Class BeforeAfterAction

java.lang.Object

org.corpus_tools.pepper.impl.BeforeAfterAction

public class BeforeAfterAction
extends Object

This class is a helper class to perform actions before or after a mapping was done. A mapping could be the mapping of a single corpus or document or even the mapping of an entire corpus structure.

This could be helpful, for instance to make some processing after the mapping e.g. adding all created nodes and relations to a layer. To trigger an action for a specific Pepper module a set of customization properties is available. Customization properties triggering a post processing starts with . Such an action could be the enhancement of a corpus with metadata (following the property file syntax) to enhance corpora in formats, which do not support metadata, see readMeta(Identifier). Or the printing of a corpus structure, see #reportCorpusStructure(SNode, String, boolean).

Objects of this class are used by

1. PepperModuleImpl to perform actions before or after a single document or corpus was processed and
2. used by ModuleControllerImpl to perform actions before or after the entire corpus graph was processed.

This is an overview on the possible actions:

• single corpus or document
  • before
    • addSLayers(SDocument, String)
    • readMeta(Identifier)
  • after
    • addSLayers(SDocument, String)
• entire document structure
  • before
    • #reportCorpusStructure(SNode, String, boolean)
  • after
    • copyResources(String)

Constructor Detail

BeforeAfterAction

public BeforeAfterAction(PepperModule pepperModule)

Initializes this object and in case an action should be performed, it sets the internal PepperModule which does the action, and the internal SCorpusGraph on which the action should be performed.

Method Detail

getPepperModule

public PepperModule getPepperModule()

before

public void before(org.corpus_tools.salt.common.SCorpusGraph corpusGraph)
            throws PepperModuleException

Invokes an actions, after the mapping of an entire corpus structure was done. Customization properties triggering a pre processing starts with . This method is called before invocation of PepperModule.start().

Throws:

PepperModuleException

after

public void after(org.corpus_tools.salt.common.SCorpusGraph corpusGraph)
           throws PepperModuleException

Invokes an actions, after the mapping of an entire corpus structure was done. Customization properties triggering a post processing starts with . This method is called after invocation of {@link PepperModule#start()} .

Throws:

PepperModuleException

reportCorpusStructure

@Deprecated
protected String reportCorpusStructure(org.corpus_tools.salt.common.SCorpusGraph corpusGraph,
                                                   org.corpus_tools.salt.core.SNode node,
                                                   String prefix,
                                                   boolean isTail)

Deprecated. use instead

Returns the corpus structure as an ascii tree.

Parameters:

corpusGraph - the corpus structure to be printed

node - root node to start from

prefix -

isTail -

Returns:

copyResources

public void copyResources(String resString)

Reads customization property PepperModuleProperties.PROP_AFTER_COPY_RES and copies the listed resources to the named target folder.

before

public void before(org.corpus_tools.salt.graph.Identifier id)
            throws PepperModuleException

Invokes actions, before the mapping of a corpus or document was started. This could be helpful, for instance to make some preparations for the mapping. To trigger this pre processing for a specific Pepper module a set of customization properties is available. Customization properties triggering a pre processing starts with . This method is called by the method #map(), before PepperMapper.mapSDocument() was called.

Parameters:

id - id of either SDocument or SCorpus object to be prepared

Throws:

PepperModuleException

after

public void after(org.corpus_tools.salt.graph.Identifier id)
           throws PepperModuleException

Invokes actions, after the mapping of a corpus or document is done. This could be helpful, for instance to make some processing after the mapping e.g. adding all created nodes and relations to a layer. To trigger this post processing for a specific Pepper module a set of customization properties is available. Customization properties triggering a post processing starts with . This method is called by the method #map(), after PepperMapper.mapSDocument() was called.

Parameters:

id - id of either SDocument or SCorpus object to be post processed

Throws:

PepperModuleException

addSLayers

public void addSLayers(org.corpus_tools.salt.common.SDocument sDoc,
                       String layers)

Adds the passed layer to all nodes and objects in the passed SDocument.

Parameters:

sDoc -

layers -

readMeta

public void readMeta(org.corpus_tools.salt.graph.Identifier id)

Loads meta data form a meta data file and adds them to the object corresponding to the passed Identifier. The meta data file is localized in the directory in case of the URI corresponding to passed Identifier is a directory or (in case the corresponding URI addresses a file) in the same directory as the resource corresponding to the passed Identifier. The meta data file must have the ending passed in PepperModuleProperties.PROP_BEFORE_READ_META.

Parameters:

id - identifying the current object

renameAnnotations

public void renameAnnotations(org.corpus_tools.salt.graph.Identifier id,
                              String renameTemplate)

Renames all annotations matching the search template to the new namespace, name or value. To rename an annotation, use the following syntax: "old_namespace::old_name=old_value := new_namespace::new_name=new_value", determining the name is mandatory whereas the namespace and value are optional. For instance a pos annotation can be renamed as follows: "salt::pos:=part-of-speech". A list of renamings must be separated with ";".

Parameters:

id - identifying the current object
