Class ToDate

java.lang.Object
  com.codemesh.terp.eval.converters.ToDate

All Implemented Interfaces:

Converter<java.util.Date>

public class ToDate
extends java.lang.Object
implements Converter<java.util.Date>

Converts various types to Dates. This converter is registered under the ^date name.

Like all converters, this type supports conversion from its own target type (i.e. Date) and the String type. Any given string will be evaluated as an expression and the result of that evaluation will be evaluated as a Date value. This converter also supports conversions from numeric types. Any number will be converted to a Date via the Date.Date(long) constructor. For any other type, null is returned.

Method Detail

fromObject

public java.util.Date 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.util.Date>

Parameters:
