Class DocumentFactoryConfig

java.lang.Object

com.snowtide.pdf.lucene.DocumentFactoryConfig

public class DocumentFactoryConfig
extends java.lang.Object

Instances of this class are used to control the creation of Lucene Documents from PDF content through the PDFDocumentFactory class. Typical usage of this class would be to create a static instance, configure it as desired, and use that static instance whenever a new Lucene Document instance is built through the PDFDocumentFactory class.

Constructor Detail

DocumentFactoryConfig

public DocumentFactoryConfig(java.lang.String mainTextFieldName)

Creates a new config object. The resulting object retains the default configuration except for the name assigned to the Lucene Field that contains the main PDF text content.

Parameters:

mainTextFieldName - - the name that should be assigned to Fields containing the main PDF text content.

DocumentFactoryConfig

public DocumentFactoryConfig()

Creates a new config object. Fields containing the main text content of PDF's converted into Lucene Document instances will be assigned a default name. Other configuration defaults are as follows:

• All PDF document attributes are copied to the resulting Lucene documents
• The main text content is tokenized and indexed, but not stored
• The PDF document attributes are tokenized, stored, and indexed.

Method Detail

setMainTextFieldName

public void setMainTextFieldName(java.lang.String mainTextFieldName)

Sets the name that will be assigned to Lucene Fields containing the main text content of PDF's converted to Lucene Documents via the PDFDocumentFactory class.

getMainTextFieldName

public java.lang.String getMainTextFieldName()

Returns the name that will be assigned to the field that holds the main body text of each PDF document converted into a Lucene Document instance through the PDFDocumentFactory class using this config object.

getFieldName

public java.lang.String getFieldName(java.lang.String pdfAttrName)

Returns the name that will be assigned to Fields containing the value of the PDF document attribute identified within the PDF document by the provided attribute name.

pdfAttrNames

public java.util.Set pdfAttrNames()

Returns a Set of the PDF document attribute names that are mapped to Field names in this config object. All objects in the returned Set are strings.

setFieldName

public void setFieldName(java.lang.String pdfAttrName,
                java.lang.String fieldName)

Sets the name that will be assigned to Fields corresponding to the provided PDF document attribute name.

copyAllPDFAttrs

public boolean copyAllPDFAttrs()

Returns true if this object is configured to ensure that all PDF document attributes will be added to generated Lucene Documents, even if no attribute name / field name mapping has been established in this config object.

setCopyAllPDFAttrs

public void setCopyAllPDFAttrs(boolean b)

Setter corresponding to the copyAllPDFAttrs attribute.

copyAllPDFAttrs()

setTextSettings

public void setTextSettings(boolean store,
                   boolean index,
                   boolean token)

Sets Field attributes that will be used when creating the Field object for the main text content of a PDF document. These attributes correspond to the store, index, and token parameters of the Lucene Field constructor.

setPDFAttrSettings

public void setPDFAttrSettings(boolean store,
                      boolean index,
                      boolean token)

Sets Field attributes that will be used when creating Field objects for the document attributes found in a PDF document. These attributes correspond to the store, index, and token parameters of the Lucene Field constructor.
