方法详细资料

write

public final void write(ChartOuterClass.ChartOrBuilder chartBuilder)
                 throws IOException

Writes or serializes or otherwise represents the supplied ChartOuterClass.ChartOrBuilder.

参数:

chartBuilder - the ChartOuterClass.ChartOrBuilder to write; must not be null

抛出:

IOException - if a write error occurs

NullPointerException - if chartBuilder is null

IllegalArgumentException - if the ChartOuterClass.ChartOrBuilder.getMetadata() method returns null, or if the MetadataOuterClass.MetadataOrBuilder.getName() method returns null, or if the MetadataOuterClass.MetadataOrBuilder.getVersion() method returns null

IllegalStateException - if a subclass has overridden the createYaml() method to return null and calls it

write(Context, ChartOuterClass.ChartOrBuilder, ChartOuterClass.ChartOrBuilder)

write

protected void write(AbstractChartWriter.Context context,
                     ChartOuterClass.ChartOrBuilder parent,
                     ChartOuterClass.ChartOrBuilder chartBuilder)
              throws IOException

Writes or serializes or otherwise represents the supplied chartBuilder as a subchart of the supplied parent (which may be, and often is, null).

参数:

context - the AbstractChartWriter.Context representing the write operation; may be null

parent - the ChartOuterClass.ChartOrBuilder functioning as the parent chart; may be, and often is, null; must not be identical to the chartBuilder parameter value

chartBuilder - the ChartOuterClass.ChartOrBuilder to actually write; must not be null; must not be identical to the parent parameter value

抛出:

IOException - if a write error occurs

NullPointerException - if chartBuilder is null

IllegalArgumentException - if parent is identical to chartBuilder, or if the ChartOuterClass.ChartOrBuilder.getMetadata() method returns null, or if the MetadataOuterClass.MetadataOrBuilder.getName() method returns null, or if the MetadataOuterClass.MetadataOrBuilder.getVersion() method returns null

IllegalStateException - if a subclass has overridden the createYaml() method to return null and calls it

createYaml

protected org.yaml.snakeyaml.Yaml createYaml()

Creates and returns a new Yaml instance for (optional) use in writing ConfigOuterClass.ConfigOrBuilder and MetadataOuterClass.MetadataOrBuilder objects.

This method never returns null.

Overrides of this method must not return null.

Behavior is undefined if overrides of this method interact with other methods defined by this class.

返回:

a non-null Yaml instance

toYAML

protected final String toYAML(AbstractChartWriter.Context context,
                              Object data)
                       throws IOException

Marshals the supplied Object to YAML in the context of the supplied AbstractChartWriter.Context and returns the result.

This method never returns null.

This method may call the createYaml() method.

参数:

context - the AbstractChartWriter.Context representing the write operation; must not be null

data - the Object to convert to its YAML representation; may be null

返回:

a non-null String consisting of the appropriate YAML represesentation of the supplied data

抛出:

IOException - if a YAML serialization error occurs

NullPointerException - if context is null

A callback method invoked when the write(Context, ChartOuterClass.ChartOrBuilder, ChartOuterClass.ChartOrBuilder) method has been invoked and it is time to write a relevant MetadataOuterClass.MetadataOrBuilder object.

参数:

context - the AbstractChartWriter.Context representing the write operation; must not be null

metadata - the MetadataOuterClass.MetadataOrBuilder to write; must not be null
