Constructors

ParameterDescriptor(ParameterInfo)

Initializes a new instance of the ParameterDescriptor class.

Declaration
public ParameterDescriptor(ParameterInfo pi)
Parameters
ParameterInfo pi

A ParameterInfo taken from reflection.

ParameterDescriptor(String, Type, Boolean, Object, Boolean, Boolean, Boolean)

Initializes a new instance of the ParameterDescriptor class.

Declaration
public ParameterDescriptor(string name, Type type, bool hasDefaultValue = false, object defaultValue = null, bool isOut = false, bool isRef = false, bool isVarArgs = false)
Parameters
System.String name

The name.
Type type

The type.
System.Boolean hasDefaultValue

if set to true the parameter has default value.
System.Object defaultValue

The default value.
System.Boolean isOut

if set to true, is an out param.
System.Boolean isRef

if set to true is a ref param.
System.Boolean isVarArgs

if set to true is variable arguments param.

ParameterDescriptor(String, Type, Boolean, Object, Boolean, Boolean, Boolean, Type)

Initializes a new instance of the ParameterDescriptor class.

Declaration
public ParameterDescriptor(string name, Type type, bool hasDefaultValue, object defaultValue, bool isOut, bool isRef, bool isVarArgs, Type typeRestriction)
Parameters
System.String name

The name.
Type type

The type.
System.Boolean hasDefaultValue

if set to true the parameter has default value.
System.Object defaultValue

The default value.
System.Boolean isOut

if set to true, is an out param.
System.Boolean isRef

if set to true is a ref param.
System.Boolean isVarArgs

if set to true is variable arguments param.
Type typeRestriction

The type restriction, or nll.

Properties

DefaultValue

Gets the default value

Declaration
public object DefaultValue { get; }
Property Value
System.Object

HasBeenRestricted

Gets a value indicating whether this instance has been restricted.

Declaration
public bool HasBeenRestricted { get; }
Property Value
System.Boolean

HasDefaultValue

Gets a value indicating whether this instance has a default value.

Declaration
public bool HasDefaultValue { get; }
Property Value
System.Boolean

IsOut

Gets a value indicating whether this instance is an out parameter

Declaration
public bool IsOut { get; }
Property Value
System.Boolean

IsRef

Gets a value indicating whether this instance is a "ref" parameter

Declaration
public bool IsRef { get; }
Property Value
System.Boolean

IsVarArgs

Gets a value indicating whether this instance is a variable arguments param

Declaration
public bool IsVarArgs { get; }
Property Value
System.Boolean

Name

Gets the name of the parameter

Declaration
public string Name { get; }
Property Value
System.String

OriginalType

Gets the original type of the parameter before any restriction has been applied.

Declaration
public Type OriginalType { get; }
Property Value
Type

Type

Gets the type of the parameter

Declaration
public Type Type { get; }
Property Value
Type

Methods

PrepareForWiring(Table)

Prepares the descriptor for hard-wiring. The descriptor fills the passed table with all the needed data for hardwire generators to generate the appropriate code.

Declaration
public void PrepareForWiring(Table table)
Parameters
Table table

Implements

RestrictType(Type)

Restricts the type of this parameter to a tighter constraint. Restrictions must be applied before the IOverloadableMemberDescriptor containing this parameter is used in any way.

Declaration
public void RestrictType(Type type)
Parameters
Type type

The new type.
Exceptions
System.InvalidOperationException

Cannot restrict a ref/out or varargs param or Specified operation is not a restriction

ToString()

Returns a System.String that represents this instance.

Declaration
public override string ToString()
Returns
System.String

A System.String that represents this instance.
Overrides
System.Object.ToString()
