Constructor Detail

If

public If()

If.

If

public If(Expression e,
          Statement thenStatement)

If.

Parameters:

e - an expression.

thenStatement - a statement.

If

public If(Expression e,
          Then thenBranch)

If.

Parameters:

e - an expression.

thenBranch - a then.

If

public If(Expression e,
          Then thenBranch,
          Else elseBranch)

If.

Parameters:

e - an expression.

thenBranch - a then.

elseBranch - an else.

If

public If(Expression e,
          Statement thenStatement,
          Statement elseStatement)

If.

Parameters:

e - an expression.

thenStatement - a statement.

elseStatement - a statement.

If

protected If(If proto)

If.

Parameters:

proto - an if.

Method Detail

deepClone

public If deepClone()

Deep clone.

Specified by:

deepClone in interface SourceElement

Specified by:

deepClone in interface Statement

Returns:

the object.

getLastElement

public SourceElement getLastElement()

Description copied from class: JavaSourceElement

Finds the source element that occurs last in the source. The default implementation returns this element, which is correct for all terminal program elements, and many non terminals such as statements and prefixed operators.

Specified by:

getLastElement in interface SourceElement

Overrides:

getLastElement in class JavaSourceElement

Returns:

the last source element in the syntactical representation of this element, may be equals to this element.

See Also:

JavaSourceElement.toSource(), JavaSourceElement.getEndPosition()

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.

See Also:

ChangeHistory.detached(recoder.java.ProgramElement, recoder.java.NonTerminalProgramElement, int)

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.

getThen

public Then getThen()

Get then.

Returns:

the then.

getElse

public Else getElse()

Get else.

Returns:

the else.

setThen

public void setThen(Then thenBranch)

Set then.

Parameters:

thenBranch - a then.

setElse

public void setElse(Else elseBranch)

Set else.

Parameters:

elseBranch - an else.

getBranchCount

public int getBranchCount()

Get the number of branches in this container.

Specified by:

getBranchCount in class BranchStatement

Returns:

the number of branches.

getBranchAt

public Branch getBranchAt(int index)

Specified by:

getBranchAt in class BranchStatement

accept

public void accept(SourceVisitor v)

Description copied from interface: SourceElement

Receive a visitor, for instance a pretty printer.

Specified by:

accept in interface SourceElement

Parameters:

v - a source visitor.

validate

public void validate()
              throws ModelException

Description copied from class: JavaProgramElement

Defaults to do nothing.

Specified by:

validate in interface ModelElement

Overrides:

validate in class JavaProgramElement

Throws:

ModelException
