGt(AbleRd theRhs)
Comparison, greater than: compare the current value of this data object to the current value of theRhs. |
boolean |
cmpGtEq(AbleRd theRhs)
Comparison, greater than or equal to: compare the current value of this data object to the current value of theRhs. |
double |
cmpIs(AbleRd theRhs)
Comparison, fuzzy equal to: compare the current value of this data object to the current value of theRhs. |
boolean |
cmpLt(AbleRd theRhs)
Comparison, less than: compare the current value of this data object to the current value of theRhs. |
boolean |
cmpLtEq(AbleRd theRhs)
Comparison, less than or equal to: compare the current value of this data object to the current value of theRhs. |
boolean |
cmpNeq(AbleRd theRhs)
Comparison, not equal to: compare the current value of this data object to the current value of theRhs. |
boolean |
getBooleanValue()

java.lang.String |
getStringValue()
Retrieve the value of this data object as a string value. |
AbleLiteral |

public boolean cmpEq(AbleRd theRhs) throws AbleDataException
"==" is used for numeric and boolean compares; equals() is used for Object compares; and Collator.equals() is used for String compares.
theRhs
- The right-hand side of the comparison.
public boolean cmpGt(AbleRd theRhs) throws AbleDataException
">" is used for numeric compares; Collator.compare() is used for String compares. Use of other data types on the left-hand side causes an exception.
theRhs
- The right-hand side of the comparison.
public boolean cmpGtEq(AbleRd theRhs) throws AbleDataException
">=" is used for numeric compares; Collator.compare() is used for String compares. Use of other data types on the left-hand side causes an exception.
theRhs
- The right-hand side of the comparison.
public double cmpIs(AbleRd theRhs) throws AbleDataException
Fuzzy membership is used for the compare.
theRhs
- The right-hand side of the comparison.
This must be a fuzzy set.
public boolean cmpLt(AbleRd theRhs) throws AbleDataException
"<" is used for numeric compares; Collator.compare() is used for String compares. Use of other data types on the left-hand side causes an exception.
theRhs
- The right-hand side of the comparison.
public boolean cmpLtEq(AbleRd theRhs) throws AbleDataException
"<=" is used for numeric compares; Collator.compare() is used for String compares. Use of other data types on the left-hand side causes an exception.
theRhs
- The right-hand side of the comparison.
public boolean cmpNeq(AbleRd theRhs) throws AbleDataException
"!=" is used for numeric and boolean compares; ! equals() is used for Object compares; and ! Collator.equals() is used for String compares.
theRhs
- The right-hand side of the comparison.
