Constructor Detail

CompositeExpression

CompositeExpression()

Constructor for serialization.

CompositeExpression

public CompositeExpression(java.util.List<Expression> expressionList)

Creates a new composite expression.

Parameters:

expressionList - a list with expressions

CompositeExpression

public CompositeExpression(Expression... expressions)

Creates a new composite expression.

Parameters:

expressions - the expressions

Method Detail

getExpressionsCount

public int getExpressionsCount()

Returns the number of expression.

Specified by:

getExpressionsCount in interface IExpressionIterator

Returns:

the number of expressions

getExpression

public Expression getExpression(int index)

Returns the specified expression.

Specified by:

getExpression in interface IExpressionIterator

Parameters:

index - the 0-based index of the expression

Returns:

the expression

Throws:

java.lang.IndexOutOfBoundsException - if index<0 || index>=#getExpressionListCount()

setExpression

public void setExpression(int index,
                          Expression expr)

Replaces the specified expression. Handle with care!

Parameters:

index - the 0-based index of the expression

expr - the replacing expression

Throws:

java.lang.IndexOutOfBoundsException - if index<0 || index>=#getExpressionListCount()

inferType

public TypeDescriptor<?> inferType()
                            throws VilException

Description copied from class: Expression

Infers the type of this expression including the type of the contained sub-expressions.

Specified by:

inferType in class Expression

Returns:

the type of this expression

Throws:

VilException - in case that inferring the type fails

accept

public java.lang.Object accept(IExpressionVisitor visitor)
                        throws VilException

Description copied from class: Expression

Visits the expression.

Specified by:

accept in class Expression

Parameters:

visitor - the visitor

Returns:

the result of visiting this expression (may be null)

Throws:

VilException - in case that visiting fails (e.g., execution)
