interface StringToObjectConverter

Internal API for converting arguments of type String to a specified target type.

Method Summary

Modifier and Type	Method and Description
boolean	canConvert(java.lang.Class<?> targetType) Determine if this converter can convert from a String to the supplied target type (which is guaranteed to be a wrapper type for primitives — for example, Integer instead of int).
java.lang.Object	convert(java.lang.String source, java.lang.Class<?> targetType) Convert the supplied String to the supplied target type (which is guaranteed to be a wrapper type for primitives — for example, Integer instead of int).
default java.lang.Object	convert(java.lang.String source, java.lang.Class<?> targetType, java.lang.ClassLoader classLoader) Convert the supplied String to the supplied target type (which is guaranteed to be a wrapper type for primitives — for example, Integer instead of int).

Method Detail

canConvert

boolean canConvert(java.lang.Class<?> targetType)

Determine if this converter can convert from a String to the supplied target type (which is guaranteed to be a wrapper type for primitives — for example, Integer instead of int).

convert

java.lang.Object convert(java.lang.String source,
                         java.lang.Class<?> targetType)
                  throws java.lang.Exception

Convert the supplied String to the supplied target type (which is guaranteed to be a wrapper type for primitives — for example, Integer instead of int).

Throws:

java.lang.Exception

convert

default java.lang.Object convert(java.lang.String source,
                                 java.lang.Class<?> targetType,
                                 java.lang.ClassLoader classLoader)
                          throws java.lang.Exception

Convert the supplied String to the supplied target type (which is guaranteed to be a wrapper type for primitives — for example, Integer instead of int).

The default implementation simply delegates to convert(String, Class). Can be overridden by concrete implementations of this interface that need access to the supplied ClassLoader.

Throws:

java.lang.Exception
