Method Detail

getOperand

public Object getOperand()
Description copied from interface: UnaryOperator
Returns unary operand.

Specified by:
getOperand in interface UnaryOperator
Returns
An unary operand.

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.

Specified by:
getParameterSignature in interface Expression
Returns
the Class array containing the parameter signature.
