                         throws IOException

Throws:

IOException

FieldCapabilitiesRequest

Method Details

writeTo

public void writeTo(StreamOutput out)
             throws IOException

Description copied from interface: Writeable

Write this into the StreamOutput.

Specified by:

writeTo in interface Writeable

Overrides:

writeTo in class ActionRequest

Throws:

IOException

toXContent

public XContentBuilder toXContent(XContentBuilder builder,
 ToXContent.Params params)
                           throws IOException

Specified by:

toXContent in interface ToXContent

Throws:

IOException

fields

public FieldCapabilitiesRequest fields(String... fields)

The list of field names to retrieve

fields

public String[] fields()

indices

public FieldCapabilitiesRequest indices(String... indices)

The list of indices to lookup

Specified by:

indices in interface IndicesRequest.Replaceable

indicesOptions

public FieldCapabilitiesRequest indicesOptions(IndicesOptions indicesOptions)

includeUnmapped

public FieldCapabilitiesRequest includeUnmapped(boolean includeUnmapped)

indices

public String[] indices()

Description copied from interface: IndicesRequest

Returns the array of indices that the action relates to

Specified by:

indices in interface IndicesRequest

indicesOptions

public IndicesOptions indicesOptions()

Description copied from interface: IndicesRequest

Returns the indices options used to resolve indices. They tell for instance whether a single index is accepted, whether an empty array will be converted to _all, and how wildcards will be expanded if needed.

Specified by:

indicesOptions in interface IndicesRequest

allowsRemoteIndices

public boolean allowsRemoteIndices()

Description copied from interface: IndicesRequest.Replaceable

Determines whether the request can contain indices on a remote cluster. NOTE in theory this method can belong to the IndicesRequest interface because whether a request allowing remote indices has no inherent relationship to whether it is IndicesRequest.Replaceable or not. However, we don't have an existing request that is non-replaceable but allows remote indices. In addition, authorization code currently relies on the fact that non-replaceable requests do not allow remote indices. That said, it is possible to remove this constraint should the needs arise in the future. We just need proceed with extra caution.

Specified by:

allowsRemoteIndices in interface IndicesRequest.Replaceable

includeDataStreams

public boolean includeDataStreams()

Description copied from interface: IndicesRequest

Determines whether the request should be applied to data streams. When false, none of the names or wildcard expressions in IndicesRequest.indices() should be applied to or expanded to any data streams. All layers involved in the request's fulfillment including security, name resolution, etc., should respect this flag.

Specified by:

includeDataStreams in interface IndicesRequest

includeUnmapped

public boolean includeUnmapped()

indexFilter

public FieldCapabilitiesRequest indexFilter(QueryBuilder indexFilter)

Allows to filter indices if the provided QueryBuilder rewrites to `match_none` on every shard.

indexFilter

public QueryBuilder indexFilter()

runtimeFields

public FieldCapabilitiesRequest runtimeFields(Map<String,Object> runtimeFieldsSection)

Allows adding search runtime fields if provided.

runtimeFields

public Map<String,Object> runtimeFields()

validate

public ActionRequestValidationException validate()

Specified by:

validate in class ActionRequest

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

getDescription

public String getDescription()

Description copied from interface: TaskAwareRequest

Returns optional description of the request to be displayed by the task manager

Specified by:

getDescription in interface TaskAwareRequest
