com.tangosol.coherence.config.ParameterMacroExpression
public class ParameterMacroExpression
A ParameterMacroExpression
is an Expression
representing the use of a Coherence Parameter Macro, typically occurring with in a Coherence Cache Configuration file.
Coherence Macro Parameters are syntactically represented as follows:
{parameter-name [default-value]}
When a ParameterMacroExpression
is evaluated the parameter-name and it's associated value is resolved by consulting the provided ParameterResolver
. If the parameter is resolvable, the value of the resolved parameter is returned. If it's not resolvable the default value is returned.
Note: Returned values are always coerced into the type defined by the Expression
.
