Constructor Detail

ExpressionJumpStatement

public ExpressionJumpStatement()

Expression jump statement.

ExpressionJumpStatement

public ExpressionJumpStatement(Expression expr)

Expression jump statement.

Parameters:

expr - an expression.

ExpressionJumpStatement

protected ExpressionJumpStatement(ExpressionJumpStatement proto)

Expression jump statement.

Parameters:

proto - an expression jump statement.

Method Detail

makeParentRoleValid

public void makeParentRoleValid()

Make parent role valid.

Specified by:

makeParentRoleValid in interface NonTerminalProgramElement

Overrides:

makeParentRoleValid in class JavaNonTerminalProgramElement

replaceChild

public boolean replaceChild(ProgramElement p,
                            ProgramElement q)

Replace a single child in the current node. The child to replace is matched by identity and hence must be known exactly. The replacement element can be null - in that case, the child is effectively removed. The parent role of the new child is validated, while the parent link of the replaced child is left untouched.

Specified by:

replaceChild in interface NonTerminalProgramElement

Parameters:

p - the old child.

p - the new child.

Returns:

true if a replacement has occured, false otherwise.

Throws:

java.lang.ClassCastException - if the new child cannot take over the role of the old one.

getExpressionCount

public int getExpressionCount()

Get the number of expressions in this container.

Specified by:

getExpressionCount in interface ExpressionContainer

Returns:

the number of expressions.

getExpressionAt

public Expression getExpressionAt(int index)

Specified by:

getExpressionAt in interface ExpressionContainer

getExpression

public Expression getExpression()

Get expression.

Returns:

the expression.

setExpression

public void setExpression(Expression expr)

Set expression.

Parameters:

expr - an expression.

getChildCount

public int getChildCount()

Returns the number of children of this node.

Specified by:

getChildCount in interface NonTerminalProgramElement

Returns:

an int giving the number of children of this node

getChildAt

public ProgramElement getChildAt(int index)

Returns the child at the specified index in this node's "virtual" child array

Specified by:

getChildAt in interface NonTerminalProgramElement

Parameters:

index - an index into this node's "virtual" child array

Returns:

the program element at the given position

Throws:

java.lang.ArrayIndexOutOfBoundsException - if index is out of bounds

getChildPositionCode

public int getChildPositionCode(ProgramElement child)

Description copied from interface: NonTerminalProgramElement

Returns the positional code of the given child, or -1 if there is no such child. The result contains an encoding of the relative position of the child as well as the role it has been playing in this parent element. This information is required internally for proper undo of transformations and is to be delivered to the detached method of the ChangeHistory.

Specified by:

getChildPositionCode in interface NonTerminalProgramElement

Parameters:

child - the exact child to look for.

Returns:

the positional code of the given child, or -1.
