.SYNOPSIS
|
|
Tests for binary operators with -band if a specific Value contains binary
|
|
operators within a Compare array. In addition you can use a Namespace
|
|
argument to provide a hashtable in which your key values are included to
|
|
reduce the amount of code to write
|
|
.DESCRIPTION
|
|
Tests for binary operators with -band if a specific Value contains binary
|
|
operators within a Compare array. In addition you can use a Namespace
|
|
argument to provide a hashtable in which your key values are included to
|
|
reduce the amount of code to write
|
|
.EXAMPLE
|
|
PS>Test-IcingaBinaryOperator -Value Ok -Compare EmptyClass, InvalidNameSpace, PermissionError, Ok -Namespace $TestIcingaWindowsInfoEnums.TestIcingaWindowsInfo;
|
|
True
|
|
.EXAMPLE
|
|
PS>Test-IcingaBinaryOperator -Value 2 -Compare 1,4,8,16,32,64,128,256;
|
|
False
|
|
.PARAMETER Value
|
|
The value to check if it is included within the compare argument. This can either be
|
|
the name of the key for a Namespace or a numeric value
|
|
.PARAMETER Compare
|
|
An array of values to compare for and check if the value matches with the -band operator
|
|
The array can either contain the key names of your Namespace, numeric values or both combined
|
|
.PARAMETER Namespace
|
|
A hashtable object containing values you want to compare for. By providing a hashtable here
|
|
you can use the key names for each value on the Value and Compare argument
