Interface ConfigurationParameterDeclarations

All Superinterfaces:

Cloneable, MetaDataObject, Serializable, XMLizable

public interface ConfigurationParameterDeclarations
extends MetaDataObject

The declarations of configuration parameters in a Resource. A Resource can either declare a single list of ConfigurationParameters or a list of ConfigurationGroups, where each group can contain a list of parameters. When groups are used, the Resource can also declare a list of common parameters shared by all groups.

Field Summary

Modifier and Type	Field and Description
static String	SEARCH_STRATEGY_DEFAULT_FALLBACK A value for the searchStrategy property indicating that if there is no value declared in a group, look in the default group.
static String	SEARCH_STRATEGY_LANGUAGE_FALLBACK A value for the searchStrategy property that is useful when ISO language and country codes are used as configuration group names.

Field Detail

SEARCH_STRATEGY_NONE

static final String SEARCH_STRATEGY_NONE

A value for the searchStrategy property indicating that there is no fallback. If a request is made for the value of a parameter in a group and there is no such value in that exact group, null will be returned.

Constant Field Values

SEARCH_STRATEGY_DEFAULT_FALLBACK

static final String SEARCH_STRATEGY_DEFAULT_FALLBACK

A value for the searchStrategy property indicating that if there is no value declared in a group, look in the default group.

See Also:

Constant Field Values

SEARCH_STRATEGY_LANGUAGE_FALLBACK

static final String SEARCH_STRATEGY_LANGUAGE_FALLBACK

A value for the searchStrategy property that is useful when ISO language and country codes are used as configuration group names. If there is no value declared in a group, look in more general groups. The fallback sequence is lang-country-region -%gt; lang-country -%gt; lang -%gt; default. For example, if a request is made for the value of a parameter in the "en-GB" group and no such group exists, the value from the "en" group will be used instead.

Method Detail

getConfigurationParameters

ConfigurationParameter[] getConfigurationParameters()

Gets the configuration parameters for this Resource. This gets configuration parameters that are not defined within a group - see also getConfigurationGroups().

Returns:

an array containing ConfigurationParameter objects, each of which describes a configuration parameter for this Resource.

setConfigurationParameters

void setConfigurationParameters(ConfigurationParameter[] aParams)

Sets the configuration parameters for this Resource. This sets the configuration parameters that are not defined within groups - see also setConfigurationGroups(ConfigurationGroup[]).

Parameters:

aParams - an array containing ConfigurationParameter objects, each of which describes a configuration parameter for this Resource.

Throws:

UIMA_UnsupportedOperationException - if this object is not modifiable

addConfigurationParameter

void addConfigurationParameter(ConfigurationParameter aConfigurationParameter)

Adds a Configuration Parameter that is not in any group.

Parameters:

aConfigurationParameter - the Configuration Parameter to add

Throws:

UIMA_UnsupportedOperationException - if this object is not modifiable

removeConfigurationParameter

void removeConfigurationParameter(ConfigurationParameter aConfigurationParameter)

Removes an Configuration Parameter that is not in any group.

Parameters:

aConfigurationParameter - the Configuration Parameter to remove (must be == with an ConfigurationParameter in this collection, or this method will do nothing).

Throws:

UIMA_UnsupportedOperationException - if this object is not modifiable

getConfigurationGroups

ConfigurationGroup[] getConfigurationGroups()

Gets the configuration parameter groups for this Resource.

Returns:

an array containing ConfigurationGroup objects, each of which describes a configuration parameter group for this Resource.

setConfigurationGroups

void setConfigurationGroups(ConfigurationGroup[] aGroups)

Sets the configuration parameter groups for this Resource.

Parameters:

aGroups - an array containing ConfigurationGroup objects, each of which describes a configuration parameter group for this Resource.

Throws:

UIMA_UnsupportedOperationException - if this object is not modifiable

addConfigurationGroup

void addConfigurationGroup(ConfigurationGroup aConfigurationGroup)

Adds a Configuration Group.

Parameters:

aConfigurationGroup - the Configuration Group to add

Throws:

UIMA_UnsupportedOperationException - if this object is not modifiable

removeConfigurationGroup

void removeConfigurationGroup(ConfigurationGroup aConfigurationGroup)

Removes an Configuration Group

Parameters:

aConfigurationGroup - the Configuration Group to remove (must be == with an ConfigurationGroup defined on this resource, or this method will do nothing).

Throws:

UIMA_UnsupportedOperationException - if this object is not modifiable

getCommonParameters

ConfigurationParameter[] getCommonParameters()

Gets the configuration parameters that are common to all groups. This property is only meaningful if at least one group is defined.

Returns:

an array containing ConfigurationParameter objects, each of which describes a parameter common to all groups.

setCommonParameters

void setCommonParameters(ConfigurationParameter[] aParams)

Sets the configuration parameters that are common to all groups. This property is only meaningful if at least one group is defined.

Parameters:

aParams - an array containing ConfigurationParameter objects, each of which describes a parameter common to all groups.

addCommonParameter

void addCommonParameter(ConfigurationParameter aConfigurationParameter)

Adds a Configuration Parameter that is common to all groups.

Parameters:

aConfigurationParameter - the Configuration Parameter to add

Throws:

UIMA_UnsupportedOperationException - if this object is not modifiable

removeCommonParameter

void removeCommonParameter(ConfigurationParameter aConfigurationParameter)

Removes an Configuration Parameter that is common to all groups.

Parameters:

aConfigurationParameter - the Configuration Parameter to remove (must be == with an ConfigurationParameter in this collection, or this method will do nothing).

Throws:

UIMA_UnsupportedOperationException - if this object is not modifiable

getDefaultGroupName

String getDefaultGroupName()

Gets the name of the default configuration group. This must refer to the names of the configuration groups.

Returns:

the name of the default configuration group

setDefaultGroupName

void setDefaultGroupName(String aGroupName)

Sets the name of the default configuration group. This must refer to the names of the configuration groups.

Parameters:

aGroupName - the name of the default configuration group

getSearchStrategy

String getSearchStrategy()

Gets the configuration parameter search strategy. Valid values for this property are defined by constants on this interface.

Returns:

the configuration parameter search strategy

setSearchStrategy

void setSearchStrategy(String aStrategy)

Sets the configuration parameter search strategy. Valid values for this property are defined by constants on this interface.

Parameters:

aStrategy - the configuration parameter search strategy

getConfigurationParameter

ConfigurationParameter getConfigurationParameter(String aGroupName,
                                                 String aParamName)

Gets a configuration parameter.

Parameters:

aGroupName - the name of a group, or null for no group

aParamName - the name of the parameter

Returns:

the specified parameter, null if it does not exist

getConfigurationGroupDeclarations

ConfigurationGroup[] getConfigurationGroupDeclarations(String aGroupName)

Gets the declarations of a named configuration group. There may be more than one declaration for a single group name; in this case, all parameters contained in each of these declarations are considered part of the named group.

Parameters:

aGroupName - the name of a group

Returns:

an array of ConfigurationGroup declarations having the name aGroupName. If there are no such groups, an empty array is returned.
