Modifier and Type

Method

Description

String

getCoreExpression()

Get the core expression to execute first before any return foo logic is started.

Class

getGetterClass()

The type returned from the expression - if any.

String

getLastExpression()

Gets the last expression to be pre-pended with a return <expression> block.

Class

getSetterClass()

The type used to set the value - if any.

protected Object

getValueBody(OgnlContext context, Object source)

Subclasses implement this method to do the actual work of extracting the appropriate value from the source object.

protected void

setValueBody(OgnlContext context, Object target, Object value)

Subclasses implement this method to do the actual work of setting the appropriate value in the target object.

String

toGetSourceString(OgnlContext context, Object target)

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.

String

toSetSourceString(OgnlContext context, Object target)

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.

Method Details
- 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

  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;
- toString
  
  public String toString()
  
  Overrides:

  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.

  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:
