getType

public Class getType()

Specified by:

getType in interface Expression

Overrides:

getType in class UnaryExpression

evaluateBool

public boolean evaluateBool(EvaluationContext context)

Specified by:

evaluateBool in interface LogicalExpression

isCheckEquality

public boolean isCheckEquality()

toString

public String toString()

Overrides:

toString in class Object
