Method Detail

addExpression

public void addExpression(Expression expr)
                   throws java.lang.Exception

Specified by:

addExpression in interface MultipleAryExpression

Throws:

java.lang.Exception

setExpressions

public void setExpressions(java.util.List<Expression> exprs)

Specified by:

setExpressions in interface MultipleAryExpression

getExpressions

public java.util.List<Expression> getExpressions()
