Class PathBasedFilterInvocationDefinitionMap

java.lang.Object
  org.acegisecurity.intercept.web.AbstractFilterInvocationDefinitionSource
      org.acegisecurity.intercept.web.PathBasedFilterInvocationDefinitionMap

All Implemented Interfaces:

ObjectDefinitionSource, FilterInvocationDefinitionMap, FilterInvocationDefinitionSource

public class PathBasedFilterInvocationDefinitionMap
extends AbstractFilterInvocationDefinitionSource
implements FilterInvocationDefinitionMap

Maintains a List of ConfigAttributeDefinitions associated with different HTTP request URL Apache Ant path-based patterns.

Apache Ant path expressions are used to match a HTTP request URL against a ConfigAttributeDefinition.

The order of registering the Ant paths using the addSecureUrl(String, ConfigAttributeDefinition) is very important. The system will identify the first matching path for a given HTTP URL. It will not proceed to evaluate later paths if a match has already been found. Accordingly, the most specific paths should be registered first, with the most general paths registered last.

If no registered paths match the HTTP URL, null is returned.

Method Detail

getConfigAttributeDefinitions

public Iterator getConfigAttributeDefinitions()

Description copied from interface: ObjectDefinitionSource

If available, all of the ConfigAttributeDefinitions defined by the implementing class.

This is used by the AbstractSecurityInterceptor to perform startup time validation of each ConfigAttribute configured against it.

Specified by:

getConfigAttributeDefinitions in interface ObjectDefinitionSource

Returns:

an iterator over all the ConfigAttributeDefinitions or null if unsupported

setConvertUrlToLowercaseBeforeComparison

public void setConvertUrlToLowercaseBeforeComparison(boolean convertUrlToLowercaseBeforeComparison)

Specified by:

setConvertUrlToLowercaseBeforeComparison in interface FilterInvocationDefinitionMap

isConvertUrlToLowercaseBeforeComparison

public boolean isConvertUrlToLowercaseBeforeComparison()

getMapSize

public int getMapSize()

addSecureUrl

public void addSecureUrl(String antPath,
                         ConfigAttributeDefinition attr)

Specified by:

addSecureUrl in interface FilterInvocationDefinitionMap

lookupAttributes

public ConfigAttributeDefinition lookupAttributes(String url)

Description copied from class: AbstractFilterInvocationDefinitionSource

Performs the actual lookup of the relevant ConfigAttributeDefinition for the specified FilterInvocation.

Provided so subclasses need only to provide one basic method to properly interface with the FilterInvocationDefinitionSource.

Public visiblity so that tablibs or other view helper classes can access the ConfigAttributeDefinition applying to a given URI pattern without needing to construct a mock FilterInvocation and retrieving the attibutes via the AbstractFilterInvocationDefinitionSource.getAttributes(Object) method.

Specified by:

lookupAttributes in class AbstractFilterInvocationDefinitionSource

Parameters:

url - the URI to retrieve configuration attributes for

Returns:

the ConfigAttributeDefinition that applies to the specified FilterInvocation
