    • getValueBody

      protected Object getValueBody(OgnlContext context, Object source) throws OgnlException
      Description copied from class: SimpleNode
      Subclasses implement this method to do the actual work of extracting the appropriate value from the source object.
      Specified by:
      getValueBody in class SimpleNode
      Throws:
      OgnlException
    • setValueBody

      protected void setValueBody(OgnlContext context, Object target, Object value) throws OgnlException
      Description copied from class: SimpleNode
      Subclasses implement this method to do the actual work of setting the appropriate value in the target object. The default implementation throws an InappropriateExpressionException, meaning that it cannot be a set expression.
      Overrides:
      setValueBody in class SimpleNode
      Throws:
      OgnlException
    • getGetterClass

      public Class getGetterClass()
      Description copied from interface: NodeType
      The type returned from the expression - if any.
      Specified by:
      getGetterClass in interface NodeType
      Returns:
      The type.
    • getSetterClass

      public Class getSetterClass()
      Description copied from interface: NodeType
      The type used to set the value - if any.
      Specified by:
      getSetterClass in interface NodeType
      Returns:
      The type.
    • getCoreExpression

      public String getCoreExpression()
      Description copied from interface: OrderedReturn
      Get the core expression to execute first before any return foo logic is started.
      Specified by:
      getCoreExpression in interface OrderedReturn
      Returns:
      The core standalone expression that shouldn't be pre-pended with a return keyword.
    • getLastExpression

      public String getLastExpression()
      Description copied from interface: OrderedReturn
      Gets the last expression to be pre-pended with a return <expression> block.
      Specified by:
      getLastExpression in interface OrderedReturn
      Returns:
      The expression representing the return portion of a statement;
    • toGetSourceString

      public String toGetSourceString(OgnlContext context, Object target)
      Description copied from interface: JavaSource
      Expected to return a java source representation of itself such that it could be turned into a literal java expression to be compiled and executed for ExpressionAccessor.get(OgnlContext, Object) calls.
      Specified by:
      toGetSourceString in interface JavaSource
      Overrides:
      toGetSourceString in class SimpleNode
      Returns:
      Literal java string representation of an object get.
    • toSetSourceString

      public String toSetSourceString(OgnlContext context, Object target)
      Description copied from interface: JavaSource
      Expected to return a java source representation of itself such that it could be turned into a literal java expression to be compiled and executed for ExpressionAccessor.get(OgnlContext, Object) calls.
      Specified by:
      toSetSourceString in interface JavaSource
      Overrides:
      toSetSourceString in class SimpleNode
      Returns:
      Literal java string representation of an object get.
    • accept

      public <R, P> R accept(NodeVisitor<? extends R,? super P> visitor, P data) throws OgnlException
      Description copied from interface: Node
      Supports the Visitor pattern. The method which corresponds to the runtime type of this Node will be called.
      Specified by:
      accept in interface Node
      Type Parameters:
      R - The return type of the visitor.visit method.
      P - The type of the second parameter type.
      Parameters:
      visitor - The visitor to accept.
      data - The second parameter to pass through to visitor.visit
      Returns:
      the value returned by visitor.visit
      Throws:
      OgnlException
