Modifier and Type	Method	Description
protected abstract T	getPatternConfiguration(String key, String value, Map<String,String> confMap)	Returns the ConfigureableField holding the parsed configuration for every configured key.
protected abstract BiConsumer<T,Object>	getProcessConsumer(Document sourceDocument, boolean visible)	Returns a BiConsumer whose input is the configured ConfigureableField with the value of the currently processed record.
void	initialize(FieldConfigAccess fieldConfig, Map<String,String> confMap)	DataPreProcessor MUST have a no-args constructor.
protected boolean	isRecordVisible(Document sourceDocument, boolean visible)	Called at the end of each process(Document, boolean) run after getProcessConsumer(Document, boolean) is has run for every ConfigureableField, to determine weather the record should be visible or not.
boolean	process(Document sourceDocument, boolean visible)	Called for each source document.

Method Detail

initialize

public void initialize(FieldConfigAccess fieldConfig,
                       Map<String,String> confMap)

Description copied from interface: DocumentPreProcessor

DataPreProcessor MUST have a no-args constructor. To configure it afterwards, this method will be used.

Specified by:

initialize in interface DocumentPreProcessor

confMap - custom string-to-string map that can be configured per DocumentPreProcessor.

getPatternConfiguration

protected abstract T getPatternConfiguration(String key,
                                             String value,
                                             Map<String,String> confMap)

Returns the ConfigureableField holding the parsed configuration for every configured key.

Parameters:

key - a key from the data processor configuration for this data processor.

value - the value of that key.

confMap - the complete data processor configuration map.

Returns:

the parsed configurable field for the key.

process

public boolean process(Document sourceDocument,
                       boolean visible)

Description copied from interface: DocumentPreProcessor

Called for each source document.

Specified by:

process in interface DocumentPreProcessor

visible - weather or not the record is currently marked for indexing.

Returns:

true if the record should be indexed, false otherwise.

getProcessConsumer

protected abstract BiConsumer<T,Object> getProcessConsumer(Document sourceDocument,
                                                                 boolean visible)

Returns a BiConsumer whose input is the configured ConfigureableField with the value of the currently processed record. The consumer gets called in the DocumentPreProcessor.process(Document, boolean) method for each configured key.

Parameters:

sourceDocument - the record data

visible - the current visibility of the record

Returns:

a BiConsumer whose accept method should handle every PatternConfiguration with the corresponding value.

isRecordVisible

protected boolean isRecordVisible(Document sourceDocument,
                                  boolean visible)

Called at the end of each process(Document, boolean) run after getProcessConsumer(Document, boolean) is has run for every ConfigureableField, to determine weather the record should be visible or not.

Parameters:

sourceDocument - the record data

visible - the current visibility of the record

Returns:

true if the record should be indexed, false otherwise.
