`GloopMethods`

The GloopMethods class contains a series of utility methods that are intended for use in Gloop only. These include:

Java system utility methods;
methods for running scripts;
methods for working with cursors;
throwing exceptions; and
creating Gloop models.

Not for Groovy

Most of the methods in GloopMethods deal with Gloop-specific objects; the remaining utility methods are already supported natively by Groovy and thus, this class does not provide much value for Groovy code.

`getSystemTime`

Use GloopMethods.getSystemTime() to get the current system time.

Return value

This method will return the system time in milliseconds as a long property.

Usage

`dynamicModelToMapModelArray`

Use this method to create a map-like Gloop model out of a given Gloop model. The result is an array of Gloop models; each with name and value properties. Every property in the source Gloop model will have its own entry in the resulting array. In these entries, the property name is mapped to the name property, and the value mapped to the value.

Example transformation using the dynamicModelToMapModelArray(GloopModel) method

For this example, let's assume the source Gloop model is the model below, represented in JSON:

{
    "TORO": "Cloud",
    "Martini": "Ninja"
}

When this method is used, the resulting array will be:

[
    {
        "name": "TORO",
        "value": "Cloud"
    },
    {
        "name": "Martini",
        "value": "Ninja"
    }
]

Parameters

Property	Type	Description
`anonymousModel`	`io.toro.gloop.object.property.GloopModel`	The Gloop model to be converted.

Return value

This method returns an array of io.toro.gloop.object.property.GloopModels; each model representing a property of anonymousModel.

Usage

Sample Gloop service showing how to use the `dynamicModelToMapModelArray` one-liner of `GloopMethods`

`mapModelArrayToDynamicModel`

mapModelArrayToDynamicModel(GloopModel) is used to create a model out of an array of models. Each model in the source array follows a specific structure; with a name and value property each. Using said method, the resulting Gloop model would have properties named after name properties and their values equal to the corresponding value property of each source model.

This method is the reverse counterpart of dynamicModelToMapModelArray(GloopModel).

Example transformation using the mapModelArrayToDynamicModel(GloopModel) method

Given the source array of models:

[
    {
        "name": "TORO",
        "value": "Cloud"
    },
    {
        "name": "Martini",
        "value": "Ninja"
    }
]

... the output of this method would be:

{
    "TORO": "Cloud",
    "Martini": "Ninja"
}

Parameters

Property	Type	Description
`model`	`io.toro.gloop.object.property.GloopModel`	The Gloop model to be converted.

Return value

This method returns a new io.toro.gloop.object.property.GloopModel, containing properties described by the source array of models.
