Method Detail

build

public BatchProcess build(InputStream is,
                          Map<String,String> runtimeAttributes)
                   throws IOException

Builds a BatchProcess from runtime arguments and a input stream of a configuration file. With the exception of the QueueBuilder, the builders choose how to adjudicate between runtime arguments and the elements in the configuration file.

This does not close the InputStream!

Parameters:

is - inputStream

runtimeAttributes - incoming runtime attributes

Returns:

batch process

Throws:

IOException

build

public BatchProcess build(Node docElement,
                          Map<String,String> incomingRuntimeAttributes)

Builds a FileResourceBatchProcessor from runtime arguments and a document node of a configuration file. With the exception of the QueueBuilder, the builders choose how to adjudicate between runtime arguments and the elements in the configuration file.

Parameters:

docElement - document element of the xml config file

incomingRuntimeAttributes - runtime arguments

Returns:

FileResourceBatchProcessor

getNumConsumers

public static int getNumConsumers(Map<String,String> attrs)

numConsumers is needed by both the crawler and the consumers. This utility method is to be used to extract the number of consumers from a map of String key value pairs.

If the value is "default", not a parseable integer or has a value < 1, then AbstractConsumersBuilder's getDefaultNumConsumers()

Parameters:

attrs - attributes from which to select the NUM_CONSUMERS_KEY

Returns:

number of consumers
