public class SettingsSchemaKey extends Record
#GSettingsSchemaKey is an opaque data structure and can only be accessed
using the following functions.

https://docs.gtk.org/gio/struct.SettingsSchemaKey.html

  • Konstruktordetails

  • Methodendetails

    • getClassHandler

      public static ClassHandler getClassHandler()

    • getDefaultValue

      public Variant getDefaultValue()
      Gets the default value for @key.

      Note that this is the default value according to the schema. System
      administrator defaults and lockdown are not visible via this API.
      Gibt zurück:
      the default value for the key

    • getDescription

      public Str getDescription()
      Gets the description for @key.

      If no description has been provided in the schema for @key, returns
      %NULL.

      The description can be one sentence to several paragraphs in length.
      Paragraphs are delimited with a double newline. Descriptions can be
      translated and the value returned from this function is is the
      current locale.

      This function is slow. The summary and description information for
      the schemas is not stored in the compiled schema database so this
      function has to parse all of the source XML files in the schema
      directory.
      Gibt zurück:
      the description for @key, or %NULL

    • getName

      public Str getName()
      Gets the name of @key.
      Gibt zurück:
      the name of @key.

    • getRange

      public Variant getRange()
      Queries the range of a key.

      This function will return a #GVariant that fully describes the range
      of values that are valid for @key.

      The type of #GVariant returned is `(sv)`. The string describes
      the type of range restriction in effect. The type and meaning of
      the value contained in the variant depends on the string.

      If the string is `'type'` then the variant contains an empty array.
      The element type of that empty array is the expected type of value
      and all values of that type are valid.

      If the string is `'enum'` then the variant contains an array
      enumerating the possible values. Each item in the array is
      a possible valid value and no other values are valid.

      If the string is `'flags'` then the variant contains an array. Each
      item in the array is a value that may appear zero or one times in an
      array to be used as the value for this key. For example, if the
      variant contained the array `['x', 'y']` then the valid values for
      the key would be `[]`, `['x']`, `['y']`, `['x', 'y']` and
      `['y', 'x']`.

      Finally, if the string is `'range'` then the variant contains a pair
      of like-typed values -- the minimum and maximum permissible values
      for this key.

      This information should not be used by normal programs. It is
      considered to be a hint for introspection purposes. Normal programs
      should already know what is permitted by their own schema. The
      format may change in any way in the future -- but particularly, new
      forms may be added to the possibilities described above.

      You should free the returned value with g_variant_unref() when it is
      no longer needed.
      Gibt zurück:
      a #GVariant describing the range

    • getSummary

      public Str getSummary()
      Gets the summary for @key.

      If no summary has been provided in the schema for @key, returns
      %NULL.

      The summary is a short description of the purpose of the key; usually
      one short sentence. Summaries can be translated and the value
      returned from this function is is the current locale.

      This function is slow. The summary and description information for
      the schemas is not stored in the compiled schema database so this
      function has to parse all of the source XML files in the schema
      directory.
      Gibt zurück:
      the summary for @key, or %NULL

    • getValueType

      public VariantType getValueType()
      Gets the #GVariantType of @key.
      Gibt zurück:
      the type of @key

    • rangeCheck

      public boolean rangeCheck(@Nonnull Variant value)
      Checks if the given @value is within the
      permitted range for @key.

      It is a programmer error if @value is not of the correct type — you
      must check for this first.
      Parameter:
      value - the value to check
      Gibt zurück:
      %TRUE if @value is valid for @key

    • ref

      public SettingsSchemaKey ref()
      Increase the reference count of @key, returning a new reference.
      Gibt zurück:
      a new reference to @key

    • unref

      public void unref()
      Decrease the reference count of @key, possibly freeing it.

    • getTypeID

      public static long getTypeID()

    • getParentTypeID

      public static long getParentTypeID()

    • getTypeSize

      public static TypeSystem.TypeSize getTypeSize()

    • getParentTypeSize

      public static TypeSystem.TypeSize getParentTypeSize()

    • getInstanceSize

      public static int getInstanceSize()
