Class com.fasterxml.jackson.core.JsonGenerator

Examples of com.fasterxml.jackson.core.JsonGenerator.writeStartArray()

com.fasterxml.jackson.core.JsonGenerator.writeStartArray()
Method for writing starting marker of a Array value (for JSON this is character '['; plus possible white space decoration if pretty-printing is enabled).
Array values can be written in any context where values are allowed: meaning everywhere except for when a field name is expected.
