problem, sc_req_item, ticket, ast_transfer_order, planned_task, change_task, change_phase, sc_request]

TableUtils - getHierarchy()

Returns a list of all classes participating in the hierarchy of the specified table.

표 12. Parameters
Name	Type	Description
None

표 13. Returns
Type	Description
ArrayList	A list of all classes in the specified table's hierarchy.

var table = new TableUtils("cmdb_ci_server");

TableUtils - getTables()

Returns the table hierarchy.

표 14. Parameters
Name	Type	Description
None

표 15. Returns
Type	Description
ArrayList	A list of table names in the parent hierarchy.

// Get the hierarchy of tables
var table = new TableUtils("cmdb_ci_computer");
var tableArrayList = table.getTables();

// Use the j2js method to convert the Java ArrayList to JavaScript
gs.include("j2js");
var tableArray = j2js(tableArrayList);

// Write the value of each element in the JavaScript array
var i = 0;
while ( i < tableArray.length ) {
gs.print("Table with index " + i + ": " + tableArray[i]);
i++;
}

Output:

Table with index 0: cmdb_ci_computer

TableUtils - getTableExtensions()

Returns a list of tables that extend a table.

표 16. Parameters
Name	Type	Description

표 17. Returns
Type	Description
ArrayList	A list of table names that extend the table.

This example shows that 58 tables in this instance extend the Computer [cmdb_ci_computer] table. (Output condensed below.)

// Get the tables that extend the table
var table = new TableUtils("cmdb_ci_computer");
var tableArrayList = table.getTableExtensions();
 
// Use the j2js method to convert the Java ArrayList to JavaScript
gs.include("j2js");
var tableArray = j2js(tableArrayList);
 
// Write the value of each element in the JavaScript array
var i = 0;
while ( i < tableArray.length ) {
  gs.print("Table with index " + i + ": " + tableArray[i]);
  i++;
}

TableUtils - hasExtensions()

Determines if a table has been extended.

표 18. Parameters
Name	Type	Description
None

표 19. Returns
Type	Description
Boolean	True if the table has extensions.

var table = new TableUtils("cmdb_ci_server");
gs.print(table.hasExtensions());

Output:

true

TableUtils - isBaseClass()

Determines if a table is a base class, meaning it has no parents and has extensions.

For example, Task is a base class since it is not extended from another table and has tables extended from it. Sys_user is not a base class because it has no parents, but does not have extensions.

표 20. Parameters

var table = new TableUtils("task");
gs.print("Task is base class: " + table.isBaseClass());
 
var table = new TableUtils("sys_user");
gs.print("User is base class: " + table.isBaseClass());

Output:

 Task is base class: true
User is base class: false

TableUtils - isSoloClass()
