Class ReaderInterceptorExecutor

java.lang.Object

org.glassfish.jersey.message.internal.ReaderInterceptorExecutor

All Implemented Interfaces:

InterceptorContext, ReaderInterceptorContext, InjectionManagerSupplier, PropertiesDelegate

public final class ReaderInterceptorExecutor
extends Object
implements ReaderInterceptorContext, InjectionManagerSupplier

Represents reader interceptor chain executor for both client and server side. It constructs wrapped interceptor chain and invokes it. At the end of the chain a message body reader execution interceptor is inserted, which finally reads an entity from the output stream provided by the chain.

Method Details

proceed

public Object proceed()
               throws IOException

Starts the interceptor chain execution.

Specified by:

proceed in interface ReaderInterceptorContext

Returns:

an entity read from the stream.

Throws:

IOException

getInputStream

public InputStream getInputStream()

Specified by:

getInputStream in interface ReaderInterceptorContext

setInputStream

public void setInputStream(InputStream is)

Specified by:

setInputStream in interface ReaderInterceptorContext

getHeaders

public MultivaluedMap<String,String> getHeaders()

Specified by:

getHeaders in interface ReaderInterceptorContext

getInjectionManager

public InjectionManager getInjectionManager()

Description copied from interface: InjectionManagerSupplier

Get injection manager.

Specified by:

getInjectionManager in interface InjectionManagerSupplier

Returns:

injection manager.

closeableInputStream

public static InputStream closeableInputStream(InputStream inputStream)

Make the InputStream able to close.

The purpose of this utility method is to undo effect of ReaderInterceptorExecutor.UnCloseableInputStream.

Parameters:

inputStream - Potential ReaderInterceptorExecutor.UnCloseableInputStream to undo its effect

Returns:

Input stream that is possible to close

hasProperty

public boolean hasProperty(String name)

Description copied from interface: PropertiesDelegate

Returns true if the property with the given name registered in the current request/response exchange context, or false if there is no property by that name.

Use the PropertiesDelegate.getProperty(java.lang.String) method with a property name to get the value of a property.

Specified by:

hasProperty in interface InterceptorContext

Specified by:

hasProperty in interface PropertiesDelegate

Returns:

true if a property matching the given name exists, or false otherwise.

See Also:

• PropertiesDelegate.getProperty(java.lang.String)

getProperty

public Object getProperty(String name)

Description copied from interface: PropertiesDelegate

Returns the property with the given name registered in the current request/response exchange context, or null if there is no property by that name.

A property allows a JAX-RS filters and interceptors to exchange additional custom information not already provided by this interface.

A list of supported properties can be retrieved using PropertiesDelegate.getPropertyNames(). Custom property names should follow the same convention as package names.

Specified by:

getProperty in interface InterceptorContext

Specified by:

getProperty in interface PropertiesDelegate

Parameters:

name - a String specifying the name of the property.

Returns:

an Object containing the value of the property, or null if no property exists matching the given name.

See Also:

• PropertiesDelegate.getPropertyNames()

getPropertyNames

public Collection<String> getPropertyNames()

Description copied from interface: PropertiesDelegate

Returns an immutable collection containing the property names available within the context of the current request/response exchange context.

Use the PropertiesDelegate.getProperty(java.lang.String) method with a property name to get the value of a property.

Specified by:

getPropertyNames in interface InterceptorContext

Specified by:

getPropertyNames in interface PropertiesDelegate

Returns:

an immutable collection of property names.

See Also:

• PropertiesDelegate.getProperty(java.lang.String)

setProperty

public void setProperty(String name,
 Object object)

Description copied from interface: PropertiesDelegate

Binds an object to a given property name in the current request/response exchange context. If the name specified is already used for a property, this method will replace the value of the property with the new value.

A property allows a JAX-RS filters and interceptors to exchange additional custom information not already provided by this interface.

A list of supported properties can be retrieved using PropertiesDelegate.getPropertyNames(). Custom property names should follow the same convention as package names.

If a null value is passed, the effect is the same as calling the PropertiesDelegate.removeProperty(String) method.

Specified by:

setProperty in interface InterceptorContext

Specified by:

setProperty in interface PropertiesDelegate

Parameters:

name - a String specifying the name of the property.

object - an Object representing the property to be bound.

removeProperty

public void removeProperty(String name)

Description copied from interface: PropertiesDelegate

Removes a property with the given name from the current request/response exchange context. After removal, subsequent calls to PropertiesDelegate.getProperty(java.lang.String) to retrieve the property value will return null.

Specified by:

removeProperty in interface InterceptorContext

Specified by:

removeProperty in interface PropertiesDelegate

Parameters:

name - a String specifying the name of the property to be removed.

getTracingLogger

protected final TracingLogger getTracingLogger()

Get tracing logger instance configured in via properties.

Returns:

tracing logger instance.

traceBefore

protected final void traceBefore(ReaderInterceptor interceptor,
 TracingLogger.Event event)

Tracing support - log invocation of interceptor BEFORE context.proceed() call.

Parameters:

interceptor - invoked interceptor

event - event type to be tested

traceAfter

protected final void traceAfter(ReaderInterceptor interceptor,
 TracingLogger.Event event)

Tracing support - log invocation of interceptor AFTER context.proceed() call.

Parameters:

interceptor - invoked interceptor

event - event type to be tested

clearLastTracedInterceptor

protected final void clearLastTracedInterceptor()

Clear last traced interceptor information.
