Method Detail

init

protected void init(IndexSchema schema,
        Map<String,String> args)

Description copied from class: FieldType

subclasses should initialize themselves with the args provided and remove valid arguments. leftover arguments will cause an exception. Common boolean properties have already been handled.

Overrides:

init in class PrimitiveFieldType

createFields

public List<IndexableField> createFields(SchemaField field,
                                Object value,
                                float boost)

Description copied from class: FieldType

Given a SchemaField, create one or more IndexableField instances

Overrides:

createFields in class FieldType

Parameters:

field - the SchemaField

value - The value to add to the field

boost - The boost to apply

Returns:

An array of IndexableField

See Also:

FieldType.createField(SchemaField, Object, float), FieldType.isPolyField()

getSortField

public SortField getSortField(SchemaField field,
                     boolean reverse)

Description copied from class: FieldType

Returns the SortField instance that should be used to sort fields of this type.

Specified by:

getSortField in class FieldType

See Also:

SchemaField.checkSortability()

write

public void write(TextResponseWriter writer,
         String name,
         IndexableField f)
           throws IOException

Description copied from class: FieldType

calls back to TextResponseWriter to write the field value

Specified by:

write in class FieldType

Throws:

IOException

getValueSource

public ValueSource getValueSource(SchemaField field,
                         QParser parser)

Description copied from class: FieldType

called to get the default value source (normally, from the Lucene FieldCache.)

Overrides:

getValueSource in class FieldType

toObject

public Object toObject(SchemaField sf,
              BytesRef term)

Overrides:

toObject in class FieldType

checkSchemaField

public void checkSchemaField(SchemaField field)

Description copied from class: FieldType

Check's SchemaField instances constructed using this field type to ensure that they are valid.

This method is called by the SchemaField constructor to check that it's initialization does not violate any fundemental requirements of the FieldType. The default implementation does nothing, but subclasses may chose to throw a SolrException if invariants are violated by the SchemaField.

Overrides:

checkSchemaField in class FieldType
