Method Summary

java.lang.Class	getType(ELContext context, java.lang.Object base, java.lang.Object property) For a given base and property, attempts to identify the most general type that is acceptable for an object to be passed as the value parameter in a future call to the ELResolver.setValue(oracle.adfnmc.el.ELContext, java.lang.Object, java.lang.Object, java.lang.Object) method.
java.lang.Object	getValue(ELContext context, java.lang.Object base, java.lang.Object property) Attempts to resolve the given property object on the given base object.
int	getVariableIndex()
boolean	isReadOnly(ELContext context, java.lang.Object base, java.lang.Object property) For a given base and property, attempts to determine whether a call to ELResolver.setValue(oracle.adfnmc.el.ELContext, java.lang.Object, java.lang.Object, java.lang.Object) will always fail.

getValue

public java.lang.Object getValue(ELContext context,
                                 java.lang.Object base,
                                 java.lang.Object property)

Description copied from interface: ELResolver

Attempts to resolve the given property object on the given base object.

If this resolver handles the given (base, property) pair, the propertyResolved property of the ELContext object must be set to true by the resolver, before returning. If this property is not true after this method is called, the caller should ignore the return value.

Specified by:

getValue in interface ELResolver

Parameters:

context - The context of this evaluation.

base - The base object whose property value is to be returned, or null to resolve a top-level variable.

property - The property or variable to be resolved.

Returns:

If the propertyResolved property of ELContext was set to true, then the result of the variable or property resolution; otherwise undefined.

getType

public java.lang.Class getType(ELContext context,
                               java.lang.Object base,
                               java.lang.Object property)

Description copied from interface: ELResolver

For a given base and property, attempts to identify the most general type that is acceptable for an object to be passed as the value parameter in a future call to the ELResolver.setValue(oracle.adfnmc.el.ELContext, java.lang.Object, java.lang.Object, java.lang.Object) method.

If this resolver handles the given (base, property) pair, the propertyResolved property of the ELContext object must be set to true by the resolver, before returning. If this property is not true after this method is called, the caller should ignore the return value.

This is not always the same as getValue().getClass(). For example, in the case of an ArrayELResolver, the getType method will return the element type of the array, which might be a superclass of the type of the actual element that is currently in the specified array element.

Specified by:

getType in interface ELResolver

Parameters:

context - The context of this evaluation.

base - The base object whose property value is to be analyzed, or null to analyze a top-level variable.

property - The property or variable to return the acceptable type for.

Returns:

If the propertyResolved property of ELContext was set to true, then the most general acceptable type; otherwise undefined.

setValue

public void setValue(ELContext context,
                     java.lang.Object base,
                     java.lang.Object property,
                     java.lang.Object value)

Description copied from interface: ELResolver

Attempts to set the value of the given property object on the given base object.

If this resolver handles the given (base, property) pair, the propertyResolved property of the ELContext object must be set to true by the resolver, before returning. If this property is not true after this method is called, the caller can safely assume no value has been set.

Specified by:

setValue in interface ELResolver

Parameters:

context - The context of this evaluation.

base - The base object whose property value is to be set, or null to set a top-level variable.

property - The property or variable to be set.

value - The value to set the property or variable to.

isReadOnly

public boolean isReadOnly(ELContext context,
                          java.lang.Object base,
                          java.lang.Object property)

Description copied from interface: ELResolver

For a given base and property, attempts to determine whether a call to ELResolver.setValue(oracle.adfnmc.el.ELContext, java.lang.Object, java.lang.Object, java.lang.Object) will always fail.

If this resolver handles the given (base, property) pair, the propertyResolved property of the ELContext object must be set to true by the resolver, before returning. If this property is not true after this method is called, the caller should ignore the return value.

Specified by:

isReadOnly in interface ELResolver

Parameters:

context - The context of this evaluation.

base - The base object whose property value is to be analyzed, or null to analyze a top-level variable.

property - The property or variable to return the read-only status for.

Returns:

If the propertyResolved property of ELContext was set to true, then true if the property is read-only or false if not; otherwise undefined.
