getBindingContext

public IBindingContext getBindingContext()

Description copied from interface: IBoundLoader

Get the configured Module binding context to use to load Java types.

Specified by:

getBindingContext in interface IBoundLoader

Returns:

the binding context

detectFormat

public Format detectFormat(@NonNull
 URI uri)
                    throws IOException

Description copied from interface: IBoundLoader

Determine the format of the resource identified by the provided uri.

Specified by:

detectFormat in interface IBoundLoader

Parameters:

uri - the resource

Returns:

the format information for the provided resource

Throws:

IOException - if an error occurred while reading the resource

detectFormat

public FormatDetector.Result detectFormat(@NonNull
 InputStream is)
                                   throws IOException

Description copied from interface: IBoundLoader

Determine the format of the provided resource.

This method will consume data from the provided InputStream. If the caller of this method intends to read data from the stream after determining the format, the caller should pass in a stream that can be reset.

This method will not close the provided InputStream, since it does not own the stream.

Specified by:

detectFormat in interface IBoundLoader

Parameters:

is - an input stream for the resource

Returns:

the format information for the provided resource

Throws:

IOException - if an error occurred while reading the resource

detectModel

@Owning
public @Owning ModelDetector.Result detectModel(@NotOwning
 InputStream is,
 Format format)
                                         throws IOException

Description copied from interface: IBoundLoader

Determine the model of the provided resource.

This method will consume data from any InputStream provided by the InputSource. If the caller of this method intends to read data from the stream after determining the format, the caller should pass in a stream that can be reset.

This method will not close any InputStream provided by the InputSource, since it does not own the stream.

Specified by:

detectModel in interface IBoundLoader

Parameters:

is - an input stream for the resource

format - the format of the provided resource

Returns:

the model of the provided resource

Throws:

IOException - if an error occurred while reading the resource

load

public <CLASS extends IBoundObject> CLASS load(@NonNull
 URI uri)
                                        throws IOException

Description copied from interface: IBoundLoader

Load data from the resource identified by the provided uri into a bound object.

This method will auto-detect the format of the provided resource.

Specified by:

load in interface IBoundLoader

Type Parameters:

CLASS - the type of the bound object to return

Parameters:

uri - the resource

Returns:

a bound object containing the loaded data

Throws:

IOException - if an error occurred while reading the resource

@NonNull
public <CLASS extends IBoundObject> CLASS load(@NotOwning @NonNull
 InputStream is,
 @NonNull
 URI documentUri)
                                        throws IOException

Description copied from interface: IBoundLoader

Load data from the provided resource into a bound object.

This method should auto-detect the format of the provided resource.

This method will not close the provided InputStream, since it does not own the stream.

Specified by:

load in interface IBoundLoader

Type Parameters:

CLASS - the type of the bound object to return

Parameters:

is - the resource stream

documentUri - the URI of the resource

Returns:

a bound object containing the loaded data

Throws:

IOException - if an error occurred while reading the resource

public <CLASS extends IBoundObject> CLASS load(Class<CLASS> clazz,
 URI uri)
                                        throws IOException

Description copied from interface: IBoundLoader

Load data from the specified resource into a bound object with the type of the specified Java class.

Specified by:

load in interface IBoundLoader

Type Parameters:

CLASS - the Java type to load data into

Parameters:

clazz - the class for the java type

uri - the resource to load

Returns:

the loaded instance data

Throws:

IOException - if an error occurred while loading the data in the specified file

load

public <CLASS extends IBoundObject> CLASS load(Class<CLASS> clazz,
 InputStream is,
 URI documentUri)
                                        throws IOException

Description copied from interface: IBoundLoader

Load data from the specified resource into a bound object with the type of the specified Java class.

This method will not close the provided InputStream, since it does not own the stream.

Implementations of this method will do format detection. This process might leave the provided InputStream at a position beyond the last parsed location. If you want to avoid this possibility, use and implementation of IDeserializer.deserialize(InputStream, URI) instead, such as what is provided by DefaultBindingContext.newDeserializer(Format, Class).

Specified by:

load in interface IBoundLoader

Type Parameters:

CLASS - the Java type to load data into

Parameters:

clazz - the class for the java type

is - the resource stream

documentUri - the URI of the resource

Returns:

the loaded data

Throws:

IOException - if an error occurred while loading the data from the specified resource
