Function Get-AtwsRole
{


<#
.SYNOPSIS
This function get one or more Role through the Autotask Web Services API.
.DESCRIPTION
This function creates a query based on any parameters you give and returns any resulting objects from the Autotask Web Services Api. By default the function returns any objects with properties that are Equal (-eq) to the value of the parameter. To give you more flexibility you can modify the operator by using -NotEquals [ParameterName[]], -LessThan [ParameterName[]] and so on.

Possible operators for all parameters are:
 -NotEquals
 -GreaterThan
 -GreaterThanOrEqual
 -LessThan
 -LessThanOrEquals

Additional operators for [string] parameters are:
 -Like (supports * or % as wildcards)
 -NotLike
 -BeginsWith
 -EndsWith
 -Contains

Properties with picklists are:


Entities that have fields that refer to the base entity of this CmdLet:

BillingItem
 ContractExclusionRole
 ContractExclusionSetExcludedRole
 ContractFactor
 ContractRate
 ContractRoleCost
 PriceListRole
 QuoteItem
 Resource
 ResourceRole
 ResourceRoleDepartment
 ResourceRoleQueue
 ResourceServiceDeskRole
 Task
 TaskSecondaryResource
 Ticket
 TicketSecondaryResource
 TimeEntry

.INPUTS
Nothing. This function only takes parameters.
.OUTPUTS
[Autotask.Role[]]. This function outputs the Autotask.Role that was returned by the API.
.EXAMPLE
Get-AtwsRole -Id 0
Returns the object with Id 0, if any.
 .EXAMPLE
Get-AtwsRole -RoleName SomeName
Returns the object with RoleName 'SomeName', if any.
 .EXAMPLE
Get-AtwsRole -RoleName 'Some Name'
Returns the object with RoleName 'Some Name', if any.
 .EXAMPLE
Get-AtwsRole -RoleName 'Some Name' -NotEquals RoleName
Returns any objects with a RoleName that is NOT equal to 'Some Name', if any.
 .EXAMPLE
Get-AtwsRole -RoleName SomeName* -Like RoleName
Returns any object with a RoleName that matches the simple pattern 'SomeName*'. Supported wildcards are * and %.
 .EXAMPLE
Get-AtwsRole -RoleName SomeName* -NotLike RoleName
Returns any object with a RoleName that DOES NOT match the simple pattern 'SomeName*'. Supported wildcards are * and %.
