/**
* RESTEasy handler to provide the JCR resources at the URIs below. Please note that these URIs assume a context of
* {@code /resources} for the web application.
*
*
* URI Pattern
* Description
* Supported Methods
*
*
* /resources
* returns a list of accessible repositories
* GET
*
*
* /resources/{repositoryName}
* returns a list of accessible workspaces within that repository
* GET
*
*
* /resources/{repositoryName}/{workspaceName}
* returns a list of operations within the workspace
* GET
*
*
* /resources/{repositoryName}/{workspaceName}/items/{path}
* accesses the item (node or property) at the path
* GET, POST, PUT, DELETE
*
*
* /resources/{repositoryName}/{workspaceName}/query
* executes the query in the body of the request with a language specified by the content type (application/jcr+xpath,
* application/jcr+sql, application/jcr+sql2, or application/search)
* POST
*
*
* Binary data
*
* There are several ways to transfer binary property values, but all involve encoding the binary value into ASCII characters
* using a {@link Base64} notation and denoting this by adding annotating the property name with a suffix defining the type of
* encoding. Currently, only "base64" encoding is supported.
*
*
* For example, if the "jcr:data" property contains a single binary value of "propertyValue", then the JSON object representing
* that property will be:
*
*
* "jcr:data/base64/" : "cHJvcGVydHlWYWx1ZQ=="
*
*
* Likewise, if the "jcr:data" property contains two binary values each being "propertyValue", then the JSON object representing
* that property will be:
*
*
* "jcr:data/base64/" : [ "cHJvcGVydHlWYWx1ZQ==", "cHJvcGVydHlWYWx1ZQ==" ]
*
*
* Note that JCR 1.0.1 does not allow property names to and with a '/' character (among others), while JCR 2.0 does not allow
* property names to contain an unescaped or unencoded '/' character. Therefore, the "/{encoding}/" suffix can never appear in a
* valid JCR property name, and will always identify an encoded property.
*
*
* Here are the details:
*
* - Getting a node with
GET /resources/{repositoryName}/item/{pathToNode} obtains the JSON object representing the
* node, and each property is represented as a nested JSON object where the name is the property name and the value(s) are
* represented as either a single string value or an array of string values. If the property has a binary value, then the property
* name is appended with "/base64/" and the string representation of each value is encoded in Base64.
* - Getting a property with
GET /resources/{repositoryName}/item/{pathToProperty} allows only the value(s) for the
* one property to be included in the response. If any of the values is a binary value, then all of the values will be
* encoded in Base64.
* - Setting a property with
PUT /resources/{repositoryName}/item/{pathToProperty} allows setting the property to a
* single value, and only that value needs to be included in the body of the request. If the value is binary, the value
* must be {@link Base64 encoded} by the client and the "Content-Transfer-Encoding" header must be set to "base64" (case
* does not matter). When the request is received, the value is decoded before the property value is updated on the node.
* - Creating a node with
POST /resources/{repositoryName}/item/{pathToNode} requires a request that is structured
* in the same way as the response from getting a node: the resulting JSON object represents the node, with nested JSON objects
* for the properties and children. If any property of the new node has a binary value, then the name of the property must
* be appended with "/base64/" and the string representation of each value are to be encoded in Base64.
* - Updating a node with
PUT /resources/{repositoryName}/item/{pathToNode} requires a request that is structured
* in the same way as the response from getting or posting a node: the resulting JSON object represents the node, with nested JSON
* objects for the properties and children. If any property of the new node has a binary value, then the name of the property
* must be appended with "/base64/" and the string representation of each value are to be encoded in Base64.
