Inheritance¶

Description¶

IJSONConsumer defines a standard interface for objects that consume JSON data during parsing. This interface provides methods that correspond to different JSON element types and structural events. Implementers of this interface can process JSON data as it is parsed without needing to create event handlers. The interface is used with TJSONConsumerReader for flexible JSON processing.

Methods¶

Member	Visibility	Description
BooleanValue	default	Processes a JSON boolean value
EndArray	default	Processes the end of a JSON array
EndObject	default	Processes the end of a JSON object
FloatValue	default	Processes a JSON floating-point value
Int64Value	default	Processes a JSON 64-bit integer value
IntegerValue	default	Processes a JSON integer value
KeyName	default	Processes a JSON object key name
NullValue	default	Processes a JSON null value
NumberValue	default	Processes a JSON number value as string
QWordValue	default	Processes a JSON quadword value
StartArray	default	Processes the start of a JSON array
StartObject	default	Processes the start of a JSON object
StringValue	default	Processes a JSON string value

Errors¶

Implementation-specific error handling depends on the implementing class.

Name	Description
TJSONConsumerReader	JSON reader that uses an IJSONConsumer for processing
TJSONEventReader	Event-based JSON reader that fires events for JSON elements
