ParameterBuilder

Implements

IParameterBuilder

Namespace: TehGM.Wolfringo.Commands.Parsing

Assembly: Wolfringo.Commands.dll

Syntax

public class ParameterBuilder : IParameterBuilder

Methods

BuildParamsAsync(IEnumerable<ParameterInfo>, ParameterBuilderValues, CancellationToken)

Builds parameters.

Declaration

public async Task<ParameterBuildingResult> BuildParamsAsync(IEnumerable<ParameterInfo> parameters, ParameterBuilderValues values, CancellationToken cancellationToken = default(CancellationToken))

Parameters

Type	Name	Description
System.Collections.Generic.IEnumerable<System.Reflection.ParameterInfo>	parameters	Collection of parameters to be built.
ParameterBuilderValues	values	Values to use when building params.
System.Threading.CancellationToken	cancellationToken	Cancellation token used to cancel building

Returns

Type	Description
System.Threading.Tasks.Task<ParameterBuildingResult>	Result of the parameters building.

IsParamAssignable(ParameterInfo, Object)

Checks if parameter can be assigned from given object.

Declaration

protected static bool IsParamAssignable(ParameterInfo parameter, object value)

Parameters

Type	Name	Description
System.Reflection.ParameterInfo	parameter	The parameter info.
System.Object	value	The object to check.

Returns

Type	Description
System.Boolean	True if object can be assigned to given param; otherwise false.

Remarks

This check does null check in addition to reflection type check.

This method is intended to be internal helper reducing code repetition.

IsParamAssignable(Type, Object)

Checks if parameter can be assigned from given object.

Declaration

protected static bool IsParamAssignable(Type type, object value)

Parameters

Type	Name	Description
System.Type	type	Type of the parameter.
System.Object	value	The object to check.

Returns

Type	Description
System.Boolean	True if object can be assigned to given param; otherwise false.

Remarks

This check does null check in addition to reflection type check.

This method is intended to be internal helper reducing code repetition.

TryConvertArgument(ParameterInfo, Int32, ParameterBuilderValues, out Object, out Exception)

Attempts to convert argument to parameter type.

Declaration

protected static bool TryConvertArgument(ParameterInfo parameter, int argIndex, ParameterBuilderValues values, out object result, out Exception error)

Parameters

Type	Name	Description
System.Reflection.ParameterInfo	parameter	Parameter to convert argument to.
System.Int32	argIndex	Index of argument.
ParameterBuilderValues	values	Builder values. Must contain Args and ArgumentConverterProvider.
System.Object	result	Result of the conversion. Null if conversion failed.
System.Exception	error	Exception that occured when converting. Null if there was no exception.

Returns

Type	Description
System.Boolean	True if converting was successful; otherwise false.

TryFindAdditional(Type, IEnumerable<Object>, out Object)

Attempts to find an object of specific type from enumerable of objects.

Declaration

protected static bool TryFindAdditional(Type type, IEnumerable<object> additionals, out object result)

Parameters

Type	Name	Description
System.Type	type	Type of object to find.
System.Collections.Generic.IEnumerable<System.Object>	additionals	Enumerable of objects to find from.
System.Object	result	Found object. Null if not found.

Returns

Type	Description
System.Boolean	True if object was found successfully; otherwise false.

TryGetAttribute<T>(ParameterInfo, out T)

Attempts to get an attribute present on the parameter.

Declaration

protected static bool TryGetAttribute<T>(ParameterInfo parameter, out T result)
    where T : Attribute

Parameters

Type	Name	Description
System.Reflection.ParameterInfo	parameter
T	result

Returns

Type	Description
System.Boolean

Type Parameters

Name	Description
T

TryGetGenericLogger(Type, IServiceProvider, out Object)

Attempts to create a generic ILogger>T<.

Declaration

public static bool TryGetGenericLogger(Type type, IServiceProvider services, out object result)

Parameters

Type	Name	Description
System.Type	type	Parameter type to create the logger for.
System.IServiceProvider	services	Service provider to get logger factory from.
System.Object	result	Created logger. Null if failed to create.

Returns

Type	Description
System.Boolean	True if successfully created the logger. Otherwise false.

TryGetService(Type, IServiceProvider, out Object)

Attempts to find a service of type from service provider.

Declaration

public static bool TryGetService(Type type, IServiceProvider services, out object result)

Parameters

Type	Name	Description
System.Type	type	Type of service to find.
System.IServiceProvider	services	Service provider to get service from.
System.Object	result	Found service. Null if not found.

Returns

Type	Description
System.Boolean	True if service was found successfully; otherwise false.
