public final class PropertyVariableInterpolator
Interpolates values into String
s that are produced by interpreting property
expressions against a beans model.
The interpolate(String string, Object model)
method takes a string such as "
My name is ${name}
" and a beans model 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 ${name}
. If
getName()
returned "Jonathan"
, then interpolate()
would
return "My name is Jonathan"
.
"$" 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.
