  +--org.apache.tools.ant.taskdefs.optional.jmx.converter.ValueFactory

All Implemented Interfaces:

ValueConverter

public class ValueFactory

extends java.lang.Object

implements ValueConverter

ValueFactory is a singleton implementation of ValueConverter and is considered the main entry point for ValueConverter clients. Clients should use this ValueFactory class rather than individual ValueConverter implementations. ValueConverter implementations are registered with ValueFactory using the Main factory for all ValueConverter implementations.

Method Detail

getInstance

public static ValueFactory getInstance()

Returns the singleton instance of ValueFactory.

registerValueConverter

public void registerValueConverter(ValueConverter converter)

Registers a ValueConverter with this ValueFactory. After the ValueConverter has been registered, the ValueFactory will automatically delegate calls to its valueOf() method to the appropriate ValueConverter for the type being referenced.

Parameters:

converter - The ValueConverter to register.

valueOf

public java.lang.Object valueOf(java.lang.String value,
                                java.lang.String type)
                         throws java.lang.Exception

Description copied from interface: ValueConverter

Converts the specified string value to the specified type (java primitive type or java class name).

Specified by:

valueOf in interface ValueConverter

Following copied from interface: org.apache.tools.ant.taskdefs.optional.jmx.converter.ValueConverter

Parameters:

value - The attribute value.

type - The java primitive type or class name.

getSupportedTypes

public java.lang.String[] getSupportedTypes()

Description copied from interface: ValueConverter

Returns an array of types (Java class names, or Java primitives) this converter supports.

Specified by:

getSupportedTypes in interface ValueConverter

Following copied from interface: org.apache.tools.ant.taskdefs.optional.jmx.converter.ValueConverter

Returns:

An array of supported type names.

arrayToString

public static java.lang.String arrayToString(java.lang.Object array)

Stringifies an array.

toString

public static java.lang.String toString(java.lang.Object value)

Stringifies a value - can handle array and non-array values.
