方法详细资料

add

public abstract FractionScheduler add(int containerComponentId,
                                      Fraction fraction)

Adds a specified Fraction to the container identified by the given containerComponentId.

参数:

containerComponentId - Identifies the container where the Fraction instance will be added.

fraction - Indicates the Fraction instance to add.

返回:

Returns the FractionScheduler instance used to perform the Fraction transaction.

add

public abstract FractionScheduler add(int containerComponentId,
                                      Fraction fraction,
                                      String tag)

Adds a specified Fraction to the container identified by the given containerComponentId and sets the given tag as the unified external identifier of the Fraction instance.

参数:

containerComponentId - Identifies the container where the Fraction instance will be added.

fraction - Indicates the Fraction instance to add.

tag - Indicates the unified identifier to set for the Fraction instance.

返回:

Returns the FractionScheduler instance used to perform the Fraction transaction.

replace

public abstract FractionScheduler replace(int containerComponentId,
                                          Fraction fraction)

Replaces a specified Fraction instance in the container identified by the given containerComponentId.

If the specified Fraction already exists in the container, this method will replace it. Otherwise, this method is equivalent to the add operation.

参数:

containerComponentId - Identifies the container where the Fraction instance will be replaced.

fraction - Indicates the Fraction instance to replace.

返回:

Returns the FractionScheduler instance used to perform the Fraction transaction.

从以下版本开始:

4

remove

public abstract FractionScheduler remove(Fraction fraction)

Removes a specified Fraction instance.

参数:

fraction - Indicates the Fraction instance to remove.

返回:

Returns the FractionScheduler instance used to perform the Fraction transaction.

从以下版本开始:

4

hide

public abstract FractionScheduler hide(Fraction fraction)

Hides a specified Fraction instance.

参数:

fraction - Indicates the Fraction instance to hide.

返回:

Returns the FractionScheduler instance used to perform the Fraction transaction.

从以下版本开始:

4

show

public abstract FractionScheduler show(Fraction fraction)

Shows a specified Fraction instance.

参数:

fraction - Indicates the Fraction instance to show.

返回:

Returns the FractionScheduler instance used to perform the Fraction transaction.

从以下版本开始:

4

submit

public abstract int submit()

Submits this Fraction transaction for performing Fraction lifecycle-related operations.

返回:

Returns the index of this Fraction transaction after it is added to the stack; returns a negative value if pushIntoStack(java.lang.String) was not called.

从以下版本开始:

4

pushIntoStack

public abstract FractionScheduler pushIntoStack(String tag)

Adds this Fraction transaction to the stack and adds a specified name for it.

参数:

tag - Indicates the name of the Fraction transaction to add after it is added to the stack, which can also be null.

返回:

Returns the FractionScheduler instance used to perform the Fraction transaction.
