= Gda::Value Hacking
This document describes the plan on how to convert Gda::Value's to Ruby types.
== Conversions
:Gda::Value#TYPE_BIGINT
LL2NUM()
:Gda::Value#TYPE_BUGUINT
ULL2NUM()
:Gda::Value#TYPE_BINARY
packed String
:Gda::Value#TYPE_BLOB
- IO or turn to String with GdaBlob->stringify()
+ Convert to Gda::Blob (via RBGDA_BLOB)
:Gda::Value#TYPE_BOOLEAN
CBOOL2RVAL()
:Gda::Value#TYPE_DATE
rb_time_new()
:Gda::Value#TYPE_DOUBLE
rb_float_new()
:Gda::Value#TYPE_GEOMETRIC_POINT
rb_ary_new() or rb_struct_new()
:Gda::Value#TYPE_GOBJECT
GObject (some hacking may be necessary)
:Gda::Value#TYPE_INTEGER
INT2NUM()
:Gda::Value#TYPE_LIST
rb_ary_new()+rb_ary_push()
:Gda::Value#TYPE_MONEY
rb_hash_new() or rb_struct_new()
:Gda::Value#TYPE_NUMERIC
INT2NUM/UINT2NUM/LL2NUM/ULL2NUM/rb_float_new
:Gda::Value#TYPE_NULL
Qnil
:Gda::Value#TYPE_SINGLE
rb_float_new()
:Gda::Value#TYPE_SMALLINT
INT2FIX()
:Gda::Value#TYPE_SMALLUINT
UINT2NUM()
:Gda::Value#TYPE_STRING
CSTR2RVAL()
:Gda::Value#TYPE_TIME
rb_ary_new() or rb_hash_new() or rb_struct_new()
:Gda::Value#TYPE_TIMESTAMP
rb_time_new()
:Gda::Value#TYPE_TINYINT
INT2FIX()
:Gda::Value#TYPE_TINYUINT
UINT2NUM()
:Gda::Value#TYPE_TYPE
Gda::ValueType constant?
:Gda::Value#TYPE_UINTEGER
UINT2NUM()
:Gda::Value#TYPE_UNKNOWN
rb_raise(type-error-of-some-kind) ?
