Method Detail

setExpression1

public void setExpression1(Expression expr1)

Description copied from interface: AryExpression

Set the first expression.

Specified by:

setExpression1 in interface AryExpression

Parameters:

expr1 - the expression

setExpression2

public void setExpression2(Expression expr2)

Description copied from interface: AryExpression

Set the second expression.

Specified by:

setExpression2 in interface AryExpression

Parameters:

expr2 - the expression

getExpression1

public Expression getExpression1()

Description copied from interface: AryExpression

Return the first expression.

Specified by:

getExpression1 in interface AryExpression

Returns:

the expression

getExpression2

public Expression getExpression2()

Description copied from interface: AryExpression

Return the second expression.

Specified by:

getExpression2 in interface AryExpression

Returns:

the expression

getVariables

public java.util.Map<java.lang.String,Variable> getVariables()

Description copied from interface: Expression

Return the variables used by this expression. Note that this method will not return any internal variables declared by the expression. For example, in the following expression: int c=a+b, only "a" and "b" will be returned.

Specified by:

getVariables in interface Expression

Returns:

the variables used by this expression
