public OpenMBeanParameterInfoSupport(String name, String description, OpenType<?> openType)

Constructs an OpenMBeanParameterInfoSupport instance, which describes the parameter used in one or more operations or constructors of a class of open MBeans, with the specified name, openType and description.

public OpenMBeanParameterInfoSupport(String name, String description, OpenType<?> openType, Descriptor descriptor)

Constructs an OpenMBeanParameterInfoSupport instance, which describes the parameter used in one or more operations or constructors of a class of open MBeans, with the specified name, openType, description, and descriptor.

The descriptor can contain entries that will define the values returned by certain methods of this class, as explained in the package description.

public OpenMBeanParameterInfoSupport(String name, String description, OpenType<T> openType, T defaultValue) throws OpenDataException

Constructs an OpenMBeanParameterInfoSupport instance, which describes the parameter used in one or more operations or constructors of a class of open MBeans, with the specified name, openType, description and defaultValue.

public OpenMBeanParameterInfoSupport(String name, String description, OpenType<T> openType, T defaultValue, T[] legalValues) throws OpenDataException

Constructs an OpenMBeanParameterInfoSupport instance, which describes the parameter used in one or more operations or constructors of a class of open MBeans, with the specified name, openType, description, defaultValue and legalValues.

The contents of legalValues are copied, so subsequent modifications of the array referenced by legalValues have no impact on this OpenMBeanParameterInfoSupport instance.

public OpenMBeanParameterInfoSupport(String name, String description, OpenType<T> openType, T defaultValue, Comparable<T> minValue, Comparable<T> maxValue) throws OpenDataException

Constructs an OpenMBeanParameterInfoSupport instance, which describes the parameter used in one or more operations or constructors of a class of open MBeans, with the specified name, openType, description, defaultValue, minValue and maxValue. It is possible to specify minimal and maximal values only for an open type whose values are Comparable.

public OpenType<?> getOpenType()

Returns the open type for the values of the parameter described by this OpenMBeanParameterInfoSupport instance.

public Object getDefaultValue()

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

public Set<?> getLegalValues()

Returns an unmodifiable Set of legal values for the parameter described by this OpenMBeanParameterInfoSupport instance, if specified, or null otherwise.

public Comparable<?> getMinValue()

Returns the minimal value for the parameter described by this OpenMBeanParameterInfoSupport instance, if specified, or null otherwise.

public Comparable<?> getMaxValue()

Returns the maximal value for the parameter described by this OpenMBeanParameterInfoSupport instance, if specified, or null otherwise.

public boolean hasDefaultValue()

Returns true if this OpenMBeanParameterInfoSupport instance specifies a non-null default value for the described parameter, false otherwise.

public boolean hasLegalValues()

Returns true if this OpenMBeanParameterInfoSupport instance specifies a non-null set of legal values for the described parameter, false otherwise.

public boolean hasMinValue()

Returns true if this OpenMBeanParameterInfoSupport instance specifies a non-null minimal value for the described parameter, false otherwise.

public boolean hasMaxValue()

Returns true if this OpenMBeanParameterInfoSupport instance specifies a non-null maximal value for the described parameter, false otherwise.

public boolean isValue(Object obj)

Tests whether obj is a valid value for the parameter described by this OpenMBeanParameterInfo instance.

public boolean equals(Object obj)

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

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

• obj is non null,
• obj also implements the OpenMBeanParameterInfo interface,
• their names are equal
• their open types 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 OpenMBeanParameterInfo interface.

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

public int hashCode()

Returns the hash code value for this OpenMBeanParameterInfoSupport instance.

The hash code of an OpenMBeanParameterInfoSupport instance is the sum of the hash codes of all elements of information used in equals comparisons (ie: its name, its open type, its default, min, max and legal values, and its Descriptor).

This ensures that t1.equals(t2) implies that t1.hashCode()==t2.hashCode() for any two OpenMBeanParameterInfoSupport instances t1 and t2, as required by the general contract of the method Object.hashCode().

However, note that another instance of a class implementing the OpenMBeanParameterInfo interface may be equal to this OpenMBeanParameterInfoSupport instance as defined by equals(java.lang.Object), but may have a different hash code if it is calculated differently.

As OpenMBeanParameterInfoSupport instances are immutable, the hash code for this instance is calculated once, on the first call to hashCode, and then the same value is returned for subsequent calls.

public String toString()

Returns a string representation of this OpenMBeanParameterInfoSupport instance.

The string representation consists of the name of this class (i.e. javax.management.openmbean.OpenMBeanParameterInfoSupport), 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 OpenMBeanParameterInfoSupport 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.
