Constructor Detail

InPlaceIfCommand

InPlaceIfCommand(Expression condition)

Creates an in-place alternative.

Parameters:

condition - the condition of the alternative

Method Detail

getCondition

public Expression getCondition()

Returns the condition expression.

Returns:

the condition

getThenExpressions

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

Returns the then expressions.

Returns:

the then expressions

getElseExpressions

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

Returns the else expressions.

Returns:

the else expressions, may be null

advanceState

protected void advanceState()

Description copied from class: InPlaceCommand

Changes among different states of sub-structures, e.g., then-part and else-part. Override if needed, else the respective call is just ignored.

Overrides:

advanceState in class InPlaceCommand<I extends VariableDeclaration>

append

protected void append(Expression ex)

Description copied from class: InPlaceCommand

Appends a sub-expression. An in-place command can have multiple sub-structures, that are sequentially switched to active via InPlaceCommand.advanceState().

Specified by:

append in class InPlaceCommand<I extends VariableDeclaration>

Parameters:

ex - the expression to append

close

protected Expression close(IStringParserFactory<I> factory)
                    throws VilException

Description copied from class: InPlaceCommand

Closes this in-place command by creating the real expression.

Specified by:

close in class InPlaceCommand<I extends VariableDeclaration>

Parameters:

factory - the factory used to create the real expression

Returns:

the real expression, may be null if optional / none shall be created

Throws:

VilException - if the provided information is not sufficient for creating an expression

append

protected void append(java.util.List<Expression> exprs)

Description copied from class: InPlaceCommand

Appends the sub-expressions in parse sequence to exprs leaving out this command as fallback.

Specified by:

append in class InPlaceCommand<I extends VariableDeclaration>

Parameters:

exprs - the expressions to add the sub-expressions to

replace

protected void replace(InPlaceCommand<I> cmd,
                       Expression expr)

Description copied from class: InPlaceCommand

Replaces cmd by expr.

Specified by:

replace in class InPlaceCommand<I extends VariableDeclaration>

Parameters:

cmd - the command to be replaced

expr - the replacing expression
