ContentQuery

class ContentQuery [SourceType, IdType] extends AnyRef

Query on an arbitrary content source. See the content package overview for expected usage.

Note that as an implementation cheat, this internally represents query parameters (e.g., limitString) which not all ContentSources will support. We expect to stay safe because the publicly exported subclasses that you get from the content sources won't let users set the fields that the source can't support.

Abstract Value Members

  1. def count : Long

    Returns a count of records matching this query's conditions.

    Returns a count of records matching this query's conditions. May not be supported by all repositories; in particular, it is not supported by ContentProviders.

  3. def limit (s: String): ContentQuery[SourceType, IdType]

    Returns a new query whose results will be limited to the given number of rows.

  4. def order (s: String): ContentQuery[SourceType, IdType]

    Returns a new ContentQuery, equivalent to this one, except that results will be ordered as per the given String.

    Returns a new ContentQuery, equivalent to this one, except that results will be ordered as per the given String. Interpretation of the Strings is as per the underlying APIs, e.g., as for a SQL order by when querying a database.

  5. def where (s: String, vals: ContentValue*): ContentQuery[SourceType, IdType]

    Returns a new ContentQuery with the same semantics as this one, except that it adds extra conditions.

    Returns a new ContentQuery with the same semantics as this one, except that it adds extra conditions. If the condition contains '?' placeholders, they will be replaced with ContentValue arguments, e.g.

        qry = otherQuery.where( "created_at > ? and status = ?",
                            myDate.getTime, "in_progress" )

  6. def whereEq (pairs: (String, ContentValue)*): ContentQuery[SourceType, IdType]

    Returns a new ContentQuery with the same semantics as this one, except that it adds the condition that each of the fields named by the Strings in the arguments should be equal to the associated ContentValue.

    Returns a new ContentQuery with the same semantics as this one, except that it adds the condition that each of the fields named by the Strings in the arguments should be equal to the associated ContentValue. E.g.,

        qry = otherQuery.where( "status" -> "in_progress",
                            "urgency_level" -> 3 )

    using the same shorthand for pairs as is commonly used for Map constructors.
