Class DefaultHeadersMapFactory

java.lang.Object

org.apache.camel.impl.DefaultHeadersMapFactory

All Implemented Interfaces:

HeadersMapFactory

public class DefaultHeadersMapFactory
extends Object
implements HeadersMapFactory

Default HeadersMapFactory which uses the CaseInsensitiveMap. This implementation uses a CaseInsensitiveMap storing the headers. This allows us to be able to lookup headers using case insensitive keys, making it easier for end users as they do not have to be worried about using exact keys. See more details at CaseInsensitiveMap.

public DefaultHeadersMapFactory()

Method Detail

newMap

public Map<String,Object> newMap()

Description copied from interface: HeadersMapFactory

Creates a new empty Map

Specified by:

newMap in interface HeadersMapFactory

Returns:

new empty map

newMap

public Map<String,Object> newMap(Map<String,Object> map)

Description copied from interface: HeadersMapFactory

Creates a new Map and copies over all the content from the existing map.

The copy of the content should use defensive copy, so the returned map can add/remove/change the content without affecting the existing map.

Specified by:

newMap in interface HeadersMapFactory

Parameters:

map - existing map to copy over (must use defensive copy)

Returns:

new map with the content from the existing map

isInstanceOf

public boolean isInstanceOf(Map<String,Object> map)

Description copied from interface: HeadersMapFactory

Whether the given Map implementation is created by this factory?

Specified by:

isInstanceOf in interface HeadersMapFactory

Returns:

true if created from this factory, false if not

isCaseInsensitive

public boolean isCaseInsensitive()

Description copied from interface: HeadersMapFactory

Whether the created Map are case insensitive or not.

Important: When using case sensitive (this method return false). Then the map is case sensitive which means headers such as content-type and Content-Type are two different keys which can be a problem for some protocols such as HTTP based, which rely on case insensitive headers. However case sensitive implementations can yield faster performance. Therefore use case sensitive implementation with care.
