Nested Class Summary

static interface

RuntimeApacheConfiguration.NodeVisitor<T> This is a node visitor interface to be implemented by the users of the RuntimeApacheConfiguration#walkRuntimeConfig(ApacheAugeasTree, ProcessInfo, ApacheBinaryInfo, Map) or RuntimeApacheConfiguration#walkRuntimeConfig(ApacheDirectiveTree, ProcessInfo, ApacheBinaryInfo, Map) methods.

Method Summary

static ApacheDirectiveTree	extract(ApacheDirectiveTree tree, ProcessInfo httpdProcessInfo, ApacheBinaryInfo httpdBinaryInfo, Map<String,String> moduleNames, boolean suppressUnknownModuleWarnings) Given the apache configuration and information about the parameters httpd was executed with this method provides the directive tree that corresponds to the actual runtime configuration as used by httpd.
static void	walkRuntimeConfig(RuntimeApacheConfiguration.NodeVisitor<ApacheDirective> visitor, ApacheDirectiveTree tree, ProcessInfo httpdProcessInfo, ApacheBinaryInfo httpdBinaryInfo, Map<String,String> moduleNames, boolean suppressUnknownModuleWarnings)
static void	walkRuntimeConfig(RuntimeApacheConfiguration.NodeVisitor<AugeasNode> visitor, AugeasTree tree, ProcessInfo httpdProcessInfo, ApacheBinaryInfo httpdBinaryInfo, Map<String,String> moduleNames, boolean suppressUnknownModuleWarnings)

Method Detail

extract

public static ApacheDirectiveTree extract(ApacheDirectiveTree tree,
                                          ProcessInfo httpdProcessInfo,
                                          ApacheBinaryInfo httpdBinaryInfo,
                                          Map<String,String> moduleNames,
                                          boolean suppressUnknownModuleWarnings)

Given the apache configuration and information about the parameters httpd was executed with this method provides the directive tree that corresponds to the actual runtime configuration as used by httpd.

This enables us to see which directives are actually in effect as opposed to just declared.

Parameters:

tree -

httpdProcessInfo -

httpdBinaryInfo -

moduleNames - the mapping from the module filename to the module name (i.e. mapping from the name used in IfModule to the name used in LoadModule)

suppressUnknownModuleWarnings - true if the method should suppress logging the warnings about unknown modules

Returns:

a new directive tree that represents the runtime configuration
