Method Detail

getParameterSignature

public Class[] getParameterSignature()

Description copied from interface: Expression

Returns the parameter signature for this Expression. Because the sub-expressions within the Expression are typically arguments or operands, some type validation is performed by examining the class types of the sub-expressions against the Expression's parameter signature.
The tests that are performed are:
1. The number of sub-expressions must equals the number of parameter entries.
2. The class type of any sub-expression (or the result of evaluating the sub-expresssion) must equal the class type of the corresponding parameter entry.
3. Any null parameter entries are ignored and are considered optional sub-expressions.

Returns

the Class array containing the parameter signature.
