Class PropertyVariableInterpolator
java.lang.Object
org.apache.wicket.util.string.interpolator.VariableInterpolator
org.apache.wicket.core.util.string.interpolator.PropertyVariableInterpolator
- All Implemented Interfaces:
- Serializable, IClusterable
- Direct Known Subclasses:
- ConvertingPropertyVariableInterpolator
public class PropertyVariableInterpolator
- extends VariableInterpolator
Interpolates values into String
s that are produced by interpreting property
expressions against an object.
Takes a string such as "My name is ${name}
" and a bean such as a Person
, and reflects on the object using any property expressions found inside ${}
markers
in the String
. In this case, if the Person
model has a
getName()
method. The results of calling that method would be substituted for
${name}
. If getName()
returned "Jonathan"
, then the result
would return "My name is Jonathan"
.
"$" is the escape char. Thus "$${text}" can be used to escape it (ignore interpretation). If
'$3.24' is needed then '$$${amount}' should be used. The first $ sign escapes the second, and the
third is used to interpolate the variable.
