Constructor Detail

SchemaField

public SchemaField(String name,
           FieldType type)

Create a new SchemaField with the given name and type, using all the default properties from the type.

SchemaField

public SchemaField(SchemaField prototype,
           String name)

Create a new SchemaField from an existing one by using all of the properties of the prototype except the field name.

SchemaField

public SchemaField(String name,
           FieldType type,
           int properties,
           String defaultValue)

Create a new SchemaField with the given name and type, and with the specified properties. Properties are *not* inherited from the type in this case, so users of this constructor should derive the properties from type.getProperties() using all the default properties from the type.

Method Detail

getName

public String getName()

getType

public FieldType getType()

indexed

public boolean indexed()

stored

public boolean stored()

storeTermVector

public boolean storeTermVector()

storeTermPositions

public boolean storeTermPositions()

storeTermOffsets

public boolean storeTermOffsets()

omitNorms

public boolean omitNorms()

omitTf

@Deprecated
public boolean omitTf()

Deprecated. Use omitTermFreqAndPositions()

omitTermFreqAndPositions

public boolean omitTermFreqAndPositions()

omitPositions

public boolean omitPositions()

public boolean isRequired()

createField

public IndexableField createField(Object val,
                         float boost)

createFields

public IndexableField[] createFields(Object val,
                            float boost)

isPolyField

public boolean isPolyField()

If true, then use createFields(Object, float), else use createField(java.lang.Object, float) to save an extra allocation

Returns:

true if this field is a poly field

toString

public String toString()

Overrides:

toString in class Object

write

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

Throws:

IOException

getSortField

public SortField getSortField(boolean top)

Delegates to the FieldType for this field

See Also:

FieldType.getSortField(org.apache.solr.schema.SchemaField, boolean)

checkSortability

public void checkSortability()
                      throws SolrException

Sanity checks that the properties of this field type are plausible for a field that may be used in sorting, throwing an appropriate exception (including the field name) if it is not. FieldType subclasses can choose to call this method in their getSortField implementation

Throws:

SolrException

See Also:

FieldType.getSortField(org.apache.solr.schema.SchemaField, boolean)

checkFieldCacheSource

public void checkFieldCacheSource(QParser parser)
                           throws SolrException

Sanity checks that the properties of this field type are plausible for a field that may be used to get a FieldCacheSource, throwing an appropriate exception (including the field name) if it is not. FieldType subclasses can choose to call this method in their getValueSource implementation

Throws:

SolrException

See Also:

FieldType.getValueSource(org.apache.solr.schema.SchemaField, org.apache.solr.search.QParser)

getDefaultValue

public String getDefaultValue()

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object
