Specified by:

getLevel in interface IndentableElement

Returns:

the level of the BIND

setVariable

public void setVariable(java.lang.String var)

Set the bounded variable.

Parameters:

var - the variable

getInputVariables

public java.util.Set<java.lang.String> getInputVariables()

Return the input variables.

Returns:

the input variables

addExpression

public void addExpression(Expression expression,
                          short operator)

Add an expression.

Parameters:

expression - the expression

operator - the operator

addExpression

public void addExpression(Expression expression)

Add an expression with the default AND operator.

Parameters:

expression - the expression

checkValidity

public boolean checkValidity()

Check the validity of the BIND expression.

Specified by:

checkValidity in class ExpressionList

Returns:

true if the BIND expression is valid

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object obj)

Overrides:

equals in class java.lang.Object
