Method Detail

validateAlias

public void validateAlias(Alias alias,
                          String index,
                          MetaData metaData)

Allows to validate an Alias and make sure it's valid before it gets added to the index metadata. Doesn't validate the alias filter.

Throws:

IllegalArgumentException - if the alias is not valid

validateAliasMetaData

public void validateAliasMetaData(AliasMetaData aliasMetaData,
                                  String index,
                                  MetaData metaData)

Allows to validate an AliasMetaData and make sure it's valid before it gets added to the index metadata. Doesn't validate the alias filter.

Throws:

IllegalArgumentException - if the alias is not valid

validateAliasStandalone

public void validateAliasStandalone(Alias alias)

Allows to partially validate an alias, without knowing which index it'll get applied to. Useful with index templates containing aliases. Checks also that it is possible to parse the alias filter via XContentParser, without validating it as a filter though.

Throws:

IllegalArgumentException - if the alias is not valid

validateAlias

public void validateAlias(String alias,
                          String index,
                          @Nullable
                          String indexRouting,
                          Function<String,IndexMetaData> indexLookup)

Validate a proposed alias.

validateAliasFilter

public void validateAliasFilter(String alias,
                                String filter,
                                QueryShardContext queryShardContext,
                                NamedXContentRegistry xContentRegistry)

Validates an alias filter by parsing it using the provided QueryShardContext

Throws:

IllegalArgumentException - if the filter is not valid

validateAliasFilter

public void validateAliasFilter(String alias,
                                byte[] filter,
                                QueryShardContext queryShardContext,
                                NamedXContentRegistry xContentRegistry)

Validates an alias filter by parsing it using the provided QueryShardContext

Throws:
