Modifier and Type

Method

Description

Class

getGetterClass()

The type returned from the expression - if any.

int

getIndexedPropertyType(OgnlContext context, Object source)

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.

Object

getProperty(OgnlContext context, Object source)

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.

boolean

isIndexedAccess()

Returns true if this property is itself an index reference.

boolean

isNodeSimpleProperty(OgnlContext context)

void

setIndexedAccess(boolean value)

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
- setIndexedAccess
  
  public void setIndexedAccess(boolean value)
- isIndexedAccess
  
  public boolean isIndexedAccess()
  
  Returns true if this property is itself an index reference.
- 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.
  
  Throws:
  
  OgnlException
- 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.

  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.

  Specified by:
  
  toSetSourceString in interface JavaSource
  
  Overrides:
  
  toSetSourceString in class SimpleNode
  
  Returns:
  
  Literal java string representation of an object get.
