It refers to child evaluations that occur as a result of the nodes' evaluation. Constructor Summary public   Evaluation(SimpleNode node, Object source)      Constructs a new "get" Evaluation from the node and source given. public   Evaluation(SimpleNode node, Object source, boolean setOperation)      Constructs a new Evaluation from the node and source given. Method Summary public  void addChild(Evaluation child)      Adds a child to the list of children of this evaluation. public  Throwable getException()      Returns the exception that occurred as a result of evaluating the Evaluation, or null if no exception occurred. public  Evaluation getFirstChild()      Returns the first child of this evaluation. public  Evaluation getFirstDescendant()      Gets the first descendent. public  Evaluation getLastChild()      Returns the last child of this evaluation. public  Evaluation getLastDescendant()      Gets the last descendent. public  Evaluation getNext()      Returns the next sibling of this evaluation. public  SimpleNode getNode()      public  Evaluation getParent()      Returns the parent evaluation of this evaluation. public  Evaluation getPrevious()      Returns the previous sibling of this evaluation. public  Object getResult()      Returns the result of the Evaluation, or null if it was a set operation. public  Object getSource()      Returns the source object on which this Evaluation operated. public  void init(SimpleNode node, Object source, boolean setOperation)      Reinitializes this Evaluation to the parameters specified. public  boolean isSetOperation()      Returns true if this Evaluation represents a set operation. public  void reset()      Resets this Evaluation to the initial state. public  void setException(Throwable value)      Sets the exception that occurred as a result of evaluating the Evaluation. public  void setNode(SimpleNode value)      Sets the node of the evaluation. public  void setResult(Object value)      Sets the result of the Evaluation. public  void setSetOperation(boolean value)      Marks the Evaluation as a set operation if the value is true, else marks it as a get operation. public  void setSource(Object value)      Sets the source of the evaluation. public  String toString(boolean compact, boolean showChildren, String depth)      Produces a String value for the Evaluation. public  String toString(boolean compact, String depth)      Produces a String value for the Evaluation. public  String toString()      Returns a String description of the Evaluation. Constructor Detail Evaluation public Evaluation(SimpleNode node, Object source)(Code) Constructs a new "get" Evaluation from the node and source given. Evaluation public Evaluation(SimpleNode node, Object source, boolean setOperation)(Code) Constructs a new Evaluation from the node and source given. If setOperation is true this Evaluation represents a "set" as opposed to a "get". Method Detail addChild public void addChild(Evaluation child)(Code) Adds a child to the list of children of this evaluation. The parent of the child is set to the receiver and the children references are modified in the receiver to reflect the new child. The lastChild of the receiver is set to the child, and the firstChild is set also if child is the first (or only) child. getException public Throwable getException()(Code) Returns the exception that occurred as a result of evaluating the Evaluation, or null if no exception occurred. getFirstChild public Evaluation getFirstChild()(Code) Returns the first child of this evaluation. Returns null if there are no children. getFirstDescendant public Evaluation getFirstDescendant()(Code) Gets the first descendent. In any Evaluation tree this will the Evaluation that was first executed. getLastChild public Evaluation getLastChild()(Code) Returns the last child of this evaluation. Returns null if there are no children. getLastDescendant public Evaluation getLastDescendant()(Code) Gets the last descendent. In any Evaluation tree this will the Evaluation that was most recently executing. getNext public Evaluation getNext()(Code) Returns the next sibling of this evaluation. Returns null if this is the last in a chain of evaluations. getNode public SimpleNode getNode()(Code) Returns the SimpleNode for this Evaluation getParent public Evaluation getParent()(Code) Returns the parent evaluation of this evaluation. If this returns null then it is is the root evaluation of a tree. getPrevious public Evaluation getPrevious()(Code) Returns the previous sibling of this evaluation. Returns null if this is the first in a chain of evaluations. getResult public Object getResult()(Code) Returns the result of the Evaluation, or null if it was a set operation. getSource public Object getSource()(Code) Returns the source object on which this Evaluation operated. init public void init(SimpleNode node, Object source, boolean setOperation)(Code) Reinitializes this Evaluation to the parameters specified. isSetOperation public boolean isSetOperation()(Code) Returns true if this Evaluation represents a set operation. reset public void reset()(Code) Resets this Evaluation to the initial state. setException public void setException(Throwable value)(Code) Sets the exception that occurred as a result of evaluating the Evaluation. This method is normally only used interally and should not be set without knowledge of what you are doing. setNode public void setNode(SimpleNode value)(Code) Sets the node of the evaluation. Normally applications do not need to set this. Notable exceptions to this rule are custom evaluators that choose between navigable objects (as in a multi-root evaluator where the navigable node is chosen at runtime). setResult public void setResult(Object value)(Code) Sets the result of the Evaluation. This method is normally only used interally and should not be set without knowledge of what you are doing. setSetOperation public void setSetOperation(boolean value)(Code) Marks the Evaluation as a set operation if the value is true, else marks it as a get operation. setSource public void setSource(Object value)(Code) Sets the source of the evaluation. Normally applications do not need to set this. Notable exceptions to this rule are custom evaluators that choose between navigable objects (as in a multi-root evaluator where the navigable node is chosen at runtime). toString public String toString(boolean compact, boolean showChildren, String depth)(Code) Produces a String value for the Evaluation. If compact is true then a more compact form of the description only including the node type and unique identifier is shown, else a full description including source and result are shown. If showChildren is true the child evaluations are printed using the depth string given as a prefix. toString public String toString(boolean compact, String depth)(Code) Produces a String value for the Evaluation. If compact is true then a more compact form of the description only including the node type and unique identifier is shown, else a full description including source and result are shown. Child evaluations are printed using the depth string given as a prefix. toString public String toString()(Code) Returns a String description of the Evaluation.
