public URLInputNode()

Method Detail

getWorkerClassName

public String getWorkerClassName()

Description copied from class: Node

Return the node's associated com.levigo.jadice.server.core.NodeWorker full qualified class's name. By default, the worker class name is

• The same as the node name with the trailing "Node" replaced by "Worker" if the node name ends in "Node"
• The node class name with an appended "Worker" otherwise.

The package name of the worker class is the name of the Node's package with an appended ".worker".

This behavior can be overridden in concrete subclasses.

Overrides:

getWorkerClassName in class Node

Returns:

the full qualified class name of the worker of this node.

setURLs

public void setURLs(List<URL> urls)

Specify the resources to download.

Parameters:

urls - the resources to download.

getURLs

public List<URL> getURLs()

isAllowRelativeResources

public boolean isAllowRelativeResources()

Returns:

true if and only if linked resourced are allowed to be resolved.

setAllowRelativeResources

public void setAllowRelativeResources(boolean allowResources)

Allow or deny the retrieval of resources that are relatively (or in the same domain) linked to the first downloaded resource. References that are linked absolutely must be allowed in subsequent processing nodes, e.g. via HTMLRendererNode.setAllowHTTPResources(boolean).

Default value: false

Parameters:

allowResources - true if and only if retrieval of hyperlinks is allowed

getInputCardinality

public Node.Cardinality getInputCardinality()

Description copied from class: Node

Return the input cardinality of this node, i.e. how many bundles (not streams!) it expects to process. By default, nodes are "pipe-style", i.e. one input, one output.

Overrides:

getInputCardinality in class Node

Returns:

input cardinality
