Manipulating multiple documents

ArangoOperations.find

ArangoOperations.find(Iterable<String> ids, Class<T> entityClass) : Iterable<T>

Retrieves multiple documents with the given ids from a collection.

Arguments

• ids: Iterable<String>

  The ids or keys of the documents

• entityClass: Class<T>

  The entity type of the documents

Examples

@Autowired ArangoOperations template;

Iterable<MyObject> docs = template.find(Arrays.asList("some-id", "some-other-id"), MyObject.class);

ArangoOperations.findAll

ArangoOperations.findAll(Class<T> entityClass) : Iterable<T>

Retrieves all documents from a collection.

Arguments

• entityClass: Class<T>

  The entity class which represents the collection

Examples

@Autowired ArangoOperations template;

Iterable<MyObject> docs = template.find(MyObject.class);

ArangoOperations.insert

ArangoOperations.insert(Iterable<T> values, Class<T> entityClass, DocumentCreateOptions options) : MultiDocumentEntity

Creates new documents from the given documents, unless there is already a document with the _key given. If no _key is given, a new unique _key is generated automatically.

Arguments

• values: Iterable<T>

  A List of documents

• entityClass: Class<T>

  The entity class which represents the collection

• options: DocumentCreateOptions

  • waitForSync: Boolean

    Wait until document has been synced to disk.

  • returnNew: Boolean

    Return additionally the complete new document under the attribute new in the result.

  • returnOld: Boolean

    Additionally return the complete old document under the attribute old in the result. Only available if the overwrite option is used.

  • overwrite: Boolean

    If set to true, the insert becomes a replace-insert. If a document with the same _key already exists the new document is not rejected with unique constraint violated but will replace the old document.

  • silent: Boolean

    If set to true, an empty object will be returned as response. No meta-data will be returned for the created document. This option can be used to save some network traffic.

Examples

@Autowired ArangoOperations template;

MyObject obj1 = ...
MyObject obj2 = ...
MyObject obj3 = ...
template.insert(Arrays.asList(obj1, obj2, obj3));

ArangoOperations.replace

ArangoOperations.replace(Iterable<T> values, Class<T> entityClass, DocumentReplaceOptions options) : MultiDocumentEntity

Replaces multiple documents in the specified collection with the ones in the values, the replaced documents are specified by the _key attributes in the documents in values.

Arguments

• values: Iterable<T>

  A List of documents

• entityClass: Class<T>

  The entity class which represents the collection

• options: DocumentReplaceOptions

  • waitForSync: Boolean

    Wait until document has been synced to disk.

  • ignoreRevs: Boolean

    By default, or if this is set to true, the _rev attributes in the given document is ignored. If this is set to false, then the _rev attribute given in the body document is taken as a precondition. The document is only replaced if the current revision is the one specified.

  • ifMatch: String

    Replace a document based on target revision

  • returnNew: Boolean

    Return additionally the complete new document under the attribute new in the result.

  • returnOld: Boolean

    Additionally return the complete old document under the attribute old in the result. Only available if the overwrite option is used.

  • silent: Boolean

    If set to true, an empty object will be returned as response. No meta-data will be returned for the created document. This option can be used to save some network traffic.

Examples

@Autowired ArangoOperations template;

MyObject obj1 = ...
MyObject obj2 = ...
MyObject obj3 = ...
template.replace(Arrays.asList(obj1, obj2, obj3), new DocumentReplaceOptions());

ArangoOperations.update

ArangoOperations.update(Iterable<T> values, Class<T> entityClass, DocumentUpdateOptions options) : MultiDocumentEntity

Partially updates documents, the documents to update are specified by the _key attributes in the objects on values. Vales must contain a list of document updates with the attributes to patch (the patch documents). All attributes from the patch documents will be added to the existing documents if they do not yet exist, and overwritten in the existing documents if they do exist there.

Arguments

• values: Iterable<T>

  A List of documents

• entityClass: Class<T>

  The entity class which represents the collection

• options: DocumentUpdateOptions

  • waitForSync: Boolean

    Wait until document has been synced to disk.

  • ignoreRevs: Boolean

    By default, or if this is set to true, the _rev attributes in the given document is ignored. If this is set to false, then the _rev attribute given in the body document is taken as a precondition. The document is only replaced if the current revision is the one specified.

  • ifMatch: String

    Replace a document based on target revision

  • returnNew: Boolean

  • returnOld: Boolean

    Additionally return the complete old document under the attribute old in the result. Only available if the overwrite option is used.

  • silent: Boolean

    If set to true, an empty object will be returned as response. No meta-data will be returned for the created document. This option can be used to save some network traffic.

Examples

@Autowired ArangoOperations template;

MyObject obj1 = ...
MyObject obj2 = ...
MyObject obj3 = ...
template.update(Arrays.asList(obj1, obj2, obj3), new DocumentUpdateOptions());

ArangoOperations.delete

ArangoOperations.delete(Iterable<Object> values, Class<?> entityClass, DocumentDeleteOptions options) : MultiDocumentEntity

Deletes multiple documents from a collection.

Arguments

• values: Iterable<Object>

  The keys of the documents or the documents themselves

• entityClass: Class<?>

  The entity class which represents the collection

• options: DocumentDeleteOptions

  • waitForSync: Boolean

    Wait until document has been synced to disk.

  • ifMatch: String

    Replace a document based on target revision

  • returnOld: Boolean
