Constructor Detail

Assert

public Assert()

Trivial constructor.

Assert

public Assert(Expression cond)

Assert.

Parameters:

cond - the condition expression (may not be null).

Assert

public Assert(Expression cond,
              Expression msg)

Assert.

Parameters:

cond - the condition expression (may not be null).

msg - the message expression.

Assert

protected Assert(Assert proto)

Assert.

Parameters:

proto - an assert.

Method Detail

deepClone

public Assert 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.

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.

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

getCondition

public Expression getCondition()

Gets the condition expression.

Returns:

the expression.

setCondition

public void setCondition(Expression expr)

Sets the condition expression.

Parameters:

expr - an expression.

getMessage

public Expression getMessage()

Gets the message expression.

Returns:

the expression.

setMessage

public void setMessage(Expression expr)

Sets the message expression.

Parameters:

expr - an expression.

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.
