Method Details

visitArray

public void visitArray(JavaType<?> elementJavaType,
 JdbcType elementJdbcType,
 Object[] values,
 WrapperOptions options,
 JsonDocumentWriter writer)

Serializes an array of values into JSON object/array

Parameters:

elementJavaType - the array element type

elementJdbcType - the JDBC type

values - values to be serialized

options - wrapping options

writer - the document writer used for serialization

visit

public void visit(MappingType mappedType,
 Object value,
 WrapperOptions options,
 JsonDocumentWriter writer)
           throws IOException

Throws:

IOException

handleNullOrLazy

protected boolean handleNullOrLazy(Object value,
 JsonDocumentWriter writer)

Checks the provided value is either null or a lazy property.

Parameters:

value - the value to check

writer - the current JsonDocumentWriter

Returns:

true if it was, indicating no further processing of the value is needed, false otherwise.

serializeObjectValues

protected void serializeObjectValues(ManagedMappingType managedMappingType,
 Object object,
 WrapperOptions options,
 JsonDocumentWriter writer)
                              throws IOException

JSON object managed type serialization.

Parameters:

managedMappingType - the managed mapping type of the given object

object - the object to be serialized

options - wrapping options

writer - the document writer

Throws:

IOException - if an error occurred while writing to an underlying writer
