Method Detail

createTransport

public ILcdTransport createTransport()

Creates a new transport based on Apache's HttpClient library 4.5.2.

Specified by:

createTransport in interface ILcdTransportFactory

Returns:

a new transport, never null

isCaching

public boolean isCaching()

Tells whether or not HTTP caching is enabled for transports created by this factory. When enabled, HTTP requests are cached. Default is disabled.

Returns:

true if caching is enabled, false otherwise

See Also:

setCaching(boolean), getMaxCacheEntries()

setCaching

public void setCaching(boolean aOn)

Enables or disables caching for transports created by this factory. Default is disabled.

Parameters:

aOn - when true, transports created by this factory will cache HTTP requests

See Also:

isCaching(), setMaxCacheEntries(int)

getMaxCacheEntries

public int getMaxCacheEntries()

Returns the maximum number of cache entries for transports created by this factory. Sane values should be positive, but this factory does not enforce this. Default is 1000.

Returns:

the maximum number of cache entries in the HTTP cache

See Also:

setMaxCacheEntries(int), setCaching(boolean)

setMaxCacheEntries

public void setMaxCacheEntries(int aMaxCacheEntries)

Setter for the maximum number of cache entries used by transports created by this factory. For the purpose of BingMaps imagery, the objects that will be cached will be compressed (JPEG) Bing tiles.

Default value is 1000.

Parameters:

aMaxCacheEntries - the maximum number of cache entries.

See Also:

getMaxCacheEntries(), setCaching(boolean)

getMaxConnectionsPerRoute

public int getMaxConnectionsPerRoute()

Gets the maximum number of connections per route. The default is 2. Negative values mean that the implementation's default will be used.

Returns:

maximum number of connections per route

setMaxConnectionsPerRoute

public void setMaxConnectionsPerRoute(int aMaxConnectionsPerRoute)

Sets the maximum number of connections per route. The default value is 2. Negative values mean that the implementation's default will be used.

Parameters:

aMaxConnectionsPerRoute - the maximum number of connections per route

getMaxTotalConnections

public int getMaxTotalConnections()

Gets the maximum number of total connections. The default is 20. Negative values mean that the implementation's default will be used.

Returns:

the maximum number of total connections

setMaxTotalConnections

public void setMaxTotalConnections(int aMaxTotalConnections)

Sets the maximum number of total connections. The default is 20. Negative values mean that the implementation's default will be used.

Parameters:

aMaxTotalConnections - the maximum number of total connections

createTransport

public ILcdTransport createTransport(Object aConfiguration)

Creates a transport using Apache's HttpClient 4.5.2, with a transport configuration of type HttpClient.

The transport configuration should have been created by an earlier call to createConfiguration().

Parameters:

aConfiguration - a transport configuration, which must be of type HttpClient

Returns:

a transport

Throws:

IllegalArgumentException - if the transport configuration is incompatible with the transports created by this factory

createConfiguration

public Object createConfiguration()

Creates a valid transport configuration that can be used to create a transport. This factory creates transport configurations of type HttpClient.

To customize the configuration, cast the object to HttpClient and configure it accordingly.

In order to configure caching, you can use the methods setCaching(boolean) and setMaxCacheEntries(int) on this factory.

If you want to customize caching even further, you can also decorate the HttpClient configuration object with a CachingHttpClient yourself. If you do this, you should disable caching on this factory.

Returns:

a valid transport configuration of type HttpClient
