Constructs an OpenMBeanAttributeInfoSupport instance,
which describes the attribute of an open MBean with the
specified name, openType and description, and the specified read/write access properties.
Parameters:
- name - cannot be a null or empty string.
- description - cannot be a null or empty string.
- openType - cannot be null.
- isReadable - {@code true} if the attribute has a getter exposed for management.
- isWritable - {@code true} if the attribute has a setter exposed for management.
- isIs - {@code true} if the attribute's getter is of the form isXXX.
Throws:
- IllegalArgumentException - if {@code name} or {@code description} are null or empty string, or {@code openType} is null.

public OpenMBeanAttributeInfoSupport (String name, String description, OpenType<Object> openType, boolean isReadable, boolean isWritable, boolean isIs, Descriptor descriptor)

Constructs an OpenMBeanAttributeInfoSupport instance, which describes the attribute of an open MBean with the specified name, openType, description, read/write access properties, and Descriptor.

public OpenMBeanAttributeInfoSupport (String name, String description, OpenType< T> openType, boolean isReadable, boolean isWritable, boolean isIs, T defaultValue) throws OpenDataException

Constructs an OpenMBeanAttributeInfoSupport instance,
which describes the attribute of an open MBean with the
specified name, openType, description
and defaultValue, and the specified read/write access
properties.
Parameters:
- name - cannot be a null or empty string.
- description - cannot be a null or empty string.
- openType - cannot be null.
- isReadable - {@code true} if the attribute has a getter exposed for management.
- isWritable - {@code true} if the attribute has a setter exposed for management.
- isIs - {@code true} if the attribute's getter is of the form isXXX.
- defaultValue - must be a valid value for the {@code openType} specified for this attribute; default value not supported for {@code ArrayType} and {@code TabularType}; can be null, in which case it means that no default value is set.
- T - allows the compiler to check that the {@code defaultValue}, if non-null, has the correct Java type for the given {@code openType}.
Throws:
- IllegalArgumentException - if {@code name} or {@code description} are null or empty string, or {@code openType} is null.
- OpenDataException - if {@code defaultValue} is not a valid value for the specified {@code openType}, or {@code defaultValue} is non null and {@code openType} is an {@code ArrayType} or a {@code TabularType}.

public OpenMBeanAttributeInfoSupport (String name, String description, OpenType< T> openType, boolean isReadable, boolean isWritable, boolean isIs, T defaultValue, Comparable< T> minValue, Comparable< T> maxValue) throws OpenDataException

Constructs an OpenMBeanAttributeInfoSupport instance,
which describes the attribute of an open MBean, with the
specified name, openType, description,

It is possible to specify minimal and maximal values only for
an open type whose values are Comparable.
Parameters:
- name - cannot be a null or empty string.
- description - cannot be a null or empty string.
- openType - cannot be null.
- isReadable - {@code true} if the attribute has a getter exposed for management.

- isIs - {@code true} if the attribute's getter is of the form isXXX.
- defaultValue - must be a valid value for the {@code openType} specified for this attribute; default value not supported for {@code ArrayType} and {@code TabularType}; can be null, in which case it means that no default value is set.
- minValue - must be valid for the {@code openType} specified for this attribute; can be null, in which case it means that no minimal value is set.
- maxValue - must be valid for the {@code openType} specified for this attribute; can be null, in which case it means that no maximal value is set.
- T - allows the compiler to check that the {@code defaultValue}, {@code minValue}, and {@code maxValue}, if non-null, have the correct Java type for the given {@code openType}.
Throws:
- IllegalArgumentException - if {@code name} or {@code description} are null or empty string, or {@code openType} is null.
- OpenDataException - if {@code defaultValue}, {@code minValue} or {@code maxValue} is not a valid value for the specified {@code openType}, or {@code defaultValue} is non null and {@code openType} is an {@code ArrayType} or a {@code TabularType}, or both {@code minValue} and {@code maxValue} are non-null and {@code minValue.compareTo(maxValue) > 0} is {@code true}, or both {@code defaultValue} and {@code minValue} are non-null and {@code minValue.compareTo(defaultValue) > 0} is {@code true}, or both {@code defaultValue} and {@code maxValue} are non-null and {@code defaultValue.compareTo(maxValue) > 0} is {@code true}.

Constructs an OpenMBeanAttributeInfoSupport instance, which describes the attribute of an open MBean with the specified name, openType, description, defaultValue and legalValues, and the specified read/write access properties.

Methods

Hide/Show inherited methods

pack-privatestatic void check (OpenMBeanParameterInfo info) throws OpenDataException

public Object clone () [Inherited From MBeanAttributeInfo]

Returns a shallow clone of this instance.

pack-privatestatic Comparable comparableValueFrom (Descriptor d, String name, OpenType< T> openType)

pack-privatestatic boolean equal (OpenMBeanParameterInfo x1, OpenMBeanParameterInfo x2)

public boolean equals (Object obj) [Overrides MBeanAttributeInfo] [Specified in OpenMBeanAttributeInfo]

Compares the specified obj parameter with this OpenMBeanAttributeInfoSupport instance for equality.

Returns true if and only if all of the following statements are true:

obj is non null,
obj also implements the OpenMBeanAttributeInfo interface,
their names are equal
their open types are equal
their access properties (isReadable, isWritable and isIs) are equal
their default, min, max and legal values are equal.

This ensures that this equals method works properly for obj parameters which are different implementations of the OpenMBeanAttributeInfo interface.

If obj also implements DescriptorRead, then its getDescriptor() method must also return the same value as for this object.

Returns: {@code true} if the specified object is equal to this {@code OpenMBeanAttributeInfoSupport} instance.
Parameters:
- obj - the object to be compared for equality with this {@code OpenMBeanAttributeInfoSupport} instance.

public Object getDefaultValue ()

Returns the default value for the attribute described by this OpenMBeanAttributeInfoSupport instance, if specified, or null otherwise.

public String getDescription () [Inherited From MBeanFeatureInfo]

public String toString () [Overrides MBeanAttributeInfo] [Specified in OpenMBeanAttributeInfo]

Returns a string representation of this OpenMBeanAttributeInfoSupport instance.

The string representation consists of the name of this class (i.e. javax.management.openmbean.OpenMBeanAttributeInfoSupport), the string representation of the name and open type of the described parameter, the string representation of its default, min, max and legal values and the string representation of its descriptor.

As OpenMBeanAttributeInfoSupport instances are immutable, the string representation for this instance is calculated once, on the first call to toString, and then the same value is returned for subsequent calls.
