AbstractRuntimeProperty

public AbstractRuntimeProperty()

AbstractRuntimeProperty

protected AbstractRuntimeProperty(PropertyDefinition<T> propertyDefinition)

方法详细资料

getPropertyDefinition

public PropertyDefinition<T> getPropertyDefinition()

指定者:

getPropertyDefinition 在接口中 RuntimeProperty<T>

initializeFrom

public void initializeFrom(Properties extractFrom,
                           ExceptionInterceptor exceptionInterceptor)

从接口复制的说明: RuntimeProperty

Explicitly set value of this RuntimeProperty according to the self-titled property value contained in extractFrom. This method is called during PropertySet initialization thus ignores the RUNTIME_NOT_MODIFIABLE flag.

This value will also be the initial one, i.e. RuntimeProperty.resetValue() will reset to this value, not the default one.

If extractFrom does not contain such property then this RuntimeProperty remains unchanged.

指定者:

initializeFrom 在接口中 RuntimeProperty<T>

参数:

extractFrom - Properties object containing key-value pairs usually passed from connection string.

exceptionInterceptor - exceptionInterceptor

initializeFrom

public void initializeFrom(Reference ref,
                           ExceptionInterceptor exceptionInterceptor)

指定者:

initializeFrom 在接口中 RuntimeProperty<T>

resetValue

public void resetValue()

从接口复制的说明: RuntimeProperty

Reset to initial value (default or defined in connection string/Properties)

指定者:

resetValue 在接口中 RuntimeProperty<T>

isExplicitlySet

public boolean isExplicitlySet()

指定者:

isExplicitlySet 在接口中 RuntimeProperty<T>

addListener

public void addListener(RuntimeProperty.RuntimePropertyListener l)

从接口复制的说明: RuntimeProperty

Add listener for this property changes.

指定者:

addListener 在接口中 RuntimeProperty<T>

参数:

l - RuntimeProperty.RuntimePropertyListener

removeListener

public void removeListener(RuntimeProperty.RuntimePropertyListener listener)

指定者:

removeListener 在接口中 RuntimeProperty<T>

invokeListeners

protected void invokeListeners()

getValue

public T getValue()

从接口复制的说明: RuntimeProperty

Get internal value representation as Object.

指定者:

getValue 在接口中 RuntimeProperty<T>

返回:

value

getInitialValue

public T getInitialValue()

从接口复制的说明: RuntimeProperty

Get initial value (default or defined in connection string/Properties)

指定者:

getInitialValue 在接口中 RuntimeProperty<T>

返回:

value

getStringValue

public String getStringValue()

从接口复制的说明: RuntimeProperty

Get internal value representation as String.

指定者:

getStringValue 在接口中 RuntimeProperty<T>

返回:

value

setValueInternal

public void setValueInternal(String value,
                             ExceptionInterceptor exceptionInterceptor)

Set the value of a property from a string value. It involves the PropertyDefinition.parseObject(String, ExceptionInterceptor) to validate and parse the string.

参数:

value - value

exceptionInterceptor - exception interceptor

setValueInternal

public void setValueInternal(T value,
                             String valueAsString,
                             ExceptionInterceptor exceptionInterceptor)

Internal method for setting property value; ignoring the RUNTIME_NOT_MODIFIABLE flag.

参数:

value - value

valueAsString - value represented by String

exceptionInterceptor - exception interceptor

checkRange

protected void checkRange(T val,
                          String valueAsString,
                          ExceptionInterceptor exceptionInterceptor)

For range-based property, checks that value fit into range given by PropertyDefinition.

参数:

val - value

valueAsString - value represented by String

exceptionInterceptor - exception interceptor

setValue

public void setValue(T value)

从接口复制的说明: RuntimeProperty

Set the object value of a property directly. Validation against allowable values will be performed.

指定者:

setValue 在接口中 RuntimeProperty<T>

参数:

value - value

setValue

public void setValue(T value,
                     ExceptionInterceptor exceptionInterceptor)

从接口复制的说明: RuntimeProperty

Set the object value of a property directly. Validation against allowable values will be performed.

指定者:

setValue 在接口中 RuntimeProperty<T>

参数:

value - value

exceptionInterceptor - exception interceptor
