toNamedInputStreamEntries

protected abstract Iterable<? extends Map.Entry<? extends String,? extends InputStream>> toNamedInputStreamEntries(T source)
                                                                                                                  throws IOException

Converts the supplied source into an Iterable of Map.Entry instances whose keys are names and whose values are corresponding InputStreams.

Implementations of this method must not return null.

The Iterable of Map.Entry instances returned by implementations of this method must produce an Iterator that will never return null from any invocation of its Iterator.next() method when, on the same thread, the return value of an invocation of its Iterator.hasNext() method has previously returned true.

Map.Entry instances returned by Iterator instances produced by the Iterable returned by this method must never return null from their Map.Entry.getKey() method. They are permitted to return null from their Map.Entry.getValue() method, and this feature can be used, for example, to indicate that a particular entry is a directory.

参数:

source - the source to convert; must not be null

返回:

an Iterable of suitable Map.Entry instances; never null

抛出:

NullPointerException - if source is null

IOException - if an error occurs while converting

load

public ChartOuterClass.Chart.Builder load(ChartOuterClass.Chart.Builder parent,
                                          T source,
                                          String valueFileName)
                                   throws IOException

Creates a new ChartOuterClass.Chart from the supplied source in some manner and returns it.

This method never returns null.

指定者:

load 在类中 AbstractChartLoader<T>

参数:

source - the source object from which to load a new ChartOuterClass.Chart; must not be null

valueFileName - the value filename

parent - the ChartOuterClass.Chart.Builder that will serve as the parent of the ChartOuterClass.Chart.Builder that will be returned; may be (and often is) null, indicating that the ChartOuterClass.Chart.Builder being returned does not represent a subchart; must not be what is returned

返回:

a new ChartOuterClass.Chart; never null

抛出:

NullPointerException - if source is null

IllegalStateException

IOException - if a problem is encountered while creating the ChartOuterClass.Chart to return

load

public ChartOuterClass.Chart.Builder load(ChartOuterClass.Chart.Builder parent,
                                          Iterable<? extends Map.Entry<? extends String,? extends InputStream>> entrySet,
                                          String valueFileName)
                                   throws IOException

Creates a new ChartOuterClass.Chart from the supplied notional set of named InputStreams and returns it.

This method never returns null.

This method is called by the AbstractChartLoader.load(Object) method.

参数:

entrySet - the Iterable of Map.Entry instances normally returned by the toNamedInputStreamEntries(Object) method; must not be null

返回:

a new ChartOuterClass.Chart; never null

抛出:

NullPointerException - if entrySet is null

IOException - if a problem is encountered while creating the ChartOuterClass.Chart to return

installConfig

protected void installConfig(ChartOuterClass.Chart.Builder chartBuilder,
                             InputStream stream)
                      throws IOException

Installs a ConfigOuterClass.Config object, represented by the supplied InputStream, into the supplied Chart.Builder.

参数:

chartBuilder - the Chart.Builder to affect; must not be null

stream - an InputStream representing valid values file contents as defined by the chart specification; must not be null

抛出:

NullPointerException - if chartBuilder or stream is null

IOException - if there was a problem reading from the supplied InputStream

                        throws IOException

Installs a MetadataOuterClass.Metadata object, represented by the supplied InputStream, into the supplied Chart.Builder.

参数:

chartBuilder - the Chart.Builder to affect; must not be null

stream - an InputStream representing valid Chart.yaml contents as defined by the chart specification; must not be null

抛出:

NullPointerException - if chartBuilder or stream is null

IOException - if there was a problem reading from the supplied InputStream
