Method Summary

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.

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.

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.

ASTProperty

public ASTProperty(int id)

Method Details

setIndexedAccess

public void setIndexedAccess(boolean value)

isIndexedAccess

public boolean isIndexedAccess()

Returns true if this property is itself an index reference.

Returns:

true if this property is an index reference, false otherwise.

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 OgnlContext within which to perform the operation.

source - the Object (indexed property) from which to retrieve the indexed property type.

Returns:

the int representing the indexed property type of source.

Throws:

OgnlException - if source is not an indexed property.

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

Parameters:

context - the OgnlContext within which to perform the operation.

source - the Object from which to get the value body.

Returns:

the value body from the source (as appropriate within the provided context).

Throws:

OgnlException - if the value body get fails.

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

Parameters:

context - the OgnlContext within which to perform the operation.

target - the Object upon which to set the value body.

value - the Object representing the value body to apply to the target.

Throws:

OgnlException - if the value body set fails.

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.

toString

public String toString()

Overrides:

toString in class SimpleNode

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

Parameters:

context - the OgnlContext within which to perform the operation.

target - the Object from which to retrieve the get source string.

Returns:

Literal java string representation of an object get.

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:

toSetSourceString in interface JavaSource

Overrides:

toSetSourceString in class SimpleNode

Parameters:

context - the OgnlContext within which to perform the operation.

target - the Object from which to retrieve the set source string.

Returns:

Literal java string representation of an object set.
