javax.management.openmbean.OpenType<T>
- Type Parameters:
T- the Java type that instances described by this type must have. For example,SimpleType.INTEGERis aSimpleType<Integer>which is a subclass ofOpenType<Integer>, meaning that an attribute, parameter, or return value that is described as aSimpleType.INTEGERmust have Java typeInteger.
- All Implemented Interfaces:
Serializable
- Direct Known Subclasses:
ArrayType,CompositeType,SimpleType,TabularType
The
OpenType class is the parent abstract class of all classes which describe the actual open type
of open data values.
An open type is defined by:
- the fully qualified Java class name of the open data values this type describes;
note that only a limited set of Java classes is allowed for open data values
(see
ALLOWED_CLASSNAMES_LIST), - its name,
- its description.
- Since:
- 1.5

ALLOWED_CLASSNAMES_LIST
List of the fully qualified names of the Java classes allowed for open data values. A multidimensional array of any one of these classes or their corresponding primitive types is also an allowed class for open data values.ALLOWED_CLASSNAMES_LIST = { "java.lang.Void", "java.lang.Boolean", "java.lang.Character", "java.lang.Byte", "java.lang.Short", "java.lang.Integer", "java.lang.Long", "java.lang.Float", "java.lang.Double", "java.lang.String", "java.math.BigDecimal", "java.math.BigInteger", "java.util.Date", "javax.management.ObjectName", CompositeData.class.getName(), TabularData.class.getName() } ; -

OpenType
Constructs anOpenTypeinstance (actually a subclass instance asOpenTypeis abstract), checking for the validity of the given parameters. The validity constraints are described below for each parameter.
- Parameters:
className- The fully qualified Java class name of the open data values this open type describes. The valid Java class names allowed for open data values are listed inALLOWED_CLASSNAMES_LIST. A multidimensional array of any one of these classes or their corresponding primitive types is also an allowed class, in which case the class name follows the rules defined by the methodgetName()ofjava.lang.Class. For example, a 3-dimensional array of Strings has for class name "[[[Ljava.lang.String;" (without the quotes).
typeName- The name given to the open type this instance represents; cannot be a null or empty string.
description- The human readable description of the open type this instance represents; cannot be a null or empty string.
- Throws:
IllegalArgumentException- if className, typeName or description is a null or empty string
OpenDataException- if className is not one of the allowed Java class names for open data

getClassName
Returns the fully qualified Java class name of the open data values this open type describes. The only possible Java class names for open data values are listed inALLOWED_CLASSNAMES_LIST. A multidimensional array of any one of these classes or their corresponding primitive types is also an allowed class, in which case the class name follows the rules defined by the methodgetName()ofjava.lang.Class. For example, a 3-dimensional array of Strings has for class name "[[[Ljava.lang.String;" (without the quotes), a 3-dimensional array of Integers has for class name "[[[Ljava.lang.Integer;" (without the quotes), and a 3-dimensional array of int has for class name "[[[I" (without the quotes)- Returns:
- the class name.
-
getTypeName
Returns the name of thisOpenTypeinstance.- Returns:
- the type name.
-
getDescription
Returns the text description of thisOpenTypeinstance.- Returns:
- the description.
-
isArray
public boolean isArray()Returnstrueif the open data values this open type describes are arrays,falseotherwise.- Returns:
- true if this is an array type.
-
isValue
Tests whether obj is a value for this open type.- Parameters:
obj- the object to be tested for validity.- Returns:
trueif obj is a value for this open type,falseotherwise.
-
equals
Compares the specifiedobjparameter with this open type instance for equality. -
hashCode
public abstract int hashCode()Description copied from class:ObjectAnswers an integer hash code for the receiver. Any two objects which answertruewhen passed to.equalsmust answer the same value for this method. -
toString
Returns a string representation of this open type instance.
