詳解

A Wrapper class for Variant values. A method on DBus can send or receive a Variant. This will wrap another value whose type is determined at runtime. The Variant may be parameterized to restrict the types it may accept.

構築子と解体子

Variant() [1/3]

org.freedesktop.dbus.Variant< T >.Variant ( T  o ) throws IllegalArgumentException

inline

Create a Variant from a basic type object.

引数

o	The wrapped value.

例外

IllegalArugmentException

If you try and wrap Null or an object of a non-basic type.

                                                        {
        if (null == o) throw new IllegalArgumentException(getString("cannotWrapNullInVariant"));
        type = o.getClass();
        try {
            String[] ss = Marshalling.getDBusType(o.getClass(), true);
            if (ss.length != 1)
                throw new IllegalArgumentException(getString("cannotWrapMultiValuedInVariant") + type);
            this.sig = ss[0];
        } catch (DBusException DBe) {
            if (AbstractConnection.EXCEPTION_DEBUG && Debug.debug) Debug.print(Debug.ERR, DBe);
            throw new IllegalArgumentException(MessageFormat.format(getString("cannotWrapUnqualifiedVariant"), new Object[]{o.getClass(), DBe.getMessage()}));
        }
        this.o = o;
    }

Variant() [2/3]

org.freedesktop.dbus.Variant< T >.Variant ( T  o, Type  type  ) throws IllegalArgumentException

inline

Create a Variant.

引数

o	The wrapped value.
type	The explicit type of the value.

例外

IllegalArugmentException

If you try and wrap Null or an object which cannot be sent over DBus.

                                                                   {

        this.type = type;
        try {
            String[] ss = Marshalling.getDBusType(type);
            if (ss.length != 1)
                throw new IllegalArgumentException(getString("cannotWrapMultiValuedInVariant") + type);
            this.sig = ss[0];
        } catch (DBusException DBe) {
            if (AbstractConnection.EXCEPTION_DEBUG && Debug.debug) Debug.print(Debug.ERR, DBe);
            throw new IllegalArgumentException(MessageFormat.format(getString("cannotWrapUnqualifiedVariant"), new Object[]{type, DBe.getMessage()}));
        }
        this.o = o;
    }

Variant() [3/3]

org.freedesktop.dbus.Variant< T >.Variant ( T  o, String  sig  ) throws IllegalArgumentException

inline

Create a Variant.

引数

o	The wrapped value.
sig	The explicit type of the value, as a dbus type string.

例外

IllegalArugmentException

If you try and wrap Null or an object which cannot be sent over DBus.

                                                                    {
        if (null == o) throw new IllegalArgumentException(getString("cannotWrapNullInVariant"));
        this.sig = sig;
        try {
            Vector<Type> ts = new Vector<Type>();
            Marshalling.getJavaType(sig, ts, 1);
            if (ts.size() != 1)
                throw new IllegalArgumentException(getString("cannotWrapNoTypesInVariant") + sig);
            this.type = ts.get(0);
        } catch (DBusException DBe) {
            if (AbstractConnection.EXCEPTION_DEBUG && Debug.debug) Debug.print(Debug.ERR, DBe);
            throw new IllegalArgumentException(MessageFormat.format(getString("cannotWrapUnqualifiedVariant"), new Object[]{sig, DBe.getMessage()}));
        }
        this.o = o;
    }

関数詳解

equals()

boolean org.freedesktop.dbus.Variant< T >.equals ( Object  other )

inline

Compare this Variant with another by comparing contents

                                        {
        if (null == other) return false;
        if (!(other instanceof Variant)) return false;
        return this.o.equals(((Variant<? extends Object>) other).o);
    }

getSig()

String org.freedesktop.dbus.Variant< T >.getSig ( )

inline

Return the dbus signature of the wrapped value.

                           {
        return sig;
    }

getType()

Type org.freedesktop.dbus.Variant< T >.getType ( )

inline

                          {
        return type;
    }

getValue()

T org.freedesktop.dbus.Variant< T >.getValue ( )
