### Constructor Detail

#### DefaultedHttpParams

    public DefaultedHttpParams(HttpParams local,
                       HttpParams defaults)

Deprecated.
Create the defaulted set of HttpParams.

Parameters:
  `local` - the mutable set of HttpParams
  `defaults` - the default set of HttpParams, not mutated by this class

### Method Detail

#### copy

    public HttpParams copy()

Deprecated.
Creates a copy of the local collection with the same default

Returns:
  a new set of parameters holding the same values as this one

#### getParameter

    public Object getParameter(String name)

Deprecated.
Retrieves the value of the parameter from the local collection and, if the parameter is not set locally, delegates its resolution to the default collection.

Parameters:
  `name` - the parent name.
Returns:
  an object that represents the value of the parameter, `null` if the parameter is not set or if it is explicitly set to `null`
See Also:
  `HttpParams.setParameter(String, Object)`

#### removeParameter

    public boolean removeParameter(String name)

Deprecated.
Attempts to remove the parameter from the local collection. This method does not modify the default collection.

Parameters:
  `name` - parameter name
Returns:
  true if the parameter existed and has been removed, false else.

#### setParameter

    public HttpParams setParameter(String name,
                          Object value)

Deprecated.
Sets the parameter in the local collection. This method does not modify the default collection.

Parameters:
  `name` - parameter name
  `value` - parameter value

#### getDefaults

    public HttpParams getDefaults()

Deprecated.

Returns:
  the default HttpParams collection

#### getNames

    public Set<String> getNames()

Deprecated.
Returns the current set of names from both the local and default HttpParams instances. Changes to the underlying HttpParams intances are not reflected in the set - it is a snapshot.

Specified by:
  `getNames` in interface `HttpParamsNames`
Overrides:
  `getNames` in class `AbstractHttpParams`
Returns:
  the combined set of names, as a Set<String>
Throws:
  `UnsupportedOperationException` - if either the local or default HttpParams instances do not implement HttpParamsNames
Since:
  4.2

#### getDefaultNames

    public Set<String> getDefaultNames()

Deprecated.
Returns the current set of defaults names. Changes to the underlying HttpParams are not reflected in the set - it is a snapshot.

Returns:
  the names, as a Set<String>
Throws:
  `UnsupportedOperationException` - if the default HttpParams instance does not implement HttpParamsNames
Since:
  4.2

#### getLocalNames

    public Set<String> getLocalNames()

Deprecated.
Returns the current set of local names. Changes to the underlying HttpParams are not reflected in the set - it is a snapshot.

Returns:
  the names, as a Set<String>
Throws:
  `UnsupportedOperationException` - if the local HttpParams instance does not implement HttpParamsNames
Since:
