Constructs a default factory.

Method Detail

newInstance

public MetadataEnvironment newInstance(java.util.Map<java.lang.String,java.lang.Object> config)

Description copied from class: MetadataEnvironmentFactory

Creates a new instance of MetadataEnvironment based on the current user context and the configuration.

Specified by:

newInstance in class MetadataEnvironmentFactory

Parameters:

config - the configuration of the new instance; null if the default configuration should be used

Returns:

a new instance of MetadataEnvironment based on the current user context and the configuration if supplied

isCustomMetadataEnvironment

public boolean isCustomMetadataEnvironment(MetadataEnvironment e)

Description copied from class: MetadataEnvironmentFactory

Returns true if the given instance is a custom instance. A custom instance is an instance that is not created by this factory.

Specified by:

isCustomMetadataEnvironment in class MetadataEnvironmentFactory

Parameters:

e - the instance to be checked

Returns:

true if the given instance is a custom instance

MetadataEnvironmentFactory.newInstance(java.util.Map<java.lang.String, java.lang.Object>)

supportsUnifiedEnvironments

protected boolean supportsUnifiedEnvironments()

Description copied from class: MetadataEnvironmentFactory

Returns true if the metadata environments created by this factory are unified environments.

A unified environment supports multiple repositories. A non-unified environment supports only one single MDS repository. By default this method returns true. The implementation may allow this method to return false in a system that is not ready to be transitioned into a unified environment but the new code is already in place.

Overrides:

supportsUnifiedEnvironments in class MetadataEnvironmentFactory

Returns:

true if the metadata environment is unified; false otherwise

configureCurrentADFSessionOptions

protected void configureCurrentADFSessionOptions(MetadataEnvironment env)

Overrides:

configureCurrentADFSessionOptions in class MetadataEnvironmentFactory

Parameters:

env - the MetadataEnvironment object according to which the current ADFSessionOptions should be configured

getContextParameter

protected java.lang.String getContextParameter(ADFContext context,
                                               java.lang.String name)

Description copied from class: MetadataEnvironmentFactory

Returns the value of a parameter of a context for this factory to create a new metadata environment. If the context is initialized in a servlet environment for a servlet request, this method returns the first value of the request parameter with a name that ends with the given name.

Overrides:

getContextParameter in class MetadataEnvironmentFactory

Parameters:

context - the context for this factory to create a new metadata environment

name - the name of the parameter

Returns:

the value of the context parameter; null if the value is null or the parameter does not exist
