public interface SchematicEntry
extends Cloneable

A value used to store user's content (often a JSON document or a binary value) and metadata as an entry in a SchematicDb. These values also offer fine-grained locking and serialization of the value.

Method Detail

getMetadata

Document getMetadata()

Get the metadata associated with this value.

Returns:

the metadata document; never null

getContentType

String getContentType()

Get the media type describing the content.

Returns:

the media type; never null

getContent

Object getContent()

Return this value's content. The result will either be a Document or Binary. Note that this method will return a non-null value only if the hasDocumentContent() method returns true.

Returns:

the content, represented as a Document object, or null if there is no content

getContentAsDocument

Document getContentAsDocument()

Get this value's content, if it is a Document object. This method will always return a non-null Document if hasDocumentContent() returns true, and is therefore equivalent to the following:

 return hasDocumentContent() ? (Document)getContent() : null;
 

Returns:

the Document content, or null if there is no content or the content is a Binary value

getContentAsBinary

Binary getContentAsBinary()

Get this value's content, if it is a Binary object. This method will always return a non-null Binary if hasDocumentContent() returns false, and is therefore equivalent to the following:

 return hasDocumentContent() ? (Binary)getContent() : null;
 

Returns:

the Binary content, or null if there is no content or if the content is a Document

hasDocumentContent

boolean hasDocumentContent()

Return true if the getContent() method would return a Document (or getContentAsDocument() would return a non-null value).

This is equivalent to the following:

 return getContent() instanceof Document;
 

Returns:

true if the content is a Document, or false otherwise

hasBinaryContent

boolean hasBinaryContent()

Return true if the getContent() method would return a Binary (or getContentAsBinary() would return a non-null value).

This is equivalent to the following:

 return getContent() instanceof Binary;
 

Returns:

true if the content is a Binary value, or false otherwise

setContent

void setContent(Document content,
                Document metadata,
                String defaultContentType)

Set the content for this value to be the supplied Document and set the content type to be " application/json".

Parameters:

content - the Document representing the JSON content; may not be null

metadata - the Document representing the metadata; may be null

defaultContentType - the value for the MIME type describing the content that should be used if the metadata does not already contain a "contentType" field, and typically Schematic.ContentTypes.JSON, Schematic.ContentTypes.JSON_SCHEMA , or Schematic.ContentTypes.BSON; may not be null

setContent

void setContent(Binary content,
                Document metadata,
                String defaultContentType)

Set the content for this value to be the supplied Binary data described by the supplied content type.

Parameters:

content - the Binary representation of the content; may not be null

metadata - the Document representing the metadata; may be null

defaultContentType - the value for the MIME type describing the content that should be used if the metadata does not already contain a "contentType" field, and typically Schematic.ContentTypes.JSON, Schematic.ContentTypes.JSON_SCHEMA , or Schematic.ContentTypes.BSON; may not be null

editMetadata

EditableDocument editMetadata()

Get an editable metadata document. The client is expected to make these edits within the context of a transaction, and the edits will be saved when the transaction is committed.

Returns:

the editable representation of the document

editDocumentContent

EditableDocument editDocumentContent()

Get an editable document, when the content is a document. The client is expected to make these edits within the context of a transaction, and the edits will be saved when the transaction is committed.

Returns:

the editable representation of the content document

editMetadata()

asDocument

Document asDocument()

Get the representation of this entry as a document, which will include the metadata and content as nested documents.

Returns:

the entry's representation as a document
