Element Detail

help

public abstract java.lang.String help

A short help description to appear alongside the field in a UI.

label

public abstract java.lang.String label

The label that should be displayed for the field if the name is insufficient.

Default:

""

required

public abstract boolean required

Is this field required, or is the default value generally sufficient?

Default:

false

level

public abstract API.Level level

How important is this field? The web UI uses the level to do a slow reveal of the parameters.

Default:

water.api.API.Level.critical

direction

public abstract API.Direction direction

Is this field an input, output or inout?

Default:

water.api.API.Direction.INPUT

values

public abstract java.lang.String[] values

For enum-type fields the allowed values are specified using the values annotation. This is used in UIs to tell the user the allowed values, and for validation.

Default:

{}

valuesProvider

public abstract java.lang.Class<? extends ValuesProvider> valuesProvider

Proovide values for enum-like types if it cannot be provided as a constant in annotation.

Default:

water.api.ValuesProvider.class

json

public abstract boolean json

Should this field be rendered in the JSON representation?

Default:

true

is_member_of_frames

public abstract java.lang.String[] is_member_of_frames

For Vec-type fields this is the set of Frame-type fields which must contain the named column. For example, for a SupervisedModel the response_column must be in both the training_frame and (if it's set) the validation_frame.

Default:

{}

is_mutually_exclusive_with

public abstract java.lang.String[] is_mutually_exclusive_with

For Vec-type fields this is the set of other Vec-type fields which must contain mutually exclusive values. For example, for a SupervisedModel the response_column must be mutually exclusive with the weights_column.

Default:

{}

gridable

public abstract boolean gridable

Identify grid-able parameter.

Default:

false
