Method Detail

getAttribute

LogicalAttribute getAttribute()

Returns logical attribute object for the split attribute

Returns:

logical attribute object

setAttribute

void setAttribute(LogicalAttribute attribute)

Sets the split attribute

Parameters:

attribute - the split attribute

getComparisonOperator

ComparisonOperator getComparisonOperator()

Returns boolean operator used to perform the predicate checking

Returns:

boolean operator

setComparisonOperator

void setComparisonOperator(ComparisonOperator operator)

Sets the boolean operator used to perform the predicate checking

Parameters:

operator - boolean operator

getCategoryValues

java.util.List getCategoryValues()

Return list of categorical values with which some attribute value will be compared to.

Returns:

list of categorical values

getNumericalValue

java.lang.Double getNumericalValue()

Returns numerical value with which some attribute value will be compared to

Returns:

numerical value to compare

setNumericalValue

void setNumericalValue(java.lang.Double numericalValue)

Sets the numerical value with which some attribute value will be compared to

Parameters:

numericalValue - numerical value to compare

isNumerical

boolean isNumerical()

Numerical predicate type flag. If the predicate is numerical, than set to true.

Returns:

numerical predicate type flag.

setNumerical

void setNumerical(boolean numerical)

Returns visual string representation of the predicate.

Returns:

string representation of the predicate.

equals

boolean equals(java.lang.Object predicate)

Overrides:

equals in class java.lang.Object

isNullSplit

boolean isNullSplit()

If true, than split test is "ATTRIBUTE IS NULL".

Returns:
