- Method Detail
  - type
```
JsonEventType type()
```
    Returns:
    
    the type of the event
  - fieldName
```
String fieldName()
```
    Returns:
    
    the name of the field when the event is emitted as a JSON object member
  - value
```
Object value()
```
    Returns:
    
    the json value for JsonEventType.VALUE events
  - isNumber
```
boolean isNumber()
```
    Returns:
    
    true when the JSON value is a number
  - integerValue
```
Integer integerValue()
```
    Returns:
    
    the Integer value or null if the event has no JSON value
    
    Throws:
    
    ClassCastException - if the value is not an Integer
  - longValue
```
Long longValue()
```
    Returns:
    
    the Long value or null if the event has no JSON value
    
    Throws:
    
    ClassCastException - if the value is not a Long
  - floatValue
```
Float floatValue()
```
    Returns:
    
    the Float value or null if the event has no JSON value
    
    Throws:
    
    ClassCastException - if the value is not a Float
  - doubleValue
```
Double doubleValue()
```
    Returns:
    
    the Double value or null if the event has no JSON value
    
    Throws:
    
    ClassCastException - if the value is not a Double
  - isBoolean
```
boolean isBoolean()
```
    Returns:
    
    true when the JSON value is a boolean
  - booleanValue
```
Boolean booleanValue()
```
    Returns:
    
    the Boolean value or null if the event has no JSON value
    
    Throws:
    
    ClassCastException - if the value is not a Boolean
  - isString
```
boolean isString()
```
    Returns:
    
    true when the JSON value is a string
  - stringValue
```
String stringValue()
```
    Returns:
    
    the string value or null if the event has no JSON value
    
    Throws:
    
    ClassCastException - if the value is not a string
  - binaryValue
```
Buffer binaryValue()
```
    Return the binary value.
    JSON itself has no notion of a binary, this extension complies to the RFC-7493, so this method assumes there is a String value with the key and it contains a Base64 encoded binary, which it decodes if found and returns.
    
    Returns:
    
    the binary value or null if the event has no JSON value
    
    Throws:
    
    ClassCastException - if the value is not a String
    
    IllegalArgumentException - if the String value is not a legal Base64 encoded value
  - instantValue
```
java.time.Instant instantValue()
```
    Return the Instant value.
    JSON itself has no notion of a temporal types, this extension complies to the RFC-7493, so this method assumes there is a String value with the key and it contains an ISO 8601 encoded date and time format such as "2017-04-03T10:25:41Z", which it decodes if found and returns.
    
    Returns:
    
    the Instant value or null if the event has no JSON value
    
    Throws:
    
    ClassCastException - if the value is not a String
    
    java.time.format.DateTimeParseException - if the String value is not a legal ISO 8601 encoded value
  - isNull
```
boolean isNull()
```
    Returns:
    
    true when the JSON value is null
  - isObject
```
boolean isObject()
```
    Returns:
    
    true when the JSON value is a JSON object
  - objectValue
```
JsonObject objectValue()
```
    Returns:
    
    the JSON object value or null if the event has no JSON value
    
    Throws:
    
    ClassCastException - if the value is not a JSON object
  - isArray
```
boolean isArray()
```
    Returns:
    
    true when the JSON value is a JSON array
  - arrayValue
```
JsonArray arrayValue()
```
    Returns:
    
    the JSON array value or null if the event has no JSON value
    
    Throws:
    
    ClassCastException - if the value is not a JSON array
  - mapTo
```
<T> T mapTo(Class<T> type)
```
    Decodes and returns the current value as the specified type.
    
    Parameters:
    
    type - the type to decode the value to
    
    Returns:
    
    the decoded value
  - mapTo
```
<T> T mapTo(TypeReference<T> type)
```
    Decodes and returns the current value as the specified type.
    
    Parameters:
    
    type - the type to decode the value to
    
    Returns:
    
    the decoded value
