Functions

func ApplyTranslation 

func ApplyTranslation(element interface{}, key, formatString string) (string, error)

ApplyTranslation translate a templated string using informations in an Event

func AsString

AsString tries to convert an interface{} into a string, and returns its value and an integer indicating whether it succeeded or not.

func ExitOnError 

func ExitOnError(err error, msg string)

ExitOnError calls log.Fatalf if err != nil

func FailOnError 

func FailOnError(err error, msg string)

FailOnError calls log.Panicf if err != nil

func FindStringSubmatchMap 

func FindStringSubmatchMap(re *regexp.Regexp, s string) map[string]string

FindStringSubmatchMap returns a map containing the values of the named subexpressions of the lefmost match of the regular expression re in s. A return value of nil indicates no match.

func FindStringSubmatchMapWithRegexExpression 

func FindStringSubmatchMapWithRegexExpression(re RegexExpression, s string) map[string]string

FindStringSubmatchMap returns a map containing the values of the named subexpressions of the lefmost match of the regular expression re in s. A return value of nil indicates no match.

func GetField 

func GetField(object interface{}, fieldPath string) (interface{}, error)

GetField returns the value of a field of an object or a map, given the field's name as a string. Multiple field names may be chained, separated by dots: 

GetField(alarm_value, "State.Value")

An error is returned if the field does not exist. If the field is a pointer, it will be dereferenced before being returned. Note that GetField cannot return map keys that contain a dot.

Types

type OptionalBool 

type OptionalBool struct {
	// Set is a boolean indicating whether the value was set or not.
	Set bool

	// Value contains the value of the bool. It should only be taken into
	// account if Set is true.
	Value bool
}

OptionalBool is a wrapper around bool that implements the bson.Setter interface.

Using this type instead of bool in a struct allows to :

  • check whether the value was set or not in the bson document.
  • raise an error when trying to unmarshal a value that is not an integer.

Note that when trying to unmarshal a value that is not a bool, UnmarshalBSONValue will raise an error that will not be handled by bson.Unmarshal. If this error is not handled in the UnmarshalBSONValue method of an ancestor, calls to MongoDB queries may fail.

func (OptionalBool) MarshalBSONValue 

func (s OptionalBool) MarshalBSONValue() (bsontype.Type, []byte, error)

func (*OptionalBool) UnmarshalBSONValue 

func (s *OptionalBool) UnmarshalBSONValue(valueType bsontype.Type, b []byte) error

type OptionalInt64 

type OptionalInt64 struct {
	// Set is a boolean indicating whether the value was set or not.
	Set bool

	// Value contains the value of the int64. It should only be taken into
	// account if Set is true.
	Value int64
}

OptionalInt64 is a wrapper around int64 that implements the bson.Setter interface.

Using this type instead of int64 in a struct allows to :

  • check whether the value was set or not in the bson document.
  • raise an error when trying to unmarshal a value that is not an integer.

Note that when trying to unmarshal a value that is not an integer, UnmarshalBSONValue will raise an error that will not be handled by bson.Unmarshal. If this error is not handled in the UnmarshalBSONValue method of an ancestor, calls to MongoDB queries may fail.

func (OptionalInt64) MarshalBSONValue 

func (i OptionalInt64) MarshalBSONValue() (bsontype.Type, []byte, error)

func (*OptionalInt64) UnmarshalBSONValue 

func (i *OptionalInt64) UnmarshalBSONValue(valueType bsontype.Type, b []byte) error

type OptionalInterface 

type OptionalInterface struct {
	// Set is a boolean indicating whether the value was set or not.
	Set bool

	// Value contains the value of the interface{}. It should only be taken
	// into account if Set is true.
	Value interface{}
}

OptionalInterface is a wrapper around interface{} that implements the bson.Setter interface.

Using this type instead of interface{} in a struct allows to check whether the value was set or not in the bson document.

func (OptionalInterface) MarshalBSONValue 

func (i OptionalInterface) MarshalBSONValue() (bsontype.Type, []byte, error)

func (*OptionalInterface) UnmarshalBSONValue 

func (i *OptionalInterface) UnmarshalBSONValue(valueType bsontype.Type, b []byte) error

type OptionalRegexp 

type OptionalRegexp struct {
	// Set is a boolean indicating whether the value was set or not.
	Set bool

	// Value contains the value of the regular expression. It should only be
	// taken into account if Set is true.
	Value RegexExpression
}

OptionalRegexp is a wrapper around regexp.Regexp that implements the bson.Setter interface.

Using this type in a struct allows to :

  • check whether the value was set or not in the bson document.
  • automatically compile a regular expression.
  • raise an error when trying to unmarshal a value that is not a valid regular expression.

Note that when trying to unmarshal a value that is not a valid regular expression, UnmarshalBSONValue will raise an error that will not be handled by bson.Unmarshal. If this error is not handled in the UnmarshalBSONValue method of an ancestor, calls to MongoDB queries may fail.

func (OptionalRegexp) MarshalBSONValue 

func (r OptionalRegexp) MarshalBSONValue() (bsontype.Type, []byte, error)

func (*OptionalRegexp) UnmarshalBSONValue 

func (r *OptionalRegexp) UnmarshalBSONValue(valueType bsontype.Type, b []byte) error

type OptionalString 

type OptionalString struct {
	// Set is a boolean indicating whether the value was set or not.
	Set bool

	// Value contains the value of the string. It should only be taken into
	// account if Set is true.
	Value string
}

OptionalString is a wrapper around string that implements the bson.Setter interface.

Using this type instead of string in a struct allows to :

  • check whether the value was set or not in the bson document.
  • raise an error when trying to unmarshal a value that is not an integer.

Note that when trying to unmarshal a value that is not a string, UnmarshalBSONValue will raise an error that will not be handled by bson.Unmarshal. If this error is not handled in the UnmarshalBSONValue method of an ancestor, calls to MongoDB queries may fail.

func (a OptionalStringArray) MarshalBSONValue() (bsontype.Type, []byte, error)

func (*OptionalStringArray) UnmarshalBSONValue 

func (a *OptionalStringArray) UnmarshalBSONValue(valueType bsontype.Type, b []byte) error

type OptionalTemplate 

type OptionalTemplate struct {
	// Set is a boolean indicating whether the value was set or not.
	Set bool

	// Value contains the value of the regular expression. It should only be
	// taken into account if Set is true.
	Value *template.Template
}

OptionalTemplate is a wrapper around template.Template that implements the bson.Setter interface.

Using this type in a struct allows to :

  • check whether the value was set or not in the bson document.
  • automatically compile a template.
  • raise an error when trying to unmarshal a value that is not a valid template.

Note that when trying to unmarshal a value that is not a valid template, UnmarshalBSONValue will raise an error that will not be handled by bson.Unmarshal. If this error is not handled in the UnmarshalBSONValue method of an ancestor, calls to MongoDB queries may fail.
