    • getIndexedPropertyType

      public int getIndexedPropertyType(OgnlContext context, Object source) throws OgnlException
      Returns true if this property is described by an IndexedPropertyDescriptor and that if followed by an index specifier it will call the index get/set methods rather than go through property accessors.
      Parameters:
      context - The context
      source - The object source
      Returns:
      true, if this property is described by an IndexedPropertyDescriptor
      Throws:
      OgnlException - if an error occurs
    • getProperty

      public Object getProperty(OgnlContext context, Object source) throws OgnlException
      Throws:
      OgnlException
    • 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
    • isNodeSimpleProperty

      public boolean isNodeSimpleProperty(OgnlContext context) throws OgnlException
      Overrides:
      isNodeSimpleProperty 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.
    • 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.
    • getTarget

      Object getTarget(OgnlContext context, Object target, String name) throws OgnlException
      Throws:
      OgnlException
    • getIndexedWriteMethod

      Method getIndexedWriteMethod(PropertyDescriptor pd)
    • 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:
      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.
