All Implemented Interfaces:

Configurable, Disposable, org.apache.cocoon.components.modules.input.InputModule, Serviceable

public class StringConcatMetaModule

extends org.apache.cocoon.components.modules.input.AbstractMetaModule

StringConcatMetaModule concats strings from configured module chain. It assumes that all modules have string attributes, on the contrary, it calls toString() method.
If null is returned by some module RuntimeException will be thrown.

For configuration of input module chain take a look at example on ChainMetaModule.

Method Detail

getFilteredInputModules

protected org.apache.cocoon.components.modules.input.ModuleHolder[] getFilteredInputModules(Configuration[] configurations)
                                                                                     throws ConfigurationException

Parameters:

configurations - List of configuration objects for input modules

Returns:

List of ModuleHolder objects obtained from configurations. If configuration does not have attribute it will be skipped and error logged.

Throws:

ConfigurationException

getInputModules

protected org.apache.cocoon.components.modules.input.ModuleHolder[] getInputModules(Configuration[] dynamicConfigurations)
                                                                             throws ConfigurationException

Parameters:

dynamicConfigurations -

Returns:

It returns list of modules. If does not contain valid list of configuration (e.g. is null) then static list is returned. In other case list is obtained from dynamicConfigurations.

Throws:

ConfigurationException

configure

public void configure(Configuration config)
               throws ConfigurationException

Throws:

ConfigurationException

                           Configuration modeConf,
                           Map objectModel)
                    throws ConfigurationException

Throws:
