WhileStatement

public WhileStatement()

Method Details

getExpression

public Expression getExpression()

Specified by:

getExpression in interface ILoopStatement

Returns:

The conditional expression.

setExpression

public void setExpression(Expression expression)

Parameters:

expression - The conditional expression.

getStatement

public Statement getStatement()

Specified by:

getStatement in interface ILoopStatement

Returns:

The statement to execute while the conditional expression evaluates to true.

setStatement

public void setStatement(Statement statement)

Parameters:

statement - The statement to execute while the conditional expression evaluates to true.

execute

public Object execute()

Execute the while statement

Specified by:

execute in interface IStatement

Overrides:

execute in class Statement

getLeastSignificantTerminalStatement_internal

protected ITerminalStatement getLeastSignificantTerminalStatement_internal(boolean[] bAbsolute)

Specified by:

getLeastSignificantTerminalStatement_internal in class Statement

getTerminalType

public TerminalType getTerminalType()

Description copied from interface: ITerminalStatement

Mostly this is important so we can weight the terminal types i.e., the ordinal in the enum is significant

Specified by:

getTerminalType in interface ITerminalStatement

toString

public String toString()

Description copied from class: Statement

Subclasses should return a String representing the parsed statement.

Specified by:

toString in class Statement
