描述----------Description----------
The Quickload class represents a Quickload data source, essentially directory layout separating tracks and sequences by genome, along with a few metadata files. This interface abstracts those details and provides access to a Quickload at any URL supported by R (HTTP, FTP, and local files). This is an easy way to make data accessible to the Integrated Genome Browser (IGB).
类Quickload代表Quickload数据源,基本上目录布局随着几元数据文件,分离轨道和基因组序列。此接口抽象这些细节,并提供由R(HTTP,FTP和本地文件)支持的任何URL访问到Quickload。这是一个简单的方法,使数据访问的综合基因组浏览器(IGB)。
构造----------Constructor----------
Quickload(uri = "quickload", create = FALSE): Constructs a new Quickload object, representing a repository at uri. If create is TRUE, and uri is writeable (i.e., local), the repository is created if it does not already exist. If it does exist, then a message is emitted to indicate that the repository was not recreated.
Quickload(uri = "quickload", create = FALSE):构造一个新的Quickload对象,代表在uri库。 create如果是TRUE,uri是可写(即本地),库被创建,如果它已经不存在。如果它确实存在,那么发出消息表明仓库重建。
存取方法----------Accessor Methods----------
In the code snippets below, x represents a Quickload object.
在下面的代码片段,xQuickload对象。
x$genome, x[["genome"]]: Get the QuickloadGenome object for the genome named genome. This is where all the data is stored.
x$genome,x[["genome"]]:获取基因组名为QuickloadGenomegenome对象。这是所有的数据存储。
length(x): number of genomes in the repository
length(x):库中的基因组
uri(x): Get the URI pointing to the Quickload repository.
uri(x):获取URI指向的Quickload库。
genome(x): Get the identifiers of the genomes present in the repository.
genome(x):获取基因组标识符库中的呈现。
