Method Detail

getSimpleType

public static SimpleType getSimpleType(Class<?> c)

Get the SimpleType for a class which can be so-represented.

newArrayType

public static ArrayType newArrayType(int numItems,
                                     OpenType type)
                              throws OpenDataException

Exists to avoid warnings from multiple call sites. JMX in JDK 1.5 does not have generic types for JMX, but does in JDK 1.6. This makes it impossible to use generics so long as we're compiling with 1.5. It also means we'll get warnings in JDK 1.6!

Throws:

OpenDataException

getOpenType

public static OpenType getOpenType(Object o)
                            throws InvalidOpenTypeException,
                                   OpenDataException

Get the OpenType of an Object, which must conform to OpenType requirements.

Throws:

InvalidOpenTypeException

OpenDataException

convertTypes

public static Map<String,Serializable> convertTypes(Map<String,Serializable> orig)

Convert certain types and return a new Map:

• Collection converts to an array

Nulls are not eliminated.

mapToCompositeType

public static CompositeType mapToCompositeType(String typeName,
                                               String description,
                                               Map<String,?> map,
                                               CompositeTypeFromNameCallback callback)
                                        throws OpenDataException

Create a CompositeType from a Map. Each key in the map must be a String, and each value must be a type consistent with OpenTypes.

Parameters:

typeName - the arbitrary name of the OpenType to be used

description - the arbitrary description of the OpenType to be used

map - a Map keyed by String, whose values may not be null

Throws:

OpenDataException

mapToCompositeData

public static CompositeData mapToCompositeData(String typeName,
                                               String description,
                                               Map<String,Object> map)
                                        throws OpenDataException

Create a CompositeData from a Map. Each key in the map must be a String, and each value must be a type consistent with OpenTypes.

Parameters:

typeName - the arbitrary name of the OpenType to be used

description - the arbitrary description of the OpenType to be used

map - a Map keyed by String, whose values may not be null

Throws:

OpenDataException

compositeDataToMap

public static Map<String,Serializable> compositeDataToMap(CompositeData data)

Convert a CompositeData to a Map.

getStackTraceElementOpenType

public static OpenType getStackTraceElementOpenType()
                                             throws OpenDataException

Get a CompositeType describing a CompositeData which has no elements.

Throws:

OpenDataException

getThrowableOpenType
