.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This module represents Dlf field's specifications. You'll get
reference to this kind of object when you call the \fIfield()\fR,
\&\fItimestamp_field()\fR or \fIfields()\fR methods on a \fILire::DlfSchema\fR\|(3pm)
object. You can obtain information about this field by querying its
methods.
.SH "OBJECT METHODS"
.IX Header "OBJECT METHODS"
.SS "\fIname()\fP"
.IX Subsection "name()"
Returns the name of the field.
.SS "\fIlabel()\fP"
.IX Subsection "label()"
Returns the default label that should be used for column containing
values from this field.
.SS "\fIpos()\fP"
.IX Subsection "pos()"
Returns the field's position in the record. Field's positions are
indexed from 0.
.SS "\fItype()\fP"
.IX Subsection "type()"
Returns the field's type. This will be a string describing the type's
name as used in the \s-1XML\s0 specifications.
.SS "\fIsql_type()\fP"
.IX Subsection "sql_type()"
Returns the \s-1SQL\s0 type that should be used to hold this field's values.
.SS "\fIdefault()\fP"
.IX Subsection "default()"
This method is obsolete since field don't have default anymore.
.SS "\fIdescription()\fP"
.IX Subsection "description()"
This method will return the field's description. (This is the content
of the description element in the \s-1XML\s0 specification.) Be aware that
this will most likely contains DocBook markup.
