Examples with JsonPatch org.hisp.dhis.commons.jackson.jsonpatch.JsonPatch used on opensource projects

Example 1 with JsonPatch

use of org.hisp.dhis.commons.jackson.jsonpatch.JsonPatch in project dhis2-core by dhis2.

the class JsonPatchManager method apply.

/**
 * Applies a JSON patch to any valid jackson java object. It uses
 * valueToTree to convert from the object into a tree like node structure,
 * and this is where the patch will be applied. This means that any property
 * renaming etc will be followed.
 *
 * @param patch JsonPatch object with the operations it should apply.
 * @param object Jackson Object to apply the patch to.
 * @return New instance of the object with the patch applied.

    // we need to make another trip to make sure all collections are
    // correctly made into json nodes.
