function New-EmptyStructure { <# .SYNOPSIS Creates an empty object structure with all fields set to null (Pass 1). .DESCRIPTION This function creates a complete object structure based on the configuration, with all leaf fields set to null. This is Pass 1 of the three-pass generation process, which establishes the structure before populating any values. .PARAMETER Config The configuration hashtable defining the structure to create. .EXAMPLE New-EmptyStructure -Config $config Creates an empty structure with all fields set to null. .OUTPUTS A hashtable representing the empty structure. #> [CmdletBinding()] param( [Parameter(Mandatory = $true)] [hashtable]$Config ) $result = @{} foreach ($key in $Config.Keys) { $fieldConfig = $Config[$key] if ($fieldConfig -is [hashtable]) { if ($fieldConfig.ContainsKey('Type') -and $fieldConfig.Type -eq 'array') { # Array field $arrayCount = if ($fieldConfig.ContainsKey('ArrayCount')) { $fieldConfig.ArrayCount } else { 1 } if ($fieldConfig.ContainsKey('ItemStructure')) { # Array of objects - create array of empty structures $result[$key] = @(1..$arrayCount | ForEach-Object { New-EmptyStructure -Config $fieldConfig.ItemStructure }) } # Simple arrays without ItemStructure are not created in Pass 1 # They will be populated entirely in Pass 2 (Set-NonLinkedFields) } elseif ($fieldConfig.ContainsKey('Type')) { # Leaf field - set to null $result[$key] = $null } else { # Nested object - recurse $result[$key] = New-EmptyStructure -Config $fieldConfig } } } return $result } |
