Class ExecutionContext.ApplicationData

java.lang.Object

com.vmware.vapi.core.ExecutionContext.ApplicationData

Enclosing class:

ExecutionContext

public static class ExecutionContext.ApplicationData
extends java.lang.Object

Immutable class representing additional application specific data associated with the request for method execution represented by this ExecutionContext.

The application data format is key-value pairs of Strings.

This application data is provided by the client initiating the execution, it is then transported as is over the wire and is available for the provider-side service implementations on the server. This extra data is completely opaque for the infrastructure, in other words it is a contract between the client and the service implementation only.

ACCEPT_LANGUAGE_KEY

public static final java.lang.String ACCEPT_LANGUAGE_KEY

FORMAT_LOCALE_KEY

public static final java.lang.String FORMAT_LOCALE_KEY

ApplicationData formatting locale property key.

Optional parameter following the format of the HTTP 1.1 Accept-Language header (RFC 7231 section 5.3.5) used for overriding the value format locale. When missing, implementations will fall back to the accept-language parameter.

If both parameters are missing, locale neutral formatting should be applied i.e. short date to use "yyyy-MM-dd".

Constructor Detail

ApplicationData

public ApplicationData()

Constructs an empty instance.

ApplicationData

public ApplicationData(java.util.Map<java.lang.String,java.lang.String> data)

Constructs an instance with the specified data as a source.

Parameters:

data - key-value entries

Throws:

java.lang.NullPointerException - if data is null

ApplicationData

public ApplicationData(java.lang.String key,
                       java.lang.String value)

Constructs an instance with a single property only.

Parameters:

key - the key of the property

value - the value of the property

Method Detail

getProperty

public java.lang.String getProperty(java.lang.String key)

Parameters:

key - of the property

Returns:

value for the specified key or null if it is unavailable

getAllProperties

public java.util.Map<java.lang.String,java.lang.String> getAllProperties()

Returns:

an immutable Map representing all the properties; cannot be null

merge

public static ExecutionContext.ApplicationData merge(ExecutionContext.ApplicationData source,
                                                     java.util.Map<java.lang.String,java.lang.String> data)

Merges the specified source and data into a newly created ApplicationData instance. Any conflicts are resolved in favor of the specified data.

Parameters:

source - the source of data; may be null

data - a collection of properties to merge with the source

Returns:

a new instance of ApplicationData combining the specified source and data

Throws:

java.lang.NullPointerException - if data is null

merge

public static ExecutionContext.ApplicationData merge(ExecutionContext.ApplicationData source,
                                                     java.lang.String key,
                                                     java.lang.String value)

Merges the specified source and property into a newly created ApplicationData instance. The specified value will override the previous one, if a property with the specified key is already present in the source.

Parameters:

source - the source of data; may be null

key - the key of the property to merge with the source

value - the value of the property to merge with the source

Returns:

a new instance of ApplicationData combining the specified source and property
