Parameters

database

Type: OSIsoft.AFAFDatabase
The AFDatabase to search for the requested objects.

searchRoot

Type: OSIsoft.AF.AssetAFElement
The root object to start the search. If , then the search starts at the AFDatabase.

nameFilter

Type: SystemString

The element name filter string used for finding objects.

The query string (or match pattern) can include regular characters and wildcard characters. Regular characters must match exactly the characters specified in the query string. Wildcard characters can be matched with arbitrary fragments of the query string. Wildcard characters can be escaped using the single backslash (\) character. Use a double backslash (\\) to match a single backslash. The syntax of the query string has the following rules:

• If or empty string, then everything will be matched.
• If no wildcards, then an exact match on the query string is performed.
• Wildcard * can be placed anywhere in the query string and matches zero or more characters.
• Wildcard ? can be placed anywhere in the query string and matches exactly one character.
• One character in a set of characters are matched by placing them within [ ]. For example, a[bc] would match 'ab' or 'ac', but it would not match 'ad' or 'abd'.
• One character in a set of characters are not matched by placing them within [! ]. For example, a[!bc] would match 'ad', but it would not match 'ab', 'ac', or 'abd'.
• A character in a range of characters from first to last are matched using the following syntax: [first - last]. For example, a[a-c] would match 'aa', 'ab', or 'ac', but it would not match 'ad' or 'abc'.

elemCategory

Type: OSIsoft.AFAFCategory
Specify that the owner of the returned attributes must have this category. To not filter by element category, then specify for this parameter.

elemTemplate

Type: OSIsoft.AF.AssetAFElementTemplate
Specify that the owner of the returned attributes must have this template or a template derived from this template. To not filter by element template, then specify for this parameter.

elemType

Type: OSIsoft.AF.AssetAFElementType
Specify that the element of the returned attributes must have this Type. To not filter by element type, then specify AFElementType.Any for this parameter.

attrNameFilter

Type: SystemString

The attribute name filter string used for finding objects.

The query string (or match pattern) can include regular characters and wildcard characters. Regular characters must match exactly the characters specified in the query string. Wildcard characters can be matched with arbitrary fragments of the query string. Wildcard characters can be escaped using the single backslash (\) character. Use a double backslash (\\) to match a single backslash. The syntax of the query string has the following rules:

• If or empty string, then everything will be matched.
• If no wildcards, then an exact match on the query string is performed.
• Wildcard * can be placed anywhere in the query string and matches zero or more characters.
• Wildcard ? can be placed anywhere in the query string and matches exactly one character.
• One character in a set of characters are matched by placing them within [ ]. For example, a[bc] would match 'ab' or 'ac', but it would not match 'ad' or 'abd'.
• One character in a set of characters are not matched by placing them within [! ]. For example, a[!bc] would match 'ad', but it would not match 'ab', 'ac', or 'abd'.
• A character in a range of characters from first to last are matched using the following syntax: [first - last]. For example, a[a-c] would match 'aa', 'ab', or 'ac', but it would not match 'ad' or 'abc'.

attrCategory

Type: OSIsoft.AFAFCategory
Specify that returned attributes must have this category. To not filter by attribute category, then specify for this parameter.

attrType

Type: SystemTypeCode
Specify that returned attributes must have this Type. To not filter by attribute type, then specify Empty. If Object is specified, then attributes which do not have a type defined (displayed as Anything in PI System Explorer), will be returned, as well as types which cannot be described by a simpler type code, such as enumeration values, arrays, files, and references to other AF objects.

searchFullHierarchy

Type: SystemBoolean
Specifies if the search should include objects nested further than the immediate children of the searchRoot.

sortField

Type: OSIsoft.AFAFSortField
The field or property of the object used to sort the returned collection. This value should not be changed between calls when attempting to get the next page of items.

sortOrder

Type: OSIsoft.AFAFSortOrder
The order that the returned collection is sorted. This value should not be changed between calls when attempting to get the next page of items.

startIndex

Type: SystemInt32
The starting index (zero based) of the items to be returned.

maxCount

Type: SystemInt32
The maximum number of objects to be returned per call (the page size).

totalCount

Type: SystemInt32
The total number of objects that match the search criteria.

Return Value

AFSDK
