Note that the objects in this module do *not* mutate any arguments. No type version happens here. It is up to another layer to properly convert arguments to any required types. Validation Errors ----------------- N)datetime)ParamValidationError)is_json_value_headerparse_to_aware_datetimecCs,t}|||}|r(t|ddS)avValidates input parameters against a schema. This is a convenience function that validates parameters against a schema. You can also instantiate and use the ParamValidator class directly if you want more control. If there are any validation errors then a ParamValidationError will be raised. If there are no validation errors than no exception is raised and a value of None is returned. :param params: The user provided input parameters. :type shape: botocore.model.Shape :param shape: The schema which the input parameters should adhere to. :raise: ParamValidationError reportN)ParamValidatorvalidate has_errorsrgenerate_report)paramsshapeZ validatorrr5/tmp/pip-unpacked-wheel-ozje0y8b/botocore/validate.pyvalidate_parameterss rcsfdd}|S)Ncsfdd}fdd|S)Ncs |||r|||||SdSNrselfparamr errorsname _type_checkfuncrr_on_passes_type_check4s zKtype_check.._create_type_check_guard.._on_passes_type_checkcs2t|s.ddD}|j|d||ddSdS)NcSsg|] }t|qSrstr.0trrr :szUtype_check.._create_type_check_guard.._type_check.. invalid typer valid_typesFT) isinstancer)rrrvalid_type_namesr#rrr8s zAtype_check.._create_type_check_guard.._type_checkr)rrr&rr_create_type_check_guard3s z,type_check.._create_type_check_guardr)r#r'rr&r type_check2s r(cCsnd}td}d|jkr.|jd}||krTd}n&t|drT|jdrTd}||krTd}|rj|j||||ddS) NFz-infminT serializationZ hostLabel)r min_allowed)floatmetadatahasattrr*getr)rvaluer error_typerfailedr,rrr range_checkIs    r4c@s<eZdZddZddZddZddZd d Zd d Zd S)ValidationErrorscCs g|_dSr_errorsrrrr__init__[szValidationErrors.__init__cCs|jr dSdSNTFr6r8rrrr ^szValidationErrors.has_errorscCs*g}|jD]}|||q d|S)N )r7append _format_errorjoin)rZerror_messageserrorrrrr cs z ValidationErrors.generate_reportc Cs|\}}}||}|dkr2d|d|ddS|dkrf|d}d|d }d |d|d |S|d kr|d }t|}d|d} d|d|d|d| S|dkr|d }|d} d|d|d| S|dkr|d }|d} d|d|d| S|dkr d||dS|dkrd|d }t|}d|d} d|d|d|d| S|dkrd|d } d!|d"| d#S|d$krd|d } d%|d&| d#SdS)'Nmissing required fieldzMissing required parameter in z: " required_name" unknown field unknown_paramz, valid_nameszUnknown parameter in z", must be one of: r!rr#zInvalid type for parameter z , value: z, type: z, valid types: invalid ranger,zInvalid value for parameter z, valid min value: invalid lengthzInvalid length for parameter z, valid min length: unable to encode to jsonz2Invalid parameter {} must be json serializable: {} type_errorinvalid type for documentz$Invalid type for document parameter more than one inputmembersztypeformat) rr?r2r additionalrDrEr param_typer#r,rLrrrr=isZ       zValidationErrors._format_errorcCs&|sdS|dr|ddS|SdS)NinputrMr+) startswith)rrrrrrOs   zValidationErrors._get_namecKs|j|||fdSr)r7r<)rrreasonkwargsrrrrszValidationErrors.reportN) __name__ __module__ __qualname__r9r r r=rOrrrrrr5Zs @r5c@seZdZdZddZddZddZdd Zd d Ze e fd d dZ e e fd ddZ e eefd ddZe e fd ddZe efd ddZddZe efd ddZe eejfefd ddZeZe efd ddZdd Zd!d"Zd#S)$rz+Validates parameters against a shape model.cCst}|j|||dd|S)aValidate parameters against a shape model.
