IndexEntryContainerSize

public IndexEntryContainerSize()

Method Detail

getIndexKey

public Long getIndexKey()

Description copied from class: IndexEntry

Get the value which is indexed by this instance. It serves as 2nd part of the unique key together with the property fieldMeta.

Specified by:

getIndexKey in class IndexEntry

Returns:

the key.

setIndexKey

protected void setIndexKey(Object indexKey)

Specified by:

setIndexKey in class IndexEntry

getClassMeta

public ClassMeta getClassMeta()

Get the ClassMeta of the concrete type of the instance containing the field.

If a field is declared in a super-class, all sub-classes have it, too. But when querying instances of a sub-class (either as candidate-class or in a relation (as concrete type of the field/property), only this given sub-class and its sub-classes should be found.

The ClassMeta here is either the same as fieldMeta.classMeta (if it is an instance of the class declaring the field) or a ClassMeta of a sub-class of fieldMeta.classMeta.

The IndexEntryContainerSize always uses the FieldMeta.classMeta as classMeta.

Overrides:

getClassMeta in class IndexEntry

Returns:

the ClassMeta of the concrete type of the instance containing the field.
