InputRangeAttributes

Purpose

This module provides a set of custom attributes used to annotate gain-related enum values with metadata controlling input range behavior for data acquisition hardware. The attributes allow fine-grained control over gain availability, disabled states, and input range boundaries (min/max/firmware values) in millivolts, supporting different hardware configurations including modified vs unmodified Gen 3 SPS devices.

Public Interface

GainDisabledAttribute : Attribute

• GainDisabledAttribute(bool disabled) - Constructor; marks a gain as disabled when disabled is true.
• static bool IsGainDisabled(object o) - Returns true if the object (typically an enum value) has GainDisabledAttribute with _bDisabled = true. Returns false if null, no member found, or attribute not present.

MaxInputRangeAttribute : Attribute

• MaxInputRangeAttribute(double maxInputRangemV) - Constructor; sets maximum input range in mV.
• static double GetMaxInputRangemV(object o) - Returns the maximum input range in mV for the given object. Returns 0D if null, no member found, or attribute not present.

GainAvailableUnmodifiedAttribute : Attribute

• GainAvailableUnmodifiedAttribute(bool available) - Constructor; marks availability for unmodified Gen 3 SPS.
• static bool IsGainAvailableToUnmodified(object o) - Returns true if gain is available to unmodified Gen 3 SPS. Returns true by default (if attribute not present). Returns false only if attribute is present with available = false.

MinInputRangeAttribute : Attribute

• MinInputRangeAttribute(double minInputRangemV) - Constructor; sets minimum input range in mV.
• static double GetMinInputRangemV(object o) - Returns the minimum input range in mV for the given object. Returns 0D if null, no member found, or attribute not present.

FirmwareInputRangeAttribute : Attribute

• FirmwareInputRangeAttribute(double firmwareInputRangemV) - Constructor; sets the input range value to send to firmware.
• static double GetFirmwareInputRangemV(object o) - Returns the firmware input range in mV for the given object. Returns 0D if null, no member found, or attribute not present.

Invariants

• All static retrieval methods accept object (intended for enum values) and use reflection via GetMember(o.ToString()).
• Default behaviors:
  • IsGainDisabled: returns false (gains are enabled by default)
  • IsGainAvailableToUnmodified: returns true (available by default)
  • Range getters: return 0D if attribute not present
• All attributes are in namespace DTS.DASLib.Service despite folder location suggesting otherwise.

Dependencies

• Depends on: System (for Attribute and reflection APIs)
• Depended on by: Unclear from source alone - likely gain-related enums in the data acquisition service layer.

Gotchas

• Namespace mismatch: The namespace DTS.DASLib.Service does not match the folder path DataPRO/IService/Classes/InputRangeAttributes. A ReSharper comment suppresses namespace check.
• FogBugz references: Comments reference internal bug tracker URLs (e.g., http://fogbugz/fogbugz/default.asp?10080) which are inaccessible externally.
• Reflection assumption: The static methods assume o.ToString() returns a valid member name; if o is not an enum or the string doesn't match a member, methods return default values silently.
• Typo in field name: FirmwareInputRangeAttribute._firmwareInputRangeAttribute - the field name repeats the class name rather than describing the value.
