ENVIDataContainer::AddToArray

Use the AddToArray method to insert data objects (such as rasters, vectors, or strings) into a data container array. If the specified container already exists, the new objects will be appended to the existing ones rather than replacing them.

Example

; Start the application

e = ENVI(/HEADLESS)

; Create a data container

container = ENVIDataContainer()

; Create an array for the data container

container.AddToArray, 'MyContainer', [10, 20, 30]

container.AddToArray, 'MyContainer', [40, 50]

Print, container.GetArray('MyContainer')

Syntax

ENVIDataContainer.AddToArray, Key, Value [, ERROR=value]

Arguments

Key

Specify a string identifier for the array.

Value

Specify the value of the data object to add.

Keywords

ERROR

Set this keyword to a named variable that will contain any error message issued during execution of this routine. If no error occurs, the ERROR variable will be set to a null string (''). If an error occurs and the routine is a function, then the function result will be undefined.

When this keyword is not set and an error occurs, ENVI returns to the caller and execution halts. In this case, the error message is contained within !ERROR_STATE and can be caught using IDL's CATCH routine. See IDL Help for more information on !ERROR_STATE and CATCH.

See Manage Errors for more information on error handling in ENVI programming.
