Indicates if the operator is unary, i.e. supports no comparison operands.

Specified by:
isUnary in class Operator
Returns:
true if the operator is unary, else false.

isBinary

public boolean isBinary()
Description copied from class: Operator
Indicates if the operator is binary, i.e. supports one comparison operand.

Specified by:
isBinary in class Operator
Returns:
true if the operator is binary, else false.

isTernary

public boolean isTernary()
Description copied from class: Operator
Indicates if the operator is ternary, i.e. supports two comparison operands.

Specified by:
isTernary in class Operator
Returns:
true if the operator is ternary, else false.
