public interface PropertyResolver

Indicates an entity that can be configured using properties. The properties are simple name-value pairs where the actual value type depends on the property. Some automatic conversions may be available - e.g., from a string to a numeric or boolean value, or from int to long, etc.. Note: implementations may decide to use case insensitive property names, therefore it is highly discouraged to use names that differ from each other only in case sensitivity. Also, implementations may choose to trim whitespaces, thus such are also highly discouraged.

Field Detail

EMPTY

static final PropertyResolver EMPTY

An "empty" resolver with no properties and no parent

Method Detail

getParentPropertyResolver

PropertyResolver getParentPropertyResolver()

Returns:

The parent resolver that can be used to query for missing properties - null if no parent

getProperties

Map<String,Object> getProperties()

A map of properties that can be used to configure the SSH server or client. This map will never be changed by either the server or client and is not supposed to be changed at runtime (changes are not bound to have any effect on a running client or server), though it may affect the creation of sessions later as these values are usually not cached.

Note: the type of the mapped property should match the expected configuration value type - Long, Integer, Boolean, String, etc.... If it doesn't, the toString() result of the mapped value is used to convert it to the required type. E.g., if the mapped value is the string "1234" and the expected value is a long then it will be parsed into one. Also, if the mapped value is an Integer but a long is expected, then it will be converted into one.

Returns:

a valid Map containing configuration values, never null. Note: may be immutable.
