Examples with ObjectParser org.elasticsearch.common.xcontent.ObjectParser used on opensource projects

Example 1 with ObjectParser

use of org.elasticsearch.common.xcontent.ObjectParser in project elasticsearch by elastic.

the class AbstractAllocateAllocationCommand method createAllocateParser.

protected static <T extends Builder<?>> ObjectParser<T, Void> createAllocateParser(String command) {
    ObjectParser<T, Void> parser = new ObjectParser<>(command);
    parser.declareString(Builder::setIndex, new ParseField(INDEX_FIELD));

Example 2 with ObjectParser

use of org.elasticsearch.common.xcontent.ObjectParser in project elasticsearch by elastic.

the class SearchHit method declareMetaDataFields.
