Constructor Detail

public OperaScopePreferences.ScopePreference(OperaScopePreferences parent,
                                             PrefsProtos.Pref pref)

Method Detail

getValue

public Object getValue()

Gets the value of the preference in an idiomatic type. We fall back to String if no type is specified for this preference.

Specified by:

getValue in interface OperaPreferences.OperaPreference

Overrides:

getValue in class AbstractOperaPreferences.AbstractPreference

Returns:

the value of the string, as an idiomatic Java type

setValue

public void setValue(Object value)

Description copied from interface: OperaPreferences.OperaPreference

Sets the value of this preference.

Specified by:

setValue in interface OperaPreferences.OperaPreference

Overrides:

setValue in class AbstractOperaPreferences.AbstractPreference

Parameters:

value - the new value

getDefaultValue

public Object getDefaultValue()

Description copied from interface: OperaPreferences.OperaPreference

Gets the default value of the preference.

Specified by:

getDefaultValue in interface OperaPreferences.OperaPreference

Overrides:

getDefaultValue in class AbstractOperaPreferences.AbstractPreference

Returns:

the default value of this preference

getType

public Type getType()

Gets the type of the preference. Since Opera uses more internal field types than what is accessible to Java, we reduce the type specified by Opera (in a lossy way) to one of either Boolean, OperaColor, File, Integer or String.

Returns:

the idiomatic Java type for this preference

isEnabled

public boolean isEnabled()

Whether setting is overriden by global INI. If this value is missing, it means global INI is not supported.

Returns:

true if enabled, false otherwise

reset

public void reset()

Resets preference's value to its default value. This method is a short-hand method for doing preference.setValue(preference.getDefaultValue).
