class: GTuples

[30:7] extends: object

The #GTuples struct is used to return records (or tuples) from the #GRelation by g_relation_select(). It only contains one public member - the number of records that matched. To access the matched records, you must use g_tuples_index().

Members

retainedCallbacks
signalHandlerNames
signalSetterHandlers

Methods

GTuples (Handle = null)

Creates a new Tuples by wrapping a native handle or another wrapper.
- @p Handle is the native handle or another wrapper whose handle to adopt.
toNativeHandle (Source)

Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.
- @p Source is the raw handle, raw buffer, wrapper, or null.
- @r A raw pointer carrier or null when no pointer is present.
getLib ()

Returns the opened native library for this generated wrapper.
- @r The opened native library.
handle ()

Returns the wrapped NativeHandle.
- @r The wrapped NativeHandle.
isNull ()

Returns true when the wrapped handle is null.
- @r A bool.
describe ()

Returns a small string for debugging generated wrappers.
- @r A string.
destroy ()

Frees the records which were returned by g_relation_select(). This should always be called after g_relation_select() when you are finished with the records. The records are not removed from the #GRelation.
- @r None.
index (int index_, int field)

Gets a field from the records returned by g_relation_select(). It returns the given field of the record at the given index. The returned value should not be changed.
- @p index_ is the index of the record..
- @p field is the field to return..
- @r the field of the record..

class: GTuplesLayout

Methods
