SetField()

void Apache::Geode::Client::IWritablePdxInstance::SetField	(	String^	fieldName,
		Object^	value
	)

Set the existing named field to the given value.

The setField method has copy-on-write semantics. So for the modifications to be stored in the cache the WritablePdxInstance must be put into a region after setField has been called one or more times.

param name="fieldName"> name of the field whose value will be set

param name="value"> value that will be assigned to the field

exception cref="IllegalStateException"/> if the named field does not exist or if the type of the value is not compatible with the field
