Constructor Detail

TypeMapping

public TypeMapping(String typeAlias)

creates a TypeMapping for given alias and class. Both, alias and class must be unique per index.

Method Detail

getTypeAlias

public String getTypeAlias()

Returns:

the mapping's alias which translates directly to an elasticsearch type

getTypeClass

public abstract Class<?> getTypeClass()

getIdClass

public abstract Class<?> getIdClass()

isFiltered

public boolean isFiltered(@Nonnull
                 Object o)

Simple filtering of entities. esi4j core library will always respect this filtering when working with mapped objects. Users are still free to persist entities anyway.

Returns:

true if entity must not be persisted to index

isVersioned

public abstract boolean isVersioned()

Returns:

true if all object's of mapped type are supposed to be versioned. Note that it isn't required to call this method before getVersion(Object)

getId

public abstract Object getId(@Nonnull
           Object o)

Returns:

the object's id

See Also:

#setId(Object, Object)

getIdString

public final String getIdString(@Nonnull
                 Object o)

Returns:

the object's id as a string suitable for elasticsearch

See Also:

getId(Object), toIdString(Object)

toIdString

public abstract String toIdString(@Nonnull
                Object id)

Returns:

convert id to a string representation suitable for elasticsearch. never null if id is not null

See Also:

toId(String)

toId

public abstract Object toId(@Nonnull
          String id)

Returns:

convert string representation suitable for elasticsearch to id

See Also:

toIdString(Object)

getVersion

public abstract Long getVersion(Object o)

gets version from object or null if not versioned

getMappingSource

public abstract MappingSource getMappingSource(org.elasticsearch.common.settings.Settings indexSettings)

Returns:

a new MappingSource for this type

getObjectSource

public abstract ObjectSource getObjectSource(Object o)

Returns:

a new ObjectSource for this object

read

@CheckForNull
public abstract Object read(org.elasticsearch.action.get.GetResponse response)

Returns:

the object returned by a GetResponse or null if not applicable or doc doesn't exist

read

@CheckForNull
public abstract Object read(org.elasticsearch.search.SearchHit hit)

Returns:

the object returned by a SearchHit or null if not applicable

indexRequest

Returns:

null if object is filtered
