org.apache.jackrabbit.oak.spi.security.ConfigurationParameters

All Implemented Interfaces:

Map<String,Object>

public final class ConfigurationParameters
extends Object
implements Map<String,Object>

ConfigurationParameters is a convenience class that allows typed access to configuration properties. It implements the Map interface but is immutable.

Method Summary

Modifier and Type	Method	Description
void	clear()
boolean	contains(@NotNull String key)	Returns true if this instance contains a configuration entry with the specified key irrespective of the defined value; false otherwise.
boolean	containsKey(Object key)
boolean	containsValue(Object value)
@NotNull Set<Map.Entry<String,Object>>	entrySet()
Object	get(Object key)
<T> T	getConfigValue(@NotNull String key, T defaultValue)	Returns the value of the configuration entry with the given key applying the following rules: If this instance doesn't contain a configuration entry with that key, or if the entry is null, the specified defaultValue will be returned. If the configured value is not null an attempt is made to convert the configured value to match the type of the default value.
<T> T	getConfigValue(@NotNull String key, T defaultValue, @Nullable Class<T> targetClass)	Returns the value of the configuration entry with the given key applying the following rules: If this instance doesn't contain a configuration entry with that key the specified defaultValue will be returned. If defaultValue is null the original value will be returned. If the configured value is null this method will always return null. If neither defaultValue nor the configured value is null an attempt is made to convert the configured value to match the type of the default value.

Method Details

of

@NotNull
public static @NotNull ConfigurationParameters of(@NotNull
 @NotNull ConfigurationParameters... params)

Creates a new configuration parameters instance by merging all params sequentially. I.e. property define in subsequent arguments overwrite the ones before.

Parameters:

params - source parameters to merge

Returns:

merged configuration parameters or EMPTY if all source params were empty.

of

@NotNull
public static @NotNull ConfigurationParameters of(@NotNull
 @NotNull Properties properties)

Creates new a configuration parameters instance by copying the given properties.

Parameters:

properties - source properties

Returns:

configuration parameters or EMPTY if the source properties were empty.

of

@NotNull
public static @NotNull ConfigurationParameters of(@NotNull
 @NotNull Dictionary<String,Object> properties)

Creates new a configuration parameters instance by copying the given properties.

Parameters:

properties - source properties

Returns:

configuration parameters or EMPTY if the source properties were empty.

of

@NotNull
public static @NotNull ConfigurationParameters of(@NotNull
 @NotNull Map<?,?> map)

Creates new a configuration parameters instance by copying the given map.

Parameters:

map - source map

Returns:

configuration parameters or EMPTY if the source map was empty.

of

@NotNull
public static @NotNull ConfigurationParameters of(@NotNull
 @NotNull String key,
 @NotNull
 @NotNull Object value)

Creates new a single valued configuration parameters instance from the given key and value.

Parameters:

key - The key

value - The value

Returns:

a new instance of configuration parameters.

of

@NotNull
public static @NotNull ConfigurationParameters of(@NotNull
 @NotNull String key1,
 @NotNull
 @NotNull Object value1,
 @NotNull
 @NotNull String key2,
 @NotNull
 @NotNull Object value2)

Creates new a configuration parameters instance from the given key and value pairs.

Parameters:

key1 - The key of the first pair.

value1 - The value of the first pair

key2 - The key of the second pair.

value2 - The value of the second pair.

Returns:

a new instance of configuration parameters.

contains

public boolean contains(@NotNull
 @NotNull String key)

Returns true if this instance contains a configuration entry with the specified key irrespective of the defined value; false otherwise.

Parameters:

key - The key to be tested.

Returns:

true if this instance contains a configuration entry with the specified key irrespective of the defined value; false otherwise.

getConfigValue

@Nullable
public <T> T getConfigValue(@NotNull
 @NotNull String key,
 @Nullable
 T defaultValue,
 @Nullable
 @Nullable Class<T> targetClass)

Returns the value of the configuration entry with the given key applying the following rules:

• If this instance doesn't contain a configuration entry with that key the specified defaultValue will be returned.
• If defaultValue is null the original value will be returned.
• If the configured value is null this method will always return null.
• If neither defaultValue nor the configured value is null an attempt is made to convert the configured value to match the type of the default value.

Parameters:

key - The name of the configuration option.

defaultValue - The default value to return if no such entry exists or to use for conversion.

targetClass - The target class

Returns:

The original or converted configuration value or null.

getConfigValue

@NotNull
public <T> T getConfigValue(@NotNull
 @NotNull String key,
 @NotNull
 T defaultValue)

Returns the value of the configuration entry with the given key applying the following rules:

• If this instance doesn't contain a configuration entry with that key, or if the entry is null, the specified defaultValue will be returned.
• If the configured value is not null an attempt is made to convert the configured value to match the type of the default value.

Parameters:

key - The name of the configuration option.

defaultValue - The default value to return if no such entry exists or to use for conversion.

Returns:

The original or converted configuration value or defaultValue if no entry for the given key exists.
