class PG::CopyCoder
This is the base class for all type cast classes for COPY data,
Public Instance Methods
The character that separates columns within each row (line) of the file.
static VALUE pg_copycoder_delimiter_get(VALUE self) { t_pg_copycoder *this = DATA_PTR(self); return rb_str_new(&this->delimiter, 1); }
Specifies the character that separates columns within each row (line) of the file. The default is a tab character in text format, a comma in CSV format. This must be a single one-byte character. This option is ignored when using binary format.
static VALUE pg_copycoder_delimiter_set(VALUE self, VALUE delimiter) { t_pg_copycoder *this = DATA_PTR(self); StringValue(delimiter); if(RSTRING_LEN(delimiter) != 1) rb_raise( rb_eArgError, "delimiter size must be one byte"); this->delimiter = *RSTRING_PTR(delimiter); return delimiter; }
The string that represents a null value.
static VALUE pg_copycoder_null_string_get(VALUE self) { t_pg_copycoder *this = DATA_PTR(self); return this->null_string; }
Specifies the string that represents a null value. The default is \N (backslash-N) in text format, and an unquoted empty string in CSV format. You might prefer an empty string even in text format for cases where you don't want to distinguish nulls from empty strings. This option is ignored when using binary format.
static VALUE pg_copycoder_null_string_set(VALUE self, VALUE null_string) { t_pg_copycoder *this = DATA_PTR(self); StringValue(null_string); this->null_string = null_string; return null_string; }

The PG::TypeMap
that will be used for encoding and decoding of columns.
static VALUE pg_copycoder_type_map_get(VALUE self) { t_pg_copycoder *this = DATA_PTR( self ); return this->typemap; }
Defines how single columns are encoded or decoded. map
must be a kind of PG::TypeMap
.
Defaults to a PG::TypeMapAllStrings
, so that PG::TextEncoder::String
respectively PG::TextDecoder::String
is used for encoding/decoding of each column.
static VALUE pg_copycoder_type_map_set(VALUE self, VALUE type_map) { t_pg_copycoder *this = DATA_PTR( self ); if ( !rb_obj_is_kind_of(type_map, rb_cTypeMap) ){ rb_raise( rb_eTypeError, "wrong elements type %s (expected some kind of PG::TypeMap)", rb_obj_classname( type_map ) ); } this->typemap = type_map; return type_map; }
