Package com.yahoo.processing.request.properties

Class PropertyMap

java.lang.Object

com.yahoo.processing.request.Properties

com.yahoo.processing.request.properties.PropertyMap

All Implemented Interfaces:

Cloneable

public class PropertyMap
extends Properties

A HashMap backing of Properties.

When this is cloned it will deep copy not only the model object map, but also each clonable member inside the map.

Subclassing is supported, a hook can be implemented to provide conditional inclusion in the map. By default - all properties are accepted, so set is never propagated.

This class is not multithread safe.

Method Summary

Modifier and Type	Method	Description
PropertyMap	clone()	Clones this instance and recursively all chained instance.
Object	get(CompoundName name, Map<String,String> context, Properties substitution)	Gets a named value which (if necessary) is resolved using a property context.
Map<String,Object>	listProperties(CompoundName path, Map<String,String> context, Properties substitution)	Returns a snapshot of all properties of this having a given path prefix Some sources of properties may not be list-able and will not be included in this snapshot.
void	set(CompoundName name, Object value, Map<String,String> context)	Sets a value to the first chained instance which accepts it.
protected boolean	shouldSet(CompoundName name, Object value)	Return true if this value should be set in this map, false if the set should be propagated instead This default implementation always returns true.

Method Details

set

public void set(CompoundName name,
 Object value,
 Map<String,String> context)

Description copied from class: Properties

Sets a value to the first chained instance which accepts it. This default implementation forwards to the chained instance or throws a RuntimeException if there is not chained instance.

Overrides:

set in class Properties

Parameters:

name - the name of the property

value - the value to set. Setting a property to null clears it.

context - the context used to resolve where the values should be set, or null if none

shouldSet

protected boolean shouldSet(CompoundName name,
 Object value)

Return true if this value should be set in this map, false if the set should be propagated instead This default implementation always returns true.

get

public Object get(CompoundName name,
 Map<String,String> context,
 Properties substitution)

Description copied from class: Properties

Gets a named value which (if necessary) is resolved using a property context.

Overrides:

get in class Properties

Parameters:

name - the name of the property to return

context - the variant resolution context, or null if none

substitution - the properties used to substitute in these properties, or null if none

clone

public PropertyMap clone()

Description copied from class: Properties

Clones this instance and recursively all chained instance. Implementations should call this and clone their own state as appropriate

Overrides:

clone in class Properties

listProperties

public Map<String,Object> listProperties(CompoundName path,
 Map<String,String> context,
 Properties substitution)

Description copied from class: Properties

Returns a snapshot of all properties of this having a given path prefix Some sources of properties may not be list-able and will not be included in this snapshot.

Overrides:

listProperties in class Properties

Parameters:

path - the prefix (up to a ".") of the properties to return, or null or the empty string to return all properties

context - the context used to resolve the properties, or null if none

substitution - the properties which will be used to do string substitution in the values added to the map
