public final class StringEqualsIgnoreCase
extends StringOperator
implements BinaryOperator

Implementation of the StringEqualsIgnoreCase operator.
Input 1: A String (or Expression returning a String) that is LHS of the operator.
Input 2: A String (or Expression returning a String) that is RHS of the operator.
Returns: A Boolean: LHS.equalsIgnoreCase( RHS ).

Method Detail

getLeftHandSide

public Object getLeftHandSide()
Description copied from interface: BinaryOperator
Returns left hand side operand of this binary operator.

Specified by:
getLeftHandSide in interface BinaryOperator
Returns
The left hand side operand.

getRightHandSide

public Object getRightHandSide()
Description copied from interface: BinaryOperator
Returns right hand side operand of this binary operator.

Specified by:
getRightHandSide in interface BinaryOperator
Returns
The left hand side 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.
