Method Detail

emit

public void emit(String emitKey,
                 List<Metadata> metadataList)
          throws IOException,
                 TikaEmitterException

Specified by:

emit in interface Emitter

Throws:

IOException

TikaEmitterException

emit

public void emit(List<? extends EmitData> batch)
          throws IOException,
                 TikaEmitterException

Description copied from class: AbstractEmitter

The default behavior is to call Emitter.emit(String, List) on each item. Some implementations, e.g. Solr/ES/vespa, can benefit from subclassing this and emitting a bunch of docs at once.

Specified by:

emit in interface Emitter

Overrides:

emit in class AbstractEmitter

Throws:

IOException

TikaEmitterException

setAttachmentStrategy

@Field
public void setAttachmentStrategy(String attachmentStrategy)

Options: SKIP, CONCATENATE_CONTENT, PARENT_CHILD. Default is "PARENT_CHILD". If set to "SKIP", this will index only the main file and ignore all info in the attachments. If set to "CONCATENATE_CONTENT", this will concatenate the content extracted from the attachments into the main document and then index the main document with the concatenated content _and_ the main document's metadata (metadata from attachments will be thrown away). If set to "PARENT_CHILD", this will index the attachments as children of the parent document via Solr's parent-child relationship.

setUpdateStrategy

@Field
public void setUpdateStrategy(String updateStrategy)

setConnectionTimeout

@Field
public void setConnectionTimeout(int connectionTimeout)

setSocketTimeout

@Field
public void setSocketTimeout(int socketTimeout)

getCommitWithin

public int getCommitWithin()

setCommitWithin

@Field
public void setCommitWithin(int commitWithin)

setIdField

@Field
public void setIdField(String idField)

Specify the field in the first Metadata that should be used as the id field for the document.

Parameters:

idField -

setSolrCollection

@Field
public void setSolrCollection(String solrCollection)

setSolrUrls

@Field
public void setSolrUrls(List<String> solrUrls)

setSolrZkHosts

@Field
public void setSolrZkHosts(List<String> solrZkHosts)

setSolrZkChroot

@Field
public void setSolrZkChroot(String solrZkChroot)

setUserName

@Field
public void setUserName(String userName)

setPassword

@Field
public void setPassword(String password)

setAuthScheme

@Field
public void setAuthScheme(String authScheme)

setProxyHost

@Field
public void setProxyHost(String proxyHost)

setProxyPort

@Field
public void setProxyPort(int proxyPort)

setEmbeddedFileFieldName

@Field
public void setEmbeddedFileFieldName(String embeddedFileFieldName)

If using the SolrEmitter.AttachmentStrategy.PARENT_CHILD, this is the field name used to store the child documents. Note that we artificially flatten all embedded documents, no matter how nested in the container document, into direct children of the root document.

Parameters:

embeddedFileFieldName -

initialize

public void initialize(Map<String,Param> params)
                throws TikaConfigException

Specified by:

initialize in interface Initializable

Parameters:

params - params to use for initialization

Throws:

TikaConfigException

checkInitialization

public void checkInitialization(InitializableProblemHandler problemHandler)
                         throws TikaConfigException

Specified by:

checkInitialization in interface Initializable

Parameters:

problemHandler - if there is a problem and no custom initializableProblemHandler has been configured via Initializable parameters, this is called to respond.

Throws:

TikaConfigException
