getModel

RecordHolder getModel(ExecutionContext ctx,
                      String name)
               throws ErrorException

Returns a model with the specified name or null, if there is no such a model. If there are several models with the same name (and arbitrary version) on the server, the most recently uploaded model is returned.

Parameters:

ctx -

name -

Returns:

a model with the specified name

Throws:

ErrorException

getModel

RecordHolder getModel(ExecutionContext ctx,
                      String name,
                      String version)
               throws ErrorException

Returns a model with the specified name and version, or null, if there is no such a model instance. If there are several models with the same name and version on the server, the most recently uploaded model is returned.

Parameters:

ctx -

name -

version -

Returns:

a model with the specified name and version

Throws:

findModels

SetHolder findModels(ExecutionContext ctx,
                     String name,
                     String version,
                     Boolean latestOnly)

Returns a set of all uploaded models satisfying the specified filtering criteria. If the corresponding fields of a model match the patterns specified as function parameters, the model is included in the resulting set. All strings in parameters are specified as wildcard strings patterns. A wildcard string can contain the following wildcards: “*” matching none or several arbitrary characters, and “?” matching exactly one arbitrary character. Any other character in patterns matches itself. �null’ specified as the pattern value matches any value of the model field (which is equivalent to the “*” pattern). Setting the latestOnly parameter to true causes including only the most recently uploaded models with given name and version, if there are several models with the same name and version on the server. If the latestOnly parameter is set to false, all models satisfying the filtering criteria are returned; the returned set can contain several models of the same name and version.

ctx -

name -

version -

latestOnly -

Returns:

a set of all uploaded models satisfying the specified filtering criteria
