public class ToByte
extends java.lang.Object
implements Converter<java.lang.Byte>

Converts various types to byte values. This converter is registered under the ^byte name.

Like all converters, this type supports conversion from its own target type (i.e. Byte) and the String type. Any given string will be evaluated as an expression and the result of that evaluation will be evaluated as a byte value. For any other type, null is returned.

Method Detail

fromObject

public java.lang.Byte fromObject(java.lang.Object obj,
                                 TerpContext ctx)

Converts the given object into an object of the target type. Conversions can be implemented in any way that makes sense. Normally, converters will return null for null, but some converters may choose to interpret null as an indicator to return a default-initialized target object. An example of this type of conversion is the ShellExecutor. null simply indicates that no preference overrides of any kind have been provided.

Specified by:

fromObject in interface Converter<java.lang.Byte>

Parameters:

obj - the source object.

ctx - the context in which the conversion takes place.

Returns:

an instance of the target type or null.
