直系の既知のサブクラス:

XContentStructure.InnerQuery

public abstract class XContentStructure
extends Object

XContentStructure is a class used to capture a subset of query, to be parsed at a later time when more information (in this case, types) is available. Note that using this class requires copying the parser's data, which will result in additional overhead versus parsing the inner query/filter immediately, however, the extra overhead means that the type not be extracted prior to query parsing (in the case of unordered JSON).

XContentStructure

public XContentStructure(QueryParseContext queryParseContext)

Create a new XContentStructure for the current parsing context.

メソッドの詳細

freeze

public XContentStructure freeze()
                         throws IOException

"Freeze" the parsing content, which means copying the current parser's structure into an internal BytesReference to be parsed later.

戻り値:

the original XContentStructure object

例外:

IOException

bytes

public void bytes(BytesReference innerBytes)

Set the bytes to be used for parsing

bytes

public BytesReference bytes()

Return the bytes that are going to be used for parsing

asQuery

public org.apache.lucene.search.Query asQuery(String... types)
                                       throws IOException

Use the captured bytes to parse the inner query using the specified types. The original QueryParseContext's parser is switched during this parsing, so this method is NOT thread-safe.

パラメータ:

types - types to be used during the inner query parsing

戻り値:

Query parsed from the bytes captured in freeze()

例外:

IOException
