Constructor Detail

AlterEnvironmentRequest

public AlterEnvironmentRequest()

Constructs an AlterEnvironmentRequest object with default parameters.

AlterEnvironmentRequest

public AlterEnvironmentRequest(String environmentName,
                               String action,
                               String value,
                               Map<String,String> options)

Constructs an AlterEnvironmentRequest object with the specified parameters.

Parameters:

environmentName - Name of the environment to be altered.

action - Modification operation to be applied. Supported values:

• INSTALL_PACKAGE: Install a python package from PyPI, an external data source or KiFS
• INSTALL_REQUIREMENTS: Install packages from a requirements file
• UNINSTALL_PACKAGE: Uninstall a python package.
• UNINSTALL_REQUIREMENTS: Uninstall packages from a requirements file
• RESET: Uninstalls all packages in the environment and resets it to the original state at time of creation
• REBUILD: Recreates the environment and re-installs all packages, upgrades the packages if necessary based on dependencies

value - The value of the modification, depending on action. For example, if action is INSTALL_PACKAGE, this would be the python package name. If action is INSTALL_REQUIREMENTS, this would be the path of a requirements file from which to install packages. If an external data source is specified in DATASOURCE_NAME, this can be the path to a wheel file or source archive. Alternatively, if installing from a file (wheel or source archive), the value may be a reference to a file in KiFS.

options - Optional parameters.

• DATASOURCE_NAME: Name of an existing external data source from which packages specified in value can be loaded

The default value is an empty Map.
